Yii integration in joomla

Hello,

I’m trying to integrate with joomla yii, but I have problems with .htaccess




RewriteEngine on


RewriteRule yiimodule \ .shtml $ /index.php?option=com_jumi&fileid=15&yiiPath=$1 [ L ]

 

Yiimodule RewriteRule ^ / ( [A - z_0-9 / ] + ) \ . Shtml $ /index.php?option=com_jumi&fileid=15&yiiPath=$1 [ L ]



In practice gives me the error:

error 500

Undefined index: yiiPath

but basically it is because with the .htaccess fails to make the redirect.

I state that I installed jumi following the guide:

http://www.yiiframework.com/wiki/137/include-yii-framework-in-a-joomla-module/

and if comments




 return $ _GET [ ' yiiPath ' ] ;



by file JHttpRequest works the first menu entry , after which the system can not handle the redirect.
