BPM Inbox not displayed, gives Javascript error

[Qualiture]

Hi,

I am trying to open the BPM Inbox via https://<host>:<port>/bpminbox, but it throws a Javascript error:

Uncaught TypeError: Cannot read property 'dataServices' of undefined in ODataMetadata.js:13

If I remove the roles UnifiedInboxUserRole and com.sap.bpem.Enduser, the BPM Inbox is shown fine, but it states correctly I don't have the appropriate roles.

Have I missed some configuration? The standard UWL works just fine

your server version? what kind of browser you are using?

[Qualiture]

Totally forgotten about that, apologies!

We're on NW 7.31 SP8, using Google Chrome 33.0.1750

[junwu]

same error here, i remembered it was working

i deployed the latest patch for sp8, still same error..

Hi Jun, thanks for the reply, apparently it seems the issue is not limited to our environment then.

I'll file a customer message to SAP

[junwu]

for my system, it was working after sp8 installation.

our developer patched the UI5 library to patch15, then it stopped working, i think.

how about your case?

[junwu]

i restarted the server, it seems to be functional in the morning

now we had some network issue, it is not working again.

Thanks for the update Jun, seems like the BPM Inbox is pretty buggy in SP8....

In the meantime, I'll resort to the good ol' trusted UWL then 😉

can you check the default trace of the server for errors?

Hi Christian,

In the defaultTrace the only hint is :

WARNING: Interceptor for {http://odata4j.sap.com/}BPMEntitiesRequestResourceImpl has thrown exception, unwinding now

com.sap.engine.services.servlets_jsp.server.exceptions.WebIllegalStateException: The stream has already been taken by method [getWriter()].

...but not sure if this is a root cause

Hi Robin,

This looks strange.

Please open an OSS ticket and attach your component info.

Thanks,

Christian
