I switched to using the .wo (no inline binding for these objects) and used your //valid switch.

UserNameField: WOTextField {
	value = userDG.selectedObject.username; //valid
	size = "35";
}

worked like a charm.

I don't understand why this same line from a different component throws no error:

<wo:WOTextField value = "$dg.selectedObject.salutation" size = "35" />

I understand that selectedObject could be any type but $dg.selectedObject is an object of type dg which is defined.

I could not get the //valid to work with the inline binding so I pushed everything into the .wo.

Thanks for a solution.

Ted
