[TYPO3-project-realty] Realty and another language

[Murat]

Hi,
i would like to add turkish to Realty Manager.
Extension is working with German and English so far but when I change it 
to turkish it displays :

###REALTY_ITEMS###
###LINKS_TO_RESULT_PAGES###

I added the labels in  turkish in pi1/locallang.xml as a
<languageKey index="tr" type="array">
<label index="realty.pi_flexform.sheet_general">Genel</label>
.
.
.


.

.

<label index="message_invalidImage_informal">
Bu resim veri bankamızda kullanıma açık değil. Lütfen yazdıgınız adresi 
kontrol ediniz. Eğer bu sayfaya bir linkı takip ederek geldiyseniz, link 
yanlış ya da eski olabilir
</label>

</languageKey>

What am i doing wrong? or what should i do in order to have it working 
also for turkish.
thanks in advance
Murat
