Hi,

i'm interested to display and change the priority of MADescription components when the browser display Halos.

For example i have a class with descriptionA, descriptionB.

For display the priority i change the WAClassnameHaloPlugin renderOn: method.

For change i create the WAPriorityHaloPlugin.

In the relative execute method i test if component is anMAComponent : self target description respondTo: #priority .

If yes i,m interested to open the Browser or WABrowser on the relative descriptionA.

The first question is: how i can define the name of descriptionA from anObject with magritte structure ?

into execute context of WAPriorityHaloPlugin i see aObject with memento, description, accessor ..... but i d'ont found link to the relative generating descriptionA.

Given that aObject's description is a container you can iterate through the contained descriptions looking for a match on the selector of the description.
aObject description detect: [ :each | each accessor selector = #theSelectorIWant ]

The second question is: after change the descriptionA with the WABrowser and return to the halo browser how i can update the view to reflect the change ?

i have do some test but for now ti need to close and reopen the view.

Descriptions are cached so sending #flush to MANamedBuilder default forces the (container) descriptions to be rebuilt with the modified descripitons. I dont know if that will work well in your situation.

Best of luck with it
John

Thanks for any considerations.
