CC Std UI customization problem

Lex

Environment: TS 6.5 SP3 on Win2K server

I've been developing custom solutions using .Net and the CSSDK, but I recently decided to see what could be done by customizing the CC Standard UI. To that end, I made the following modification in portal_custom.xml and rebuilt the toolkit (and everything worked great):
[html]








[/html]
The "New Forms" portlet was moved to the first column and the "How Do I..." portlet was gone. So I had 2 columns with the following portlets:

Column 1
My Workareas
My Favorites
New Forms

Column 2
Search
Tasks
Work in Progress

A couple weeks go by and suddenly this morning instead of 2 columns in the CC Standard interface, there is one column that fills the entire browser window and it consists of only the "My Workareas" and "My Favorites" portlets. I have rebuilt the toolkit countless times. I have reset everything back to normal and attempted to reapply my customizations. Nothing works, I always end up with the 1 column of only the 2 portlets.

I figure I have to be missing something obvious here. Perhaps I'm not using the proper method to move a portlet from one column to another and I just got lucky before. Can anyone shed some light on this? Also, does anyone know where I can find a list of the id values for all the Interwoven supplied portlets? Thanks.

I found an answer to my question. Poking around a bit more on the forums, I found that you have to assign a new id value to the portlet and use the same refid as the original portlet when moving things between columns. It's a mystery to me why this worked fine for the last 2 weeks and then stopped working today, but hopefully this will be a permanent solution.
