Ja_tiny_mce Help Needed

Hi

I have jrails plugin installed.
I am using ja_tiny_mce plugin and it works like charm for me.

Image upload works fine.

I wanted to do media upload also,

so i what i did downloaded advmedia plugin and putted it in tiny_mce plugins directory.

also i added it in appconfig options file.

But, its not working its giving me error.

tinyMCE.importPluginLanguagePack is not a function

tinyMCE.importPluginLanguagePack(‘advmedia’);

Same, case for youtube plugin also…

Your help really appreciated.

Thanks & Regards,

Sandip
