Acumatica-从PXSelector选择的项目时不加载字段

Question

当从选择器中选择一个值时，我很难加载我的字段。第一个屏幕（组类别）具有一个组选择器，该组选择器在文本字段和网格中显示描述，用户可以在其中输入类别和目录描述。这很完美。

// Group DAC 
[Serializable]
public class INMerchandiseGroup : IBqlTable
{
    #region GroupCD
    [PXDBString(10, IsKey = true, BqlField = typeof(INMerchandiseGroup.groupCD))]    
    [PXUIField(DisplayName = "Group Code", Visibility=PXUIVisibility.SelectorVisible)]
    [PXSelector(typeof(Search<INMerchandiseGroup.groupCD>),
    typeof(INMerchandiseGroup.groupCD),
    typeof(INMerchandiseGroup.description))]
    public virtual string GroupCD { get; set; }
    public abstract class groupCD : PX.Data.BQL.BqlString.Field<groupCD> { }
    #endregion

    #region Description
    [PXDBString(256, IsUnicode = true, BqlField = typeof(INMerchandiseGroup.description))]
    [PXUIField(DisplayName = "Description")]
    public virtual string Description { get; set; }
    public abstract class description : PX.Data.BQL.BqlString.Field<description> { }
    #endregion
}

// Group Graph
public class BPGroupCategoryMaint : PXGraph<BPGroupCategoryMaint, INMerchandiseGroup>
{    
    // Setup for GroupCd in grid 
    #region Category GroupCD
    [PXMergeAttributes(Method = MergeMethod.Append)]
    [PXDBDefault(typeof(INMerchandiseGroup.groupCD))]
    protected virtual void INMerchandiseCategory_GroupCD_CacheAttached(PXCache cache)
    {
    }
    #endregion   

    public PXSelect<INMerchandiseGroup> CurrentGroup;
    public PXSave<INMerchandiseGroup> Save;
    public PXCancel<INMerchandiseGroup> Cancel;

    public PXSelect<INMerchandiseCategory,
    Where<INMerchandiseCategory.groupCD, Equal<Current<INMerchandiseGroup.groupCD>>>>
    GroupCategories;
}

我在“类别-部门”屏幕中具有相同的设置。用户从选择器中选择类别，“类别描述和组CD”应填充文本框，但类别描述和groupcd仅在第一次填充。在那之后，缓存中的值为空。我在做什么错？

// Category DAC (this is used in the grid of Group screen, and as a record header in Category screen.
[Serializable]
public class INMerchandiseCategory : IBqlTable
{     
    #region CategoryCD
    [PXDBString(10,  IsKey = true, BqlField = typeof(INMerchandiseCategory.categoryCD, InputMask = ">CCCCCCCCCC")]
    [PXUIField(DisplayName = "Category Code")]
    public virtual string CategoryCD { get; set; }
    public abstract class categoryCD : PX.Data.BQL.BqlString.Field<categoryCD> { }       
    #endregion

    #region Description
    [PXDBString(256, IsUnicode = true, BqlField = typeof(INMerchandiseCategory.categoryDescription))]
    [PXUIField(DisplayName = "Category Description")]
    public virtual string CategoryDescription { get; set; }
    public abstract class categoryDescription : PX.Data.BQL.BqlString.Field<categoryDescription> { }
    #endregion

    #region GroupCD
    [PXDBString(10, IsKey = true, BqlField = typeof(INMerchandiseCategory.groupCD) )]
    [PXUIField(DisplayName = "Group Code")]
    public virtual string GroupCD { get; set; }
    public abstract class groupCD : PX.Data.BQL.BqlString.Field<groupCD> { }
    #endregion      
}

// Category Graph
public class BPCategoryDeptMaint : PXGraph<BPCategoryDeptMaint>
{
    [PXMergeAttributes(Method = MergeMethod.Merge)]
    [PXUIField(DisplayName = "Category Code", Visibility=PXUIVisibility.SelectorVisible)]   
    [PXSelector(typeof(Search2<INMerchandiseCategory.categoryCD,
    InnerJoin<INMerchandiseGroup, On<INMerchandiseCategory.groupCD, Equal<INMerchandiseGroup.groupCD>>>>),
    typeof(INMerchandiseCategory.categoryCD),
    typeof(INMerchandiseCategory.categoryDescription),
    typeof(INMerchandiseCategory.groupCD),
    typeof(INMerchandiseGroup.description))]    
    protected virtual void INMerchandiseCategory_CategoryCD_CacheAttached(PXCache cache)
    {

    }

    #region Dept GroupCD
    [PXMergeAttributes(Method = MergeMethod.Append)]
    [PXDefault(typeof(INMerchandiseCategory.groupCD), PersistingCheck = PXPersistingCheck.Nothing)]
    protected virtual void INMerchandiseDept_GroupCD_CacheAttached(PXCache cache)
    {
    }
    #endregion     

    #region Dept CategoryCD
    [PXMergeAttributes(Method = MergeMethod.Append)]
    [PXDefault(typeof(INMerchandiseCategory.categoryCD), PersistingCheck = PXPersistingCheck.Nothing)]
    protected virtual void INMerchandiseDept_CategoryCD_CacheAttached(PXCache cache)
    {
    }
    #endregion     

    public PXSelect<INMerchandiseCategory> CurrentCategory;
    public PXSave<INMerchandiseCategory> Save;
    public PXCancel<INMerchandiseCategory> Cancel;

    public PXSelect<INMerchandiseDept,
    Where<INMerchandiseDept.groupCD, Equal<Current<INMerchandiseCategory.groupCD>>,
    And<INMerchandiseDept.categoryCD, Equal<Current<INMerchandiseCategory.categoryCD>>>>>
    CategoryDepts;            
    }
}

请确保ASPX中的字段具有属性commit = true。如果标记为提交，则在控件更改时，UI会将更新发送到服务器。
