[TYPO3-realty] sort funtion doesent work

[Schmitz]

Hello 

First: thanks for this great extension.

It is not possible to sort in FE, and also the search dosent work.

I worked with this extension and an older version of realty.1 year ago and the sortfunction worked at that time.
There is no error-warning, I checked all typoscript and all flexforms, have read three times the sxw-File. I dont know, what to do.

All other works fine.
I have installed  Realty manager 0.4.3 and oelib 0.6.5
