Hi Michael,
I 've just tested a brand new DNN3.3. installation and added an IFrame module to a new page. I did some basic setup, save it and the wanted page shows up inside the IFrame.
Now I have added a QueryString parameter. It doesnot matter which one i take though I get the following error message:
Error: IFrame is currently unavailable.
DotNetNuke.Services.Exceptions.ModuleLoadException: ? ---> System.MissingMethodException: ? at DotNetNuke.Modules.IFrame.Domain.IFrameParameter.GetValue() at DotNetNuke.Modules.IFrame.Domain.IFrameParameter.ToString() at DotNetNuke.Modules.IFrame.Domain.IFrameParameterCollection.ToString() at DotNetNuke.Modules.IFrame.IFrame.Page_Load(Object sender, EventArgs e)
PS: You should test your module with IE too. The dropdownbox for the value has a length of one charcter if no other querystring is added before.
