Question:
Why does CMyAppUi::ProcessCommandParametersL() not seem to get called on Symbian OS v6.x?

Answer:
This can often catch you out when porting code from ER5 to V6.0 or later versions. The function:

TBool CMyAppUi::ProcessCommandParametersL(TApaCommand aCommand,TFileName& aDocumentName,const TDesC& /*aTail*/)

on ER5 must be coded as:

TBool CMyAppUi::ProcessCommandParametersL(TApaCommand aCommand,TFileName& aDocumentName,const TDesC8& /*aTail*/)

on V6.0 or later versions, otherwise it will not get called.
