It's a know issue and solved in WPF 4.0, i've got it working as well.
The blog from lhotka: http://www.lhotka.net/weblog/WPF40DataBindingFix.aspx

But the problem is that we have all our controls on UpdateSourceTrigger="PropertyChanged".
Did anyone tried this in WPF 4.0 if it'll work having it on PropertyChanged?

I can't get it to work in 3.5 without changing the UpdateSourceTrigger to OnLostFocus :(

The official workaround for this problem, as specified by Microsoft, is to put a value converter on every binding. That's why the IdentityConverter exists in CSLA .NET - it is a converter you can use when you otherwise really wouldn't need one.

I know, but that is only working with setting UpdateSourceTrigger to OnLostFocus and our applications are having the UpdateSourceTrigger set to PropertyChanged.

I see, in that case I don't know of an answer.
