Hi Fabio, Now I'm working on the costume implementation of the IDocumentPartitioner which uses the XDOM parser. I have also look at the FastPartitioner implementation in-oder to get understand how the partitioning work. As far as I can understand, to register partitions with the IDocument, requires the offset and the length of each token retured by the partitione. But currently that information is not avalable in the Blocks returend by the parser. WDUT ? Is ther any other way of doing this ? I need help on this I aslo look try to run the org.xwiki.xdomexplorer you gave to me.After mvn compile and run the project as a eclipse plugin it gives a errer sayying Error opening the editor. org.xwiki.xdomexplorer.editors.XWikiEditor.I'm working on Eclipce JEE 3.3.2 version.Should I need to run this in different eclipse package ?
