Strange Behaviour of Classic Reports in the RTC after hotfixes

This week I got an email from Thijs den Hartog that he was experiencing weird behaviouor of classic reports after doing dome updates of the binaries of Dynamics NAV.

Also this week I read an announcement on the NAV Teamblog that they introduced a new feature called Metadata versions since updating the binaries require a recompile of all objects.

Dit you think I was smart enough to link these two?

Eh, no...

But after another email from Jorrit Mertens that they found out that their solution was a recompile I did.

So this seems to me an important update for all RTC users.

Just a sidestep: At my RTC implementations I do not use classic reports anymore and since Microsoft reccomends not implementing hotfixes unless you explicitly eperience the problem that the hotfix describes I recommend both.

1. Always convert your reprorts to RDLC, it is really not that complicated once you get the hang of it. Its actually fun.
2. Never implement Hotfixes unless you really need them. 

Thanks Jorrit and Thijs for allowing me to share this valuable information.

Enjoy your sundays.
