Question

I am encountering this problem when trying to upgrade a legacy project from Flex SDK 3.3 to Flex SDK 3.6

The error gets thrown at runtime only, at compile time there is no issue.

My hunch is that it has something to do with DataVisualization components.

Though all datavisualization swc’s are in place, I am still getting this error.

Even did a fresh download of the 3.6 SDK, overlayed the 3.6 DataVisualization swc’s, still the same thing.

Using Flash Builder 4.6 Premium

Has anyone encountered this before?

Any help on this matter would be more than welcome.

Cheers

This issue was caused by using an incompatible flexlib.swc library.

Updating flexlib from version 1.9 to 2.5 solved the issue.
