Yes, I will explain what happened.
1 RadEntry: e-mail keyboard, it's working fine
2 RadEntry, first read-only and the second with the effect attached, working fine.
1 RadEntry with effect, not working fine, still showing the default Number keyboard
On third view it didn't hit the breakpoint, I didn't understand why
I am using these entries in a control that I created and exposed the properties and bindable properties.
Unfortunately I can't share my code, since it belongs to my company, but I will try to reproduce it this weekend when I get home and then I'll share.
