Found the problem...we had some code in a related .script that was firing after the page had fully loaded. This script code modified some text field values (blanked them out if a related select field was set to a certain value) after the dirtyFormWarning had already taken its 'hash' value of the form. When the user tried leaving the page the original form's hash value was now different because the text field was set to blank. Just thought I'd share in case anyone has the same problem going forward.

Subject: [Tacos-devel] DirtyFormWarning firing on clean form
I'm trying to leverage the DirtyFormWarning, but am finding that the warning
dialog box is being displayed even if no changes are being made to the HTML
form. I don't know why this might be happening and tried looking at some of
the resulting HTML/Javascript code to get some better insight. The only thing
that I found strange was that javascript variable 'dirtyFormWarming' was
initially set to true....here's a code snip of the HTML output:
var dirtyFormWarning = true;
function setDirtyFormWarning(enabled) {
dirtyFormWarning = enabled;
}
window.onbeforeunload = function(evt) {
if (dirtyFormWarning) {
var currentFormValue =
dojo.io.encodeForm(dojo.byId("AddDailyPatientForm"));
if (initialFormValue != currentFormValue) {
return "You have unsaved changes.";
}
}
setDirtyFormWarning(true);
};
I would've thought that 'dirtyFormWarning' would've been initialized to
'false'? With it being initialized to 'true' I can see why the warning dialog
is always being displayed w/o the user having done anything. Btw, the
'forceWarning' attribute is not being used (just the 'form' and 'message'
attributes).
Is there any common/typical culprits that cause this behavior? Is there anyway
I can initialize the 'dirtyFormWarning' javascript variable to false? If
there's any help or direction someone can point me in, I'd be very grateful.
Thanks in advance!
