Transformation Editor (Dozer): deep nested variable mapping create two VariableMapper but only one is supported.

XMLWordPrintable

      Environment: Red Hat CodeReady Studio 12.13.0.GA

         <mapping>
        <class-a>ClassA</class-a>
        <class-b>ClassB</class-b>
        <field custom-converter-id="_variableMapping" custom-converter-param="${Ky}">
            <a>literal</a>
            <b>x.y.value</b>
        </field>

      Created another mapping as this one, that Dozer ignore:

         <mapping>
        <class-a>ClassA</class-a>
        <class-b>ClassB$X$Y$Z</class-b>
        <field custom-converter-id="_variableMapping" custom-converter-param="${Kz}">
            <a>literal</a>
            <b>value</b>
        </field>

      Instead, this one that works but broke the Transformation Editor with an NPE.

              <field custom-converter-id="_variableMapping" custom-converter-param="${Kz}">
            <a>literal</a>
            <b>x.y.z.value</b>
        </field>
