I am attempting to upgrade an old (custom) component for Joomla! 2.5 to 3.0, and I've been having issues with a few things, mainly JToolbar.
When I click on any button, I get this in my error console:
TypeError: null is not an object (evaluating 'n.task') (submitform — core.js:1:213)
If I just press return/enter in the form, it refreshes the page and doesn't save any information. I already went through and renamed JElement to JFormField, replaced var properties with
public $type, and switched all JController/Model/etc. to their Legacy versions.
I tried looking around for articles, lists, and tutorials but I couldn't find anything at all about migrating actual components from 2.5 to 3 other than a small list of incompatibilities and a brief mention of
J*Legacy classes and the changes that I mentioned. Everything else that comes up is all about just migrating actual installations from 2.5 to 3.
How can I get it to work?
