Missing get*_UU methods

Hi,

I have made some very specific customization on trees on swingUI (360). It uses new tables and thier model classes.
To put it in idempiere zk, i had to put these model classes in the org.adempiere.model to be able to modify some core classes (MTree, ADTree...)

But how can i get the current ID of the tab for instance ?
If i understand well, i need to use UUID (instead of ID) but there is not getUU method available for GridTab ... Is this planned (as it is available in GridWindow) ?

Same problem for ProcessInfo where there is no getProcess_UU method

Thanks & regards,

Nicolas
