The reason I didn't go down that path, is because it's a checkbox in a column in a table, and I'm using it to do an insert. I didn't want to have to have a separate value for each item, when the majority of them don't even exist yet. I can flush out my model to make sure that there is always a place holder for the xs:boolean, but didn't really want to if there was a simpler way to do it buy just using a checkbox to add and remove the element. Guess I'll have to do it the other way. Why is it that I can put triggers in the column (show/hide) buttons, and the engine knows where I'm coming from, but It doesn't when it's just an xhtml element? it seems like if there was a way to get the id from a repeat or to refer to one, then this would work. I'm just curious more than anything at this point. Anyway, thank you very much for the input (no pun intended).
