呈现为下拉的智能字段不显示描述 [英] Smart fields that are rendered as drop down does not show description

问题描述

我有一个像这样定义的智能字段:

I have a smart field that I defined like this:

<smartField:SmartField value="{MarktID}" textInEditModeSource="ValueList" >
    <smartField:configuration>
        <smartField:Configuration preventInitialDataFetchInValueHelpDialog="false" displayBehaviour="idAndDescription"/>
    </smartField:configuration>
</smartField:SmartField>

呈现方式如下(即下拉或选择):

it's rendered like this (i.e. as drop down or select):

因为我的注释文件中有这个定义:

because I have this definition in my annotation file:

<Annotations Target="Metadata.Meldungen/MarktID">
    <Annotation Term="Common.ValueListWithFixedValues" Bool="true"/>
    <Annotation Term="Common.ValueList">
        <Record>
            <PropertyValue Property="CollectionPath" String="MarktSet"/>
            <PropertyValue Property="Parameters">
                <Collection>
                    <Record Type="Common.ValueListParameterOut">
                        <PropertyValue Property="LocalDataProperty" PropertyPath="MarktID"/>
                        <PropertyValue Property="ValueListProperty" String="ID"/>
                    </Record>
                    <Record Type="Common.ValueListParameterDisplayOnly">
                        <PropertyValue Property="ValueListProperty" String="Name"/>
                    </Record>
                </Collection>
            </PropertyValue>
        </Record>
    </Annotation>
</Annotations>

问题是如何在下拉列表中显示所选项目的名称.我的意思是不想显示 1300 (1300)(如图所示)，我想在下拉菜单中显示 1300 (Cimt Handelsgruppe).

The question is how can I show the name of the selected item also in the drop down. I mean instead of showing 1300 (1300) (as can be seen in the picture) I want to show 1300 (Cimt Handelsgruppe) in the drop down itself.

现在好像不知道括号里要显示什么！?

It seems at the moment it does not know what to show in the parenthesis!?

推荐答案

最终我找到了解决方案！

Eventually I found the solution!

以下是包含下拉菜单数据的实体的定义:

Here is the definition of entity that contains the data regarding the drop-down:

<EntityType Name="Markt" sap:content-version="1">
    <Key>
        <PropertyRef Name="ID"/>
    </Key>
    <Property Name="ID" Type="Edm.String" Nullable="false" MaxLength="4" sap:display-format="UpperCase" sap:label="ID" sap:text="Name"/>
    <Property Name="Name" Type="Edm.String" Nullable="false" sap:label="Name"/>
</EntityType>

我的定义中缺少的是sap:text=Name".通过添加这个小属性，智能字段知道它必须在 displayBehaviour 等于 idAndDescription 或 descriptionAndId<时将哪个属性显示为 description/代码>.

What was missing in my definition was sap:text="Name". By adding this small property the smart field know it has to show which property as description when the displayBehaviour is equal idAndDescription or descriptionAndId.

我终于得到了我想要的:

Finally I had what I wanted:
