PopupDateField TextChangeListener?

I have a report-launching dialog with date parameters and a link to the report (external with query parameters). The problem is that if the user types in a date and clicks the report link, both the ValueChange and Blur listeners are late in changing the link URL parameters and the PopupDateField is in the wrong hierarchy to have a TextChangeListener. Any workaround?

Thank in advance,

This is of course a problem since the blur isn't fast enough and the link is already done when you click it. I might be able to work around it by generating the link on the onclick handler but using JS to dig out the values from the UI is never pretty.
