4008 : RuntimeError, Message: Layout cycle detected. Layout could not complete.

[Alexey Oyun]

When I try to add 3rd gauge control to the page I get this error:

4008 : RuntimeError, Message: Layout cycle detected. Layout could not complete.

And if I take away one of those three gauge controls page loads fine.

Here is markup, no code behind. I have used dll from RadControls_for_Silverlight_4_2010_1_0422_TRIAL_hotfix
Thanks.

Hi Guys,

This issue was fixed after the Q1.SP1 version of the control. To get things working, please, upgrade to the latest internal build available in your customer accounts.
