popup usage in wdDoBeforeNavigation

Hi everybody,

as per WDJ best practice, I want to centralize error and UI message handling in the wdDoBeforeNavigation of the root component controller.

In my project error handling mandatorily includes popup messages. When I try to open a popup in the wdDoBeforeNavigation I get: There must be something wrong, phaseLoopCounter: 21 

Can anyone please explain this error and/or suggest a different approach?

Thanks, points will be awarded, Vincenzo
