[TYPO3-dev] Cache problem with QueryBuilder

[Pascal Querner – MSCG]

Hi,

maybe some cache files could not be written, so check the folders for any misconfigurated permissions.

As a hotfix I would suggest that you auto-clear the cache folder on the filesystem and the necessary database tables.

It would also help to check the deprecation or syslog perhaps. (Or check if the extension "devLog" throws anything regarding this)

Betreff: [TYPO3-dev] Cache problem with QueryBuilder

Hello,

One of my websites is often inaccessible because of an exception occurring in QueryBuilder.

More specifically, the error I get is

> Uncaught TYPO3 Exception: #1327065745: Unsupported or non-existing 
> property name "categories" used in relation matching.

and it occurs when displaying a plugin from roq_newsevent extension, which is adding some fields to the model from news extension. The exception is throw inside the parseComparison function because $typeOfRelation variable is null.

If I flush cache from install tools, the exception no longer occurs. But it come back a few hours later, and I'm not able to determine what is causing it.

I suppose it is related to some cache that becomes corrupted, but I cannot tell if the problem comes from roq_newsevent, news, or extbase. My installation is TYPO3 6.2.11.

Does anybody have an idea of how I could solve this problem?

Thank you,
