Re: inmethod custom PagingToolbar with dropdownchoice for setting rows not working correctly

[nino martinez wael <ni...@gmail.com>]

I've had some strange things to, as the "delay" in choice you mentioned.
However in my case I had two grids(master/detail) on the same page, my
workaround was to create a new instance of the failing grid.. It had
something todo with a problem with datasources but I dont remember the
details now.
