Don't do this! setParent() is called for you. Don't ever call
it on your own (see the Javadoc).

You want text.setValueExpression() - the problem will be that
your ValueExpression is wrong. It needs to be something like:
ValueExpression value =
ef.createValueExpression(elContext,"#{row.xxx}",String.class);
