SWZ, RSL and Flexmojos Build Setup
With default Flexmojo build setup your clients may easily fall into .swz load issue. Why clients? Because you already have .swz files cached in your player but they dont. Sure, you can turn off caching easily. The issue is textLayout and osmf uses a different version numbering and .swz location than the rest of the flex sdk .swzs. The exception by flex application may look something like this:
