Webi Rich Client Null pointer exception error

I'm trying to create a new Webi document based on a duplicate old one that we have been migrated from BOXI 3.1. I make my changes (filters, expressions) without any problem. When I save it (in different folders) and try to reopen it, I get the following error :

An error has occurred

java.lang.NullPointerException at com.sap.webi.ui.action.PageSizeAction.onUpdateUI(PageSizeAction.java:278)

And the document is damaged for good ! but I can open other documents.

I'm on SAP BI 4.1 platform SP3, the server is on 4.1 but native version.

I noticed that .glf is created before getting the error that has the following content :

Please can anybody help me?

Thanks a lot,

Solution

  • First of all, your server and client should always be on the same version. Using a different version on the client than on the server is not supported.

    The error message is referring to an error in the underlying XML representation of the Web Intelligence document.

    You'll have to test if you can replicate the issue using the 4.1 version of the Web Intelligence Rich Client (so without any SP installed).
