ReferenceValue target object property in EL [message #1031133]

May I use expression on label to access ReferenceValue target object property?
Like SqlSchemaEditor example, ForeignKey has a ReferencedTable:

    // *** ReferencedTable ***
    
    @Reference( target = Table.class )
    @Service( impl = TableReferenceService.class )
    @Required
    @PossibleValues( property = "/Tables/Name" )
    @XmlBinding( path = "referenced-table" )

    ValueProperty PROP_REFERENCED_TABLE = new ValueProperty( TYPE, "ReferencedTable" );

    ReferenceValue<String, Table> getReferencedTable();
    void setReferencedTable( String value );

In property view I wan't to see the reference table property like that:
<label>${referencedTable.target.otherTableProperty}</label>

Any help will be greatly appreciated!

There is no existing facility to do this. Please open an enhancement request. In the meantime, you should be able to write a custom EL function to accomplish this. See ItemImageFunction in the samples for an example on how to write a function. Note that you will need to listen on ReferenceService in your function to detect when reference target changes.
