[xwiki-devs] duplicated id generation

Hello there, I have been asked to develop something on top of the pdf export facilities on the xwiki. But I run into a small problem: When *generating a pdf with multiple pages*, say all the pages from one space, the ids of elements within the pages get duplicated and the *pdf exportation fails*. i.e.: *Page A* with a title *TheQuickBrownFox...* some text under it and then *page B* with the same title: *TheQuickBrownFox...* with some other text under this. Both will get an auto ID of *TheQuickBrownFox... *Now this doesn't happen for items on the same page since the ID generation mechanism counts all items of the same name and increments it if necessary. But this mechanism does not contemplate cross page duplicated items. To avoid the following error: Property ID "lipsum" (found on "fo:block") previously used; ID values must be unique within a document! (See position 12:39) We thought some changes to the ID generation mechanism could be made: We could* prefix the ID* with the space and page name and this would be a simple elegant solution. Now: Is this the best solution? Will someone point out the best place to do this? If I post a patch with this fix will it be included on the trunk?
