doLayout() on Panel makes app crash
I'm using ExtJS Portal for my application. When I try to move or resize portlets, I call myContainer.doLayout(); to force the container to refresh its children (my portlets). But sometimes this call makes my app crash, with no error on Firebug.
The content of my portlets (graphic charts, pie charts, bar charts...) are not refreshed any more and for exemple when I resize a portlet, it's content is not re-arranged to fit the layout. I hope you understand me.
Why does this behaviour happen ?
Thanks in advance
