- | =Flex and ActionScript Error Codes=
| + | GXNBcZ Really appreciate you sharing this article post.Really thank you! Really Cool. |
- | One of the great things about working on the Flex development team is seeing how people create these amazing applications; things you never would have thought possible. However, the flip side of that is that when people are developing things you never would have thought possible, they get errors you never would have thought possible. This page is an attempt to capture and catalog Flex and ActionScript compiler and run-time errors, along with the environment in which they occur, and what it took to fix them.

One common mistake is to accidentally bring in Managers (PopUpManger, DragManager) in a module and use from another module.

- | <li>A code-based workaround is as follows:<br />
| + | |
- | | + | |
- | If connecting to a named LocalConnection "A" fails, you can try setting up a temporary callback LocalConnection and then invoke a send() to connection "A". If the owning instance is running it receives the call to connection "A" and should ping back over the temporary connection and you'll know that the connect failure is legitimate because the owning player instance is running. If you don"t hear back after 5 seconds (magic number) the Player assumes that connection "A" is orphaned and cleans up the shared memory, and at this point you can retry your connect() and it should succeed.

- | <p>Another cause of this error is using managers (or other singletons) within a module before they're loaded by the main application.
