We are using the 1.4 framework with the MM Infragistics 1.3 web controls and when we try to use any of the mm infragistics controls we get a run time error of

Field not found: OakLeaf.MM.Main.mmAppBase.IsRunning

with the following stack trace

[MissingFieldException: Field not found: OakLeaf.MM.Main.mmAppBase.IsRunning.]
OakLeaf.MM.Main.Web.UI.WebControls.Infragistics.mmUltraWebGrid.OnPreRender(EventArgs e) +0
System.Web.UI.Control.PreRenderRecursiveInternal()
System.Web.UI.Control.PreRenderRecursiveInternal()
System.Web.UI.Control.PreRenderRecursiveInternal()
System.Web.UI.Page.ProcessRequestMain()

I loaded up the framework source code for MM infragistics and stepped through the events of the mmUltraWebGrid.cs where the trace shows the error but could not step into the OnPreRender method. I also put a stop in the OnInit and using the command window tested the mmAppBase.IsRunning and it was working there. This error occurs on any page that has a MM Infragistics control on it.
