[Dojo-interest] this.store is undefined

[Dustin Machi]

Its hard to say what the correct answer is without knowing where the  
store is availalbe.  If it was declared globally, then you can just  
access store.getValue().  You could also pass it into itemAccept using  
partial (or hitch)...something like htis:

checkItemAcceptance: dojo.partial(itemAccept, store),

then your itemAccept method would look like:

function itemAccept(store, target, source) {
	/* use store in here */
}
