Custom Module Evaluator not working properly

[hiten_rastogi1]

Hi Folks,

After creating a custom module using  <a href="http://docs.alfresco.com/5.1/tasks/dev-extensions-share-tutorials-add-menuitem-create-menu.html">this</a> tutorial I have created a custom module evaluator which should disable the module under certain space and show under certain, but I am not able to get it worked properly.

Here, I want to disable the country folder custom module if we are in space other than the document library space, but if I apply the custom evaluator it seems to hide it everywhere


Copying my custom evalutator and the webscript. Please help me out if anyone has any suggestion.

Hello,

I am still not able to resolve the issue. Can anyone please help me out ???

Hello,

I'm also trying to conditionnally display elements in the "Create" menu and have been confronted to the same issue as yours. Indeed, everything is hidden. My evaluatoris called several times and for one item only, the condition is evaluated successfully but the menu item isn't displayed.

Have you find a solution?

Thanks
