[Moose-dev] Re: disappearing menu

Hi Doru, yep, you are right, so i tried and i can reproduce the error by executing the first visualization that you find into the entry "JEAs Visualizations" in the context menu. Than if you try again to open the contextual menu on the "All Data Base tables" entry again the menu is gone. I did investigate a bit further and i guess that the the problem is that i order the Table by name using the method sorted: which is defined into MooseGroup. So the problem is that this method order the entities and than reassign them using self entities: that could create a MooseGroup rather than a MJFAMIXTablesGroup. I tried to modify the visualizations a new ordered collection instead of the group itself and the entry "All Data Base Tables" remains a MJFAMIXTablesGroup. Here the code: MJFAMIXTablesGroup>>>viewUMLTablesOn: view view shape rectangle withoutBorder. view interaction nodraggable. view node: #tables forIt: [ (self sorted: [:a :b | a name < b name ]) do: [:table | table viewUMLTableOn: view.]. view gridLayout]. MooseGroup>>>sorted: aBlock self entities: (self entities sortBy: aBlock) CORRECTION: MJFAMIXTablesGroup>>>viewUMLTablesOn: view | orderedTables | orderedTables := (OrderedCollection withAll: self) sorted: [:a :b | a name < b name ]. view shape rectangle withoutBorder. view interaction nodraggable. view node: #tables forIt: [ orderedTables do: [:table | table viewUMLTableOn: view.]. view gridLayout]. If i'm right it is actually a bug isn't it? I mean if i use the sorted: method i want actually to keep the same group type i don't want to have back a generic MooseGroup. I will not commit the modification so you can reproduce the error in case. Thanks, Fabrizio On 2 Nov 2010, at 16:00, Tudor Girba wrote:
