Hi,

A 3.1.1 site that I built for a customer is having some problems.  I am getting the error message below when logged-on as admin.  I am getting this error with a number of modules on the site.  The example below is the error message with the announcements module.

I am the only user with host or admin provilidges on this site - and there have been no modules added - or any content changes for that matter - for about a month...

Any idea what could be causing this error:


DotNetNuke.Services.Exceptions.ModuleLoadException: Method not found: System.Collections.IList System.ComponentModel.IListSource.GEtList(). ---> System.MissingMethodException: Method not found: System.Collections.IList System.ComponentModel.IListSource.GEtList(). at System.Web.UI.DataSourceHelper.GetResolvedDataSource(Object dataSource, String dataMember) at System.Web.UI.WebControls.DataList.CreateControlHierarchy(Boolean useDataSource) at System.Web.UI.WebControls.BaseDataList.OnDataBinding(EventArgs e) at System.Web.UI.WebControls.BaseDataList.DataBind() at DotNetNuke.Modules.Announcements.Announcements.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

***********

Also, when logged in as admin, I get this error just below the admin tool bar...

DotNetNuke.Services.Exceptions.ModuleLoadException: Method not found: System.Collections.IList System.ComponentModel.IListSource.GEtList(). ---> System.MissingMethodException: Method not found: System.Collections.IList System.ComponentModel.IListSource.GEtList(). at System.Web.UI.DataSourceHelper.GetResolvedDataSource(Object dataSource, String dataMember) at System.Web.UI.WebControls.ListControl.OnDataBinding(EventArgs e) at System.Web.UI.Control.DataBind() at DotNetNuke.UI.ControlPanels.IconBar.BindData() at DotNetNuke.UI.ControlPanels.IconBar.Page_Load(Object sender, EventArgs e) --- End of inner exception stack trace ---

Do you have the right version (1.1) of the framework installed?  Also, I'm noticing the "IListSource.GEtList()"  This is odd.  Anyone know what could be causing that?

The site is hosted at WH4L - I've opened a support ticket with them...

It seems that all modules that call  System.Collections.IList System.ComponentModel.IListSource.GEtList() are throwing an error.  It is causing me some major grief at www.gwaggolf.com.

I agree with you - it certainly seems to have something to do with the .Net framework - not DNN.  I'm just about at the end of my rope with WH4L - this is the latest in a long list of problems I've had with them.  Hopefully they will be of some assistance in fixing this problem.

Have you by any chance changed the control bar from the standard to the classic?
I have noticed that if you do this, the skins that have the control panel in the skin throw errors since the classic toolbar doesnt' use those settings.

hmm.. did i make sense there.. I hope so

Hi Nina,

I didn't change any settings - I'm getting this error with a number of modules, including Catalook store - in each instance, the error is thrown when System.Collections.IList System.ComponentModel.IListSource.GEtList() is called by the module ...
