Question

当我使用smartgwt 2.2时，我的smartgwt有问题，但是当我使用smartgwt 4.0b（夜间构建）时，我遇到了错误：

00:00:48,253 [ERROR] Uncaught exception escaped
com.google.gwt.core.client.JavaScriptException: (null) @com.smartgwt.client.widgets.tree.Tree::create()([]): null   at com.google.gwt.dev.shell.BrowserChannelServer.invokeJavascript(BrowserChannelServer.java:249)    at com.google.gwt.dev.shell.ModuleSpaceOOPHM.doInvoke(ModuleSpaceOOPHM.java:136)    at com.google.gwt.dev.shell.ModuleSpace.invokeNative(ModuleSpace.java:571)  at com.google.gwt.dev.shell.ModuleSpace.invokeNativeObject(ModuleSpace.java:279)    at com.google.gwt.dev.shell.JavaScriptHost.invokeNativeObject(JavaScriptHost.java:91)   at com.smartgwt.client.widgets.tree.Tree.create(Tree.java)  at com.smartgwt.client.core.BaseClass.getOrCreateJsObj(BaseClass.java:120)  at com.smartgwt.client.widgets.tree.TreeGrid.setData(TreeGrid.java:2393)    at pl.fizzycomp.departments.gwt.client.DepartmentsMainView.setModelData(DepartmentsMainView.java:175)   at com.test.departments.gwt.client.DepartmentsMainPresenter.setDepartments(DepartmentsMainPresenter.java:208)   at com.test.gwt.client.DepartmentsApp$2.onSuccess(DepartmentsApp.java:80)   at com.test.gwt.client.DepartmentsApp$2.onSuccess(DepartmentsApp.java:1)

我不知道这是什么问题这是我在DepartmentsMainView中的代码：

tree = new Tree();
tree.setModelType(TreeModelType.PARENT);
tree.setNameProperty(DepartmentTreeNode.NAME_FIELD);
tree.setParentIdField(DepartmentTreeNode.PARENT_ID_FIELD);
tree.setIdField(DepartmentTreeNode.ID_FIELD);


tree.setData(nodes.toArray(new DepartmentTreeNode[nodes.size()]));          

grid.setData(tree);

和我的DepartmentTreeNode：

public class DepartmentTreeNode extends TreeNode implements IDepartmentTreeNode {
    public static final String ID_FIELD = "idField";
    public static final String NAME_FIELD = "nameField";
    public static final String CODE_FIELD = "codeField";
    public static final String DESCRIPTION_FIELD = "descriptionField";
    public static final String PARENT_ID_FIELD = "parentId";
    public static final String VERSION_FIELD = "versionField";

    public DepartmentTreeNode(DepartmentDto dto) {
        setTitle(dto.getName());

        setAttribute(ID_FIELD, dto.getId());
        setAttribute(PARENT_ID_FIELD, dto.getParentId());
        setDepartmentName(dto.getName());
        setAttribute(CODE_FIELD, dto.getCode());
        setAttribute(DESCRIPTION_FIELD, dto.getDescription());
        setAttribute(VERSION_FIELD, dto.getVersion());
    }

所以它看起来很好我正在通过sysout对它检查对象DepartmentTreeNode它的好处。那有什么不对？

在智能gwt控制台Resoult中我只得到了信息：

16:03:28.848:WARN:Log:NOTE: Firebug is enabled. Firebug greatly slows the performance of applications that make heavy use of JavaScript.

我也清理我的项目mvn clean install，我认为这不是每晚构建的问题。因为如果我使用的是smartgwt2.5，我会收到此错误：/

每晚构建错误确实属于SmartGWT论坛。它很可能是一个错误。

您应该确保的另一件事是您的项目是干净的旧生成代码。要确定，请删除war目录中的任何旧生成代码。

最后，使用SmartGWT控制台：http://www.smartclient.com/smartgwt/javadoc/com/smartgwt/client/docs/Debugging.html - 它有时会使这些神秘错误更加清晰
