Hello,
You probably want to use a booleanProperty instead of a checkSelectionProperty.
The checkSelectionProperty allows to select multiple values (you use
it only for one). It always set the property (even if empty), so your
<target if=""> statements will get executed as they test the property
existence and not value.
You could still go with checkSelectionProperty, using an antcontrib
<for> or <foreach> to loop on the result list.
But it might be easier to just go with booleanProperty.
Rgds,
Patrick
