[CLOSED] [2.0m2] vanishing x-icon-btn / x-form-invalid-icon
this is the expansion of the topic http://extjs.com/forum/showthread.php?t=68541
after synchronizing with svn, validation icon vanished completely. To force it, I have to add visibility: visible; in the style section. Then it behaves normally. I tried to play around with setting the HideMode's for text fields and containers but without any result...
