I have a big problem while completing my application with series60 sdk relating BIO messages and ProcessCommandParametersL() function.

My application is associated, through a BIF (dll) file, with a specific BIO Message.
When I try to open the BIO Message from INBOX my application starts to execute but it is not called ProcessCommandParametersL() function in CMyAppUi class. I can't retrieve TMsvId of the related message and, when I close my application the message application is blocked.

Can you help me??
