Looks like a bug, where I have to set the action attribute of the form in dom before submitting or there will be no form action assigned and the form post will fail:
does the same in FF and IE, and I'm using the ext-base.js; easy work around but this should probably get fixed so other's don't run into the same thing.
style:'padding:0px 0px 0px 140px;margin:0px 10px 30px 10px',
}] // end inside items array
thx! (Ext is the BEST man)
