A htmlb:form for each htmlb:tabStripItem ?

Question

I have a BSP-page with a htmlb:tabStrip with several tabStripItems that are rather large.
I'd like to have a htmlb:form for each tabStripItem or even for parts of the Items.
This is not possible, right?
If I use onSelect of the tabStripItems and there is no htmlb:form around the entire tabStrip, I get a shortdump. And if there has to be a from around the entire tabStrip. I cannot place additional forms inside the tabStrip.

yes, there seems to be a (quite dirty) JavsScript-Hack.
I just placed a small form somewhere in the code
<htmlb:form id = "hidden_submitter_form"
            method = "POST" >
<DIV style="display:none;">
  <htmlb:inputField id="i1" value="initial"/>
  <htmlb:link id="submit_link" onClick="do_it" text="invisible"/>
</DIV>
</htmlb:form>
And in my tab, instead of having an onClick, I have a button with a onClientClick, that does something like this:
  document.getElementById("i1").value = "some_value";
  document.getElementById("submit_link").click();
So you just copy the values you want to submit into inputFields and then click the link or button with JavaScript. This will fire a serverEvent and only submit the inputFields you need.
This probably only works for IE (haven't tested it), and your still, proposal with subcontrollers is probably more elegant..
