Re: [Wonder-disc] D2WList and inheritance

[Patrice G. <pa...@ma...>]

Hi Anjo,

Here is the way it's set up right now:

in ERD2WListPage, we test to see if the context can provide an  
editConfigurationName. If not, we call super, and this eventually calls  
D2W.factory().inspectPageForEntityNamed(object().entityName(),session()) 
  which should do the right thing in an inheritance situation. So I am  
assuming you have rule that looks like   pageName='MyListPage' -->   
editConfigurationName='MyEditConfiguration'

Couple of things you can do:

1/ as you suggested, write rules like:
	
	 pageName='MyListPage' and object.entityName='Asset' -->   
editConfigurationName='EditAsset'

this will cause object.entityName (not just object) to become a  
significant key for editConfigurationName, which is fine

2/ you could also write a custom delayed assignment to compute the name  
of the configuration you want..

I guess the decision depends on how often you are going to do this. If  
it's often, 2/ might make more sense..


Hope this helps,



	-P
