I have a big problem with FormPanel. After second time I try to access the FormPanel after trying to scroll panel down it still go back to top.
I did some research, it looks like div of class 'x-scroller-parent' don't get required css width and height properties. After manually editing html to add properties, or resize screen scroll starts to work correctly
I sincerely hope that some of you know solution to this problem, as it seems to be bug with sencha itself, and not a code.
