yeah great it finally works !!! thank you very much !
<item whenRequired="Parse">istep:type=Properties,name=SystemProperties</item>
was the last step on the "deploying of myapp.ear/my-ds.xml with ${max-pool-size}" journey :-)
looking back on the interesting evolution of this forum thread there are a plenty of usefull hints which may be worth noting in a separate wiki article
I'm willing to write it down
btw why whenRequired="Parse" ?
Parse is a deployment stage but whenRequired attribute representation in DependencyItemMetaData class is a controller state ?
public class DependencyItemMetaData implements Serializable {
private Object value;
private ControllerState whenRequired = ControllerState.DESCRIBED;
private ControllerState dependentState;
