[TYPO3-mvc] Extbase label translator plugin

[Rayuth You (Yuth)]

Hi list

Using extbase 1.3.0 I got a problem when I wanna get label translator 
from other plugin. I used 
Tx_Extbase_Utility_Localization::translate($key, $myExtKey);
But What I noticed is $myExtKey because that extension has 4 plugins 
(pi1, pi2, pi3, and pi4).

I wanna get label from pi4, Any body has any hint?

Regards,
Rayuth
