Re: class method binding problem

Thank you very much for the reply.
Nice to here that there are many ogre3d users around.

The error is a lua run time error. That is what i get when prints the error.

I have identified the problem.
Here I have to provide parameters for the init method. It does not
take default parameters.

It took my around 1 and half day to find that.

What happens now with your Lotus Notes apps - do you make another costly 
upgrade, or settle for being marooned without product support? Time to move
off Lotus Notes and onto the cloud with Force.com, apps are easier to build,
use, and manage than apps on traditional platforms. Sign up for the Lotus 
Notes Migration Kit to learn more. http://p.sf.net/sfu/salesforce-d2d
