[reSIProcate] DUM: handling createAppDialogSet() failure

[Dmitry Semyonov]

Hello.

It is assumed that createAppDialogSet() always returns "good" pointer. 
Should an exception be thrown from overridden createAppDialogSet() 
function in case when dialog set creation fails by some reason?

The same question applies to createAppDialog().
TIA.
