[TYPO3-english] Extbase - All properties except UID are null

[Alexander Dorn]

Hello,

I am developing an extbase extension with TYPO3 6.1.

Sometimes - I can not reproduce the error - all properties of the domain objects are set to null when fetched from the repository. 

The query is executed correctly because I get the resultset that i expect - only the values are missing.
google found just one related thread: http://stackoverflow.com/questions/17803694/when-fetching-a-model-all-properties-are-null-except-for-uid
But in my case the bug occurs rarely.

Normally an object looks like this.

uid:  			1
title: 			Some title 
description: 	A longer text that describes the Object
image:		path/to/image
...

When the bug occurs it looks like this:

uid:			1
title: 			null
description:	null
image: 		null
...

The model contains about 15 properties and in 99% data is fetched correctly.  But the one percent is driving me nuts as I don't have a clue where to start research.

I assume that the property mapper is not able to map the properties correctly.

Any help is appreciated.

Thank you 
Regards Alexander
