Get Filters used in a Webi document

Hi All,

I'd like to know if it's possible to get the filters used in a webi document using SDK.

=> I'm not talking about Query condition here, but simple filters put manually on a column of a bloc.

Looking throught web documentation, I found elements... I assume I have to :

- select my webi documents :

      IInfoObjects webiDocs = infoStore.query(my_query);

      IInfoObject webiDoc= (IInfoObject)webiDocs.get(id);

      ...

- create a webi instance

    DocumentInstance webiInst =boReportEngine.openDocument(webiDoc.getID());

     ...

But after that, I'm stuck.

I found on sdk documentation reference to classes like ReportBlock, ReportElement, .., but I don't know how tu use it, and I'm not even sure that this is the right way...

If someone can help to achieve this, that would be great !

Thanks,

David
