How to send a document data souce to a custom control in XPages?

问题

I have this computed text bound to a the body field using EL

 <xp:text escape="true" id="computedField1" value="#{doc.Body}"></xp:text>

Now I need to store this computedField in a Custom Control and send in the doc? What property definition should I use, and how do I reference the compositeData to the Body field in the cc

thanks

Thomas

Create a custom property on your Custom Control called dataSource and set the type to com.ibm.xsp.model.DataSource

Create a second custom property called computedFieldName and set it's type to string

In the computed field in the custom control set the value like

value="#{compositeData.dataSource[compositeData.computedFieldName]}"

When using the custom control just set the custom properties like:

computedFieldName="Body" dataSource="#{doc}"
