Hi Vincent, I do not really understand how I am supposed to reproduce this bug. How do you create an empty table ? What do you mean by "with hidden columns by default" ? Regards, Nicolas Guyomar
Created attachment 196198 [details] A plugin to open an empty table with hidden columns by default (1) I, Vincent Lorenzo, wrote 100% of the code I've provided. (2) This code contains no cryptography (3) I have the right to contribute the code to Eclipse. (4) I contribute the content under the EPL.
(In reply to comment #2) This plugin allows to reproduce this bug : Steps to reproduce : 1/ Create an empty table, with the action "Open bug example tabular editor" 2/ Drop an EClass in the table (all its columns are hidden by the customization of my example) 3/ Delete the line with your element 4/ the hidden columns appears and I get an exception

We can then mark this bug has fixed.
This bug can be closed.
