[mapguide-internals] Fwd: Swithing base MgLayerGroup on/off ...fails?

[Ivan Milicevic]

Are you sure that paren.parent.Refresh() triggers refreshing?
 
Try parent.mapFrame.Refresh()
 
Maybe Refres works for "dynamic" layers?
 
I had same problem but I resolved it wit paning 1 point to the left. Never figured out why Refresno() doesn't work.

That's the most intriguing part - as soon as I perform zoom (not pan, since
tiles on base layer group are fully precached), targeted layer group becomes
visible/invisible, as set. I don't get why issuing parent.parent.Refresh();
won't update it in the first place. Is there some other type of JavaScript
refresh function available?
