Better solution to discover drop location?

[maxogm]

Hello, I work on one page which should have drag and drop support.

I see example from Richfaces live demo, and I made page... but I'm dynamically loading position in which to drop components...

And all drop positions use same dropListener

dropListener="#{packageManagementBean.processDrop}"

Now, I this situation I do not now how to discover where I drop(on which location I drop)?

I try to discover location using:

<a4j:support event="onmouseup" action="#{packageManagementBean.setCurrentDropLocation}">
        <f:setPropertyActionListener value="#{qwe.qweID}" target="#{packageManagementBean.currentDropLocation}" />
</a4j:support>

and this is working, but I try to find better solution...
