Loaded this initially against earlier topic but forgot the code tags and seems to have mucked up page so sorry about that. Anyway I was trying to say that I have a similar issue but does not seem to be related to commas. Have simplified to the extreme but still no joy. Have been testing up until now in firefox and works fine, but no joy in ie7.
My simplied cutom class is seen below stored in file struture dojoroot/my/form/ButtonCtrl.js where dojo.js is in dojoroot/dojo:
dojo.provide("my.form.ButtonCtrl");
dojo.require("dijit.form.Button");
