Why ParameterizableWebPart get returned as an ErrorWebPart?

Question

I'm using WSS3.0 API to get all the webparts in an ASPX page.
The following is my code:

                SPFile page = web.GetFile(pageGuid);

                SPLimitedWebPartManager wpm = page.GetLimitedWebPartManager(PersonalizationScope.Shared);
                WebPartFactory factory = new WebPartFactory();
                foreach (System.Web.UI.WebControls.WebParts.WebPart webpart in wpm.WebParts)
                {
                    //Some other logic
                }

This code works fine for most of the web part. But for ParameterizableWebPart, it always returns an ErrorWebPart.

The page is correctly configured, because I can view all the reports in explorer.

Have you ever encounter this problem? Or there is something wrong with my code?

Any comments are appreciated. Thanks.

Answer 1

PerformancePoint web parts are different animals than regular web parts. There's a great post on technet talking about this, with links to more information. They were built from the ground-up chock full of AJAXy goodness. This might be why you're getting an error when you hit that web part.

This article states, that the SPLimitedWebPartManager will return ErrorWebParts instead of some WebParts, when not called from a web request. Maybe this is the problem in your case?
