#1094: Mapguide flexible viewer too slow

-----------------------+----------------------------------------------------
when using mapguide and flexible layouts - this
is very slow (legend widget) and IE7 just freeze for 5-15s ( IE8 also bad,
FireFox is little better) because of huge Java Script work (100% of client
processor).
This is problem on client with Javascript code ( method UpdateLayer()
called so many times ). The server side is ready and works fine!
Our enterprise project is approx 150 layers sorted in tree, the layers
have legends
with less than 5 styles, only 20 layers has legends with 20 styles.
It has beed combined to minimum number of layers according the customer.
The problem is, that flexible layout - every time when changing zoom -
rebuilds completely the layer tree very inefficient way
Is there any solution how to speed up/cache this - or -
some optimalization not to rebuild not-expanded groups/layers etc. ?
