what am i doing?
i want a modal-confirmation: user clicks on button, confirmation "do you really want to...?", user clicks "yes", this click unbinds the original click-handler and clicks the button again (which should cause a submit).
what/why is not working?
indeed you need a special case. this demo won't work, unless you set modal: false.
interesting to mention: the original handler (onclick="FooMethod();") is called in modal and non-modal dialog.
can anybody help me out?
thanks in advance!
