Go To StackoverFlow.com


I am new to flex and i am trying to run the code for flex drawing application example given at following path: http://www.flashcomguru.com/components/flex_whiteboard/whiteboard_demo/srcview/index.html

But I get the following error at the compile time:

''Unable to locate specified base class 'Whiteboard.WhiteboardManager' for component class 'Whiteboard.Whiteboard'.''

Please someone suggest me that why it is coming and how i can overcome this.I am using Flash player version 10 and flex 3.0 sdk for the project. Please help. Thanks in advance.

You need to include the WhiteBoard.swc library in your project. If you're using Eclipse/Flex Builder go to project properties -> flex build path -> library path -> add swc. Or moving it to the libs folder should be enough. The sources for the component are not included in that demo as it is not a free component. I didn't see a demo version either, so unless you buy it, you probably won't be able to run those sources locally.

Sounds to me like your source paths aren't set up correctly. Have a read of this article to see how source paths are set up

Hang on... looking at the source, that class is missing. You may need to email the guy that created it to see if he can send it to you - James Hay 2009-06-16 08:38
