prototype's fire() function works fine for me, I tried an alert() and it pops up in IE the way it should,
the only problem i could see in my IE was description not being displayed.
Here's some additional info.
IE8 (version 8.0.6001.18813) (I didn't bothered to check for updates since like ages, so it might not be the latest)
I found the problem for partyId lookup in https://localhost:8443/ordermgr/control/findorders and tested the fix on the same.
Jacques, this is the part i didn't get "if the lookup field is disabled (we use it in a custom application where the name is shown instead and the Id hidden)"
when/why do we disable the lookup field?
I guess I failed to reproduce the problem, Please post the steps.
Thanks & Regards
