using libraries in models

[eluser]crumpet[/eluser]
hmm i feel really stupid but it didn't seem to work .. i've rewritten the code since then to not use libraries in the model but I tested it pretty throughly... i wasn't autoloading any of hte libraries/models so i don't think thats a problem. And though originally I was loading the library in the constructor of the model I tried loading it in the same function as the library function is called. And yes the library works perfectly in a controller and i copy pasted the code for loading the library there into the model.

So I just tested it using bare bones functions and that seemed to work so it must have been an error in my code elsewhere...really strange though because i'm sure i tested it this way before
thanks everyone for your help I will post again if I figure out what the problem was exactly.
