[TYPO3-mvc] Error in Domain model

[Michael Knoll]

Hi Sebastian et al.,

some weeks ago I wrote about a bug in Extbase domain model and also 
opened up a issue on forge. You asked me to send you the extension, 
which I did now. You can download the code via

http://dl.dropbox.com/u/4247076/yag.zip

I stripped everything besides the necessery controllers and domain models.

It's easy to install. Open up a new page, and make a new root TS - 
template. Insert standalone template as static template and you're done.

The error occurs, if you create sample data, reload the index page, edit 
created album and then click "save".

#1251730701: The value must be of type "Tx_Yag_Domain_Model_Album", but 
was of type "NULL".

A longer description of my problems can be found on:

http://forge.typo3.org/issues/12681

and

http://forge.typo3.org/issues/9270

The problem in the second issue still occurs for me - you should see it, 
if the first problem is solved :-)

I hope, you can help me out. I don't know what to do anymore as I tried 
everything...

Hopefully it's not just a stupid typo or something as I do not wish to 
waste your time.

Thanks a lot for your help!

Greetings

Michael
