Post upgrade, an attachemnt in KM iview not opening.


Dear Experts,

we have portal on 7.0

My client has upgrade from NW7.0 SP 19 to sp28.

since then we are not able to open attachments in the KM navigation iviews.

it says :


An exception occurred during Program execution

when checked in NWA for the logs: we got java.lang.nullpointer exception for CollectionListrelatedResouceRenderer.

i have searched for this kind of issues. it said that restart of server has solved the problems.

but for our case the server restart happens every tuesday.

still its the same.

Please find attached are the screenshot of the error and of the exceptions.

we are unable to resolve why is this error coming?

Please suggest us what to do?

Thanks in advance,
