Flex compiler's artificial intelligence doesn't link all the imported classes unless those are refered somewhere in the code. So its necessary to refer the class somewhere in the application. So what i did was I declared a dummy variable var frm1:Form1 = null; var frm2:Form2 = null; and it worked like a magic now dynamic creation works like a charm. Please refer to this URL http://jwopitz.wordpress.com/2008/02/21/getdefinitionbyname-trick/ its claimed that this is a elegant way of achieving same result but I could not understand it properly. If possible can u elaborate the technique he has used in ur next post. > > But I am still more confused about your problem. Let's try again.

If possible please comment on what I have done whether its a best practice or not and suggest better alternative. Thanks for interest shown and time spent on me. I feel that I have got another good friend now. Best regards RAJA
RE: [flexcoders] Re: Create mxml custom component in a actionscript event handler
The compiler compiles the function regardless of whether it is ever called, If you reference a class that it cannot find it will error. No, if you are using normal classes, then you must have a reference to that class in order for it to be linked in at compile. This is one of the problems the Modules are intended to address. Note, the reference can simply be a variable declaration typed as the class. But I am still more confused about your problem. Let's try again. Can you instantiate Form1 if you wanted to?

I am not understanding what difference it makes when I comment out a unused function. Well to best my guess when Form1 is referred explicitly in onItemClick function the mxml class Form1 is being linked but when I comment onItemClick function Form1 Class is not being linked. Is there any way to Link this Form1 in application so that its available for dynamic Instantiation i.e. without having any explicit reference in main application. Thanks and Best Regards Raja

Ok, what happens if you just try to instantiate a Form1? If the code is not finding this class then you certainly can't proceed.

How a import statement if Form1 and Form2 are in same source directory that of application ? The output directory is bin-debug within the source directory. Project directory is same as source directory. BTW if comments are removed how the code works, what happens when comments are put can u shed some light on these point ? Thanks and Best Regards Raja
