Some odd issues with using the Chart Control inside a wizard...

From: http://social.msdn.microsoft.com/Forums/en-US/MSWinWebChart/thread/1dc4b352-c9a5-49dc-8f35-9b176509faa1#page:2

I don't know if this is the same problem as everyone else has seen (sounds like maybe it's different).

I wrote a page with a chart in it.

I then changed the page to use an asp:Wizard - the chart being in the last step.

After this change, I got the executing error shown below when I reached the last page.

Moving the chart out of the wizard and back into the root of my control removed the error.

However, when I moved the chart back to the last step of the wizard again, the error was cleared....

Somewhat confused at present...
