When you place the Editor control inside a View control which is inside a MultiView control, VS designer will throw an exception and will not render the entire MultiView which is a serious problem for me.
The exception details are as follows:
"Error Rendering Control
An unhnandled exception has occurred.
The control collection cannot be modified during DataBind, Init, Load, PreRender, or Unload phases"
As far as I know this issue is more VS related rather than bad coding/bug inside the controls which causes the exception, but unfortunately there is no fix for this issue by Microsoft.
When this happened to me with one custom control I had, a workaround I found to keep using the designer was to put a try catch on those events that it was overriding, in my case OnInit and PreRender.
That way the control would still render in designer, and work properly in my web site.
Since I don't have access to CuteEditor source, I cannot do the same workaround for it so I need it to be fixed in some way as soon as possible.
