Question

我们的目标是实现预填充的文档创建表单，其中包含从PluginService对象检索的值。

当用户右键单击某个文档并选择“来自此文档的新文档”时，它会触发Action，这会打开AddContentItemDialog。然后，调用该服务以检索所选文档的属性（可能没有必要，通过Firefox开发人员面板，我看到大多数，可能已经提取了所有自定义属性）。

我可以填写文本字段属性，但不能填充ChoiceList属性：虽然可能在内部填充，但它们不会更新。

这是一个注释的代码示例：

require(["dojo/_base/declare",
         "dojo/_base/lang",
         "dojo/aspect", 
         "ecm/model/Request",
         "ecm/widget/dialog/AddContentItemDialog"], 
function(declare, lang, aspect, Request, AddContentItemDialog) {        

    // Parameters passed to the service as HttpServletRequest
    // (Custom function)
    var serviceParams = getServicesParams(items[0]);

    // Object store and parentFolder retrieving (needed below)
    var parentFolder = items[0].parent;
    var objectStore = items[0].objectStore;

    // Retrieving the template to use for the dialog
    // (Custom function)
    var entryTemplate = retrieveTemplate(objectStore, parentFolder); 

    // Service call 
    Request.invokePluginService("FormPlugin", "FormService", {
        requestParams: serviceParams,
        requestCompleteCallback: function(response) {
            // Creating the global dialog  box
            var addContentItemDialog  = new AddContentItemDialog();
            // Box containing the document properties
            var addContentItemPropertiesPane =
                addContentItemDialog.addContentItemPropertiesPane;
            // Box containing general stuff
            var addContentItemGeneralPane =
                addContentItemDialog.addContentItemGeneralPane;

            // Showing the dialog box 
            addContentItemDialog.show(
                repository,
                parentFolder,  /* parent folder       */
                true,          /* document being added*/
                false,         /* not virtual          */
                null,          /* no callback function */
                null,          /* no teamspace */
                true,          /* use an entry template */
                entryTemplate, /* entry template */
                true           /* can't choose directory from another rep */
           );

            // Waiting for complete rendering before filling the properties and general fields
            aspect.after(addContentItemPropertiesPane,
                         "onCompleteRendering",
                         function() {
                             // Setting the destination and lock it
                             var folderSelector = addContentItemGeneralPane.folderSelector;
                             folderSelector.setRoot(parentFolder, objectStore);
                             folderSelector .setDisabled(true);

                             // Property filling - Work :-)
                             addContentItemDialog.setTitle("New document from another");
                             addContentItemDialog.setIntroText("This form allow you to create a document from another one.");
                             addContentItemPropertiesPane.setPropertyValue("DocumentTitle", "Prefilled title");                            
                             // Property filling - Doesn't work :-(
                             addContentItemPropertiesPane.setPropertyValue("A_ChoiceList_Prop",
                                    [ "Value\\1", "Value\\2", "Value\\3"]);

                         }, true);
            }
        });
    });
});

也许我错过了一些神奇的IBM代码行来完成它。

Answer 1

已更新。 1）代码现在正在等待检索条目模板内容。 2）这个答案也适用于以前版本的ICN。 3）这个答案定义了全球范围内的功能。 要非常小心，您可能会遇到与其他插件和ICN代码冲突的名称。而是使用回调函数，或者“强烈”命名您的函数。

我按照以下步骤编写了插件操作：

检索源文档和父文件夹
调用插件服务，该服务获取所单击文档的属性
检索条目模板并使用提取的属性
创建一个EntryTemplate对象，并通过向其传递条目模板来显示它。

条目模板由propertiesOptions对象描述。它有一个引用数组的键defaultValue。此数组的每个元素表示一个Document Property。每个元素都包含一个名为EntryTemplate { addClassDescription: "An Entry Template", addClassLabel: "An Entry Template", addClassName: "AnEntryTemplate", // [...] propertiesOptions: [ { dataType: "xs:string", id: "a_prop", name: "A Property", // [...] defaultValue: "A default value", // [...] }, // [...] ], // [...] }的键：

yyyy-MM-ddTHH:mm:ss

字符串值作为（显然）字符串传递，日期作为ISO8601格式化字符串（n1）和列表作为数组传递。

例如，给定n2，n3，propertyOption // "xs:string" dataType entryTemplate.propertiesOptions[n1].defaultValue = "Duck"; // "xs:timestamp" dataType entryTemplate.propertiesOptions[n2].defaultValue = "1938-04-15T00:00:00"; // "xs:string" dataType, "LIST" cardinality entryTemplate.propertiesOptions[n3].defaultValue = ["Huey", "Dewey", "Louie"];条目：

require(["dojo/_base/declare",
         "dojo/_base/lang",
         "dojo/aspect", 
         "ecm/model/Request",
         "ecm/widget/dialog/AddContentItemDialog"], 
         function(declare, lang, aspect, Request, AddContentItemDialog) {
    /**
     * Use this function to add any global JavaScript methods your plug-in requires.
     */

    lang.setObject("openFilledCreateDocumentFormAction",
            function(repository, items, callback, teamspace, resultSet, parameterMap) {

                // Parameters passed to the service as HttpServletRequest

                var serviceParams = new Object();
                serviceParams.server = items[0].repository.id;
                serviceParams.serverType = items[0].repository.type;
                serviceParams.id = items[0].id;

                // Object store and parentFolder retrieving (needed below)
                var objectStore = items[0].objectStore;
                var parentFolder = items[0].parent;
                var entryTemplateClassName = null;

                // Service call. "FormService" fetch the source document
                // properties, then put them as JSON in the response.
                // The response will be passed to the function
                // requestCompleteCallback (see below)
                Request.invokePluginService(
                        "FormPlugin",
                        "FormService", {
                            requestParams: serviceParams,
                            // Parameters below are for response callback
                            etClassName:"AnEntryTemplate",
                            repository:repository,
                            objectStore:objectStore,
                            parentFolder:parentFolder,
                            AddContentItemDialog:AddContentItemDialog,
                            aspect:aspect,
                            requestCompleteCallback: processRetrievalResponse
                        });
            });
});

下面是PluginAction的Javascript客户端代码的实现。我没有提供服务实现，也没有提供填写条目模板的代码，因为它有点偏离主题。（有关编写ICN插件的更多信息，请参阅ICN红皮书 Customizing and Extending IBM Content Navigator 。）

请注意，我不认为这个答案是设计Action插件的最佳方式，请不要犹豫，建议相关版本的优化/良好实践。我刚刚发现了imbricate回调函数的痛苦，所以我的目的是在顶层定义它们中的大多数，我不喜欢单片代码。

首先，主要部分：

FormService

processRetrievalResponse()完成后调用function processRetrievalResponse(response) { // Some data passed to the parent object of this callback (see above) var etClassName = this.etClassName; var repository = this.repository; var objectStore = this.objectStore; var parentFolder = this.parentFolder; var AddContentItemDialog = this.AddContentItemDialog; var aspect = this.aspect; // First we'll retrieve all the templates repository.retrieveEntryTemplates( function (entryTemplates, document_ET_count, folder_ET_count) { var entryTemplate = null; // Then we'll search for the one that we want for (var i = 0; i < entryTemplates.length; i++) { if (entryTemplates[i] && entryTemplates[i].addClassName == etClassName) { entryTemplate = entryTemplates[i]; break; } } // No Entry Template = abort. if (!entryTemplate) { alert("The Entry Template " + "\"" + etClassName + "\" " + "was not found. Please contact the administrators"); return; } // Now we got the Entry Template, time to retrieve its content // First, we design a "waiter" object. // We assume here the PluginService returns the values in // the "properties" entry of the object response retrievalWaiter = new RetrievalWaiter (repository, objectStore, parentFolder, entryTemplate, response.properties, AddContentItemDialog, aspect); // Then a call to retrieve its content entryTemplate.retrieveEntryTemplate(null, false, true); // We ignite the waiter. When the retrieval will be performed, // It will fill its default values and use it to display // the creation document dialog. retrievalWaiter.wait(); }, "Document", parentFolder.id, null, objectStore); }。在这一步中，我们将首先检索我们想要的模板。

RetrievalWaiter

while代码。在这里，没有function RetrievalWaiter(repository, objectStore, parentFolder, entryTemplate, properties, AddContentItemDialog, aspect) { this.repository = repository; this.objectStore = objectStore; this.parentFolder = parentFolder; this.entryTemplate = entryTemplate; this.properties = properties; this.aspect = aspect; this.wait = function() { // If the Entry Template is not yet loaded, wait 500 ms // and recheck if (!this.entryTemplate.isRetrieved) { var _this = this; setTimeout(function() {_this.wait();}, 500); return; } // Fill the Entry Template with defaults value // (got from the PluginServer response, see above) fillEntryTemplate(this.entryTemplate, this.properties); // Show the document creation dialog with the showDialog(AddContentItemDialog, this.aspect, this.repository, this.objectStore, this.parentFolder, this.entryTemplate); } }循环，因为它会像恶心一样消耗。该对象仅依赖于setTimeOut（）来定期检查条目模板内容的检索。

function showDialog(AddContentItemDialog, aspect,
                    repository, objectStore,
                    parentFolder,
                    entryTemplate) {
    var addContentItemDialog  = new AddContentItemDialog();
    var addContentItemPropertiesPane =
        addContentItemDialog.addContentItemPropertiesPane;
    var addContentItemGeneralPane =
        addContentItemDialog.addContentItemGeneralPane;

    addContentItemDialog.show(
            repository,
            parentFolder,  // parent folder 
            true,          // document being added
            false,         // not virtual 
            null,          // no callback function 
            null,          // no teamspace 
            true,          // Use an Entry Template 
            entryTemplate, // Entry template 
            true           // don't allow choosing directory
                           // from another repository
    );

    // Use aspect to set the value *after* the complete rendering
    // of the properties pane   
    aspect.after(
            addContentItemPropertiesPane,
            "onCompleteRendering",
            function() {
                addContentItemDialog.setTitle("Duplicate a document");
                addContentItemDialog.setIntroText(
                        "This form is loaded from a right-clicked document.");
                // Removing the help link to make the form looks like
                // the document creation one
                addContentItemDialog.setIntroTextRef("","");
                // Set parent folder and prevent it from being edited.
                addContentItemGeneralPane.folderSelector.setRoot(parentFolder, objectStore);
                addContentItemGeneralPane.folderSelector.setDisabled(true);

            }, true);
}

// This function relies on the PluginService response.
// It takes the Entry Template, a JSON formatted response
function fillEntryTemplate(entryTemplate, jsonResponse) {
    // My mission ends here. :-)
}

现在，是时候展示对话了。
