<component name="empComp" class="component.EmpComponent">
<property name="EmpId" type="java.lang.String" column="Emp_ID" not-null="true" length="10"/>
<property name="EmpName" formula="
(select EmpName from Emp where Emp.Emp_id=EmpId)" />
</component>

Well thats pretty clear, isn't it? You cant use formula inside of a component.

I have EmpTO available in memory how to retrieve value for empName from EMPTO and assign it to component property
