Help with setting properties

Hi all! So I'm trying to replace the properties of a style in a couple
places in my GSoC code. It seems that recently I am removing the
properties from the style rather than replacing them. This happens
whether I redefine a style or "edit" one (which right now just calls
simplifyProperties). Here's the code I'm using - I call
"setAllProperties" which I added to remove duplicated code in my branch.
http://abisource.com/viewvc/abiword/branches/gsoc2008styles/src/text/ptbl/xp/pd_Style.cpp?view=markup
Start at line 388 or so.

Here's an example of what happens after I save a document after
simplifying a style (by clicking Edit in the Stylist)

The desired result would include

followedby="Current Settings" props="font-family:Tourist Trap"/>

Thanks for any help you might be able to provide!
