Add two expressions with same attribute name (see attached screen shot same-attr-name.PNG). 4. Click OK. Will see an error message is displayed at the left-bottom cornor.

Created attachment 41305 [details] screen shot: two expressions with same attribute name
Created attachment 41306 [details] screen shot: error message is displayed after clicking OK button
Created attachment 41307 [details] screen shot: error is still displayed after correcting the names
currently on custom operator editors, the validation(action) occurs when user selects the Ok button and the validation action sets the error message. in order to achieve message refresh per user action hence validation per user action please make a enhancement ticket.
