NullPointerException on Web Dynpro PageBuilder

[Former Member]

We're using Portal 7.01 SP11. We sporadically get this exception in the logs. Anybody know what this is?

Exception occured during processing of Web Dynpro application sap.com/pb/PageBuilder. The causing exception is nested.

if you don't have error in the screen, just leave it....

It is reportedly causing "Portal Runtime error" on the browser.

Hi,

Seems to an error from  pagebuilder which is a portal component (not related to applicaiton). May be you can report this with SAP.

how your WD application is integrated in portal ? may be looking to details who this is integrated can give some ideas to resolve the issue
