Web Dynpro error after migration from 7.00 to 7.40

Hi all!

I have migrated a Web Dynpro for Java application from SAP Netweaver 7.00 to 7.40. Everything worked pretty good except some dependencies. These were fixed now but now we have an error when using the web gui.

We have a reproducable error always at the same location in the application. The error message hints to a view (name = HeaderView) and there at an image object (ID = LEAHeaderImageCenter). I already tried to rename the image object but no success

Some technical information:

- Server: SAP NW 7.40 SP08 (Java only), SAP JVM, Linux SLES 11, Oracle DB

- Browser: Chrome (39xxx), IE 8, FF 33 (alway the same error ...)

Here is the stacktrace:
java.lang.IllegalStateException: IDs for initialization not empty: [NCEF.HeaderView.LEAHeaderImageCenter]
