Can widget Templates (Template.pt) be overridden with jbot, for example from a theme?
Should be possible. If you ask: is there an issue?
I did a quick test (before I left work for the day). It did not work, but maybe did something wrong.
I did a (quick) read of the description and it said:
Any template that is defined as a class-attribute can be overriden using jbot, e.g. those used in views, viewlets and portlets.
So it did not mention widgets, but maybe it is (still) possible
@espenmn Can you show what you've tested and which template you want to override doesn't work? It's a bit vague now for others to respond in detail.
To my theme/template-overrides folder and the changes appeared on my site
Then I added the same file to browser/overrides (and changed it a little) and it also worked.
Then I did the same thing (added to the folders)
But the changes were not 'happening'.
You're going to have to do some deep reading, modifying forms is an interesting and challenging task
Start here, don't skip anything...
