Hi Marc,
Feature merged, thanks.
A possible improvement: when you create a table having a VARCHAR column and you forget the length, you get a nice "This is not a number" message.
There is no such nice message when changing a column, so you get an error that does not point to the real problem.
I fixed this issue for the ajax enabled scenario by using the "*
checkTableEditForm()*" function and pushed the code to the repo. But for non ajax scenario I didn't handled yet. For applying this in the non ajax behavior I have to move the "*$("#append_fields_form input[name=do_save_data]").live('click')*" action to functions.js file in order to make accessible at the tbl_alter.php file. Is it okay to have this action in functions.js file and the other actions related to change option in tbl_structure.js file. If it is okay I'll change that. Thank you.
Regards, Thilanka.
