Question

我正在使用ColdBox 3.5和ColdFusion 10 ORM开发博客应用程序，我随机收到以下错误消息：

错误类型：应用程序：[N / A]

错误消息：Hibernate操作中的异常。   更新/删除的行不存在或会话包含过时数据。

根本原因：org.hibernate.StaleObjectStateException：行被另一个事务更新或删除（或未保存的值映射不正确）：[Entry＃297e1bfa369cf17501369d26ffae00a4]

/model/entry/Entry.cfc ：

component
    persistent="true"
    table="Entry"
    output="false"
{
    // primary key
    property name="entryID" fieldtype="id" ormtype="string" type="string" length="32" generator="uuid";

    // properties
    property name="title" fieldtype="column" ormtype="string" type="string" length="100" notnull="true";
    property name="alias" fieldtype="column" ormtype="string" type="string" length="100" notnull="true";
    property name="body" fieldtype="column" ormtype="string" type="string" sqltype="nvarchar(max)" notnull="true";
    property name="allowComments" fieldtype="column" ormtype="boolean" type="boolean" sqltype="bit" dbdefault="1" default="true" notnull="true";
    property name="released" fieldtype="column" ormtype="boolean" type="boolean" sqltype="bit" dbdefault="1" default="true" notnull="true";
    property name="releasedDate" fieldtype="column" ormtype="timestamp" type="date";
    property name="addDate" fieldtype="timestamp" ormtype="timestamp" type="date";

    property name="comments" fieldtype="one-to-many" cfc="model.entryComment.EntryComment" fkcolumn="entryID" singularname="comment" cascade="all-delete-orphan";
    property name="user" fieldtype="many-to-one" cfc="model.user.User" fkcolumn="userID" notnull="true" cascade="save-update";
    property name="views" fieldtype="one-to-many" cfc="model.entryView.EntryView" fkcolumn="entryID" singularname="view" cascade="all-delete-orphan";

    // validation
    this.constraints = {
        "title" = {"required" = true},
        "body" = {"required" = true},
        "allowComments" = {"required" = true, type="boolean"},
        "released" = {"required" = true, type="boolean"},
        "categories" = {size=1},
        "user" = {type="component"}
    };
}

/model/category/Category.cfc ：

component
    persistent="true"
    table="Category"
    schema="system"
    output="false"
{
    // primary key
    property name="categoryID" fieldtype="id" ormtype="string" type="string" length="32" generator="uuid";

    // properties
    property name="name" fieldtype="column" ormtype="string" type="string" length="50" notnull="true";
    property name="alias" fieldtype="column" ormtype="string" type="string" length="50" notnull="true";
    property name="description" fieldtype="column" ormtype="string" type="string" default="" length="200";
    property name="addDate" fieldtype="timestamp" ormtype="timestamp" type="date";
    property name="active" fieldtype="column" ormtype="boolean" type="boolean" sqltype="bit" dbdefault="1" default="true" notnull="true";

    // relations
    property name="entries" fieldtype="many-to-many" cfc="model.entry.Entry" linktable="EntryCategory" fkcolumn="categoryID" inversejoincolumn="entryID" lazy="true" cascade="all" singularname="entry" inverse="true";

    // validation
    this.constraints = {
        "name" = {"required" = true},
        "active" = {"required" = true, type="boolean"}
    };
}

这是我正在运行的代码：

<cfscript>
    entry = entityNew("Entry", {
        "title" = "test",
        "body" = "test",
        "alias" = "test",
        "allowComments" = 0,
        "released" = 0,
        "user" = entityLoadByPK("User", "297e1bfa3697d377013697f53ca10084")
    });

    // works 1 out of 5 times
    entry.setCategories([entityLoadByPK("Category", "297e1bfa36986e69013698c3e54f000d")]);

    // works every time
    //entry.setCategories(entityLoad("Category", "297e1bfa36986e69013698c3e54f000d"));
    //entry.setCategories(entityLoad("Category"));

    entitySave(entry);
    ormFlush();
</cfscript>

请注意标有“5次中有1次”和“每次都有效”的部分。我不知道我做错了什么。我有其他类似的对象，他们使用链接表，我收到类似的错误消息。我查看了SQL日志。准备插入EntryCategory表时似乎发生错误。有什么想法吗？

使用HQL并使用（？）中的ID。这非常有效。

如果实体已有数组，请先使用ArrayClear（）。

更新：

categories = ormExecuteQuery("from Category where Id IN (:Ids)",
                             {Ids=listToArray(FORM.categoryIDs)});
entry.setCategories(categories);

ORM - 链接表错误
