For example if you need to change the WebSearch page you can create your own WebSearch page in your own space for example or copy it to a different name. * you could also maintain a list of default XAR pages that you have modified so that you don't overwrite them when importing a new XAR. Last there's a list of pages that you should not reimport (they are mentioned in the installation guide). Of course none of this is perfect and it won't be perfectly till we have finished the new application manager: http://dev.xwiki.org/xwiki/bin/view/Design/ApplicationManager The work for it is going to start in XE 1.8 but since it's a complex thing it'll probably be fully operational only around 1.9 or maybe even 1.10.

You could probably even reuse the diff API to compare the versions. That said what you describe is very similar to the application manager idea we have: http://dev.xwiki.org/xwiki/bin/view/Design/ApplicationManager You are very welcome to help us design it. Thomas Mortagne and Jean- Vincent Drean are the ones who have planned looking into this during the XE 1.8 timeframe. If you have some ideas fire them here for discussion and when agree we can consolidate everything on that page: http://dev.xwiki.org/xwiki/bin/view/Design/ApplicationManager Thanks -Vincent _______________________________________________ users mailing list [email protected] http://lists.xwiki.org/mailman/listinfo/users
