[mapguide-users] Reloading runtime map

[Hidekazu Shimaji]

Hello Jim,

I'm sorry again I misraed your mail.
Refreshing after adding a layer is the problem, right?
The Refresh function (Viewer API) worked well in my case, 
and I could not understand what the problem was.

I tried 2 viewers, and found that 
if I use the AJAX viewer, the Refersh function works, 
but if I use the DWF viewer, the Referesh function does not work well.
the legend of the new layer appears, 
but objects of the new layer in the map area would not appear.
After I uncheck the legend and check it again, objects will appear finally.

But this case even seems different from your case.
Sorry I cannot help you, and I hope somebody will help us.
