[ka-Map-users] redraw issue please help

[Jeffrey Reinholz]

We are trying to do a demo for work zone effects with dynamic redraws of 
shape files. Problem is that
the meta info isn't causing ka-map to redraw the tiles dynamically. I 
was curious if anyone else had any
issues with shapefiles and dyamic redraws and what I should look for in 
fixing this issue, if it can be fixed.
I noted that the cached files for this map file where not being updated 
at the interval in the meta data. I have
tried just using this layer alone, and switching to "nocache". It 
appears once the tile is rendered once it is never
rendered again.
