From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.6) Gecko/20011120 BuildID: 20011120 If a text field's blur() method is called from the field's onfocus event, then the onchange event is incorrectly fired. This only occurs the first time the field is focused. Subsequent focusing works fine. Also, IE 6.0 and NN 4.77 work fine. Reproducible: Always Steps to Reproduce: 1. Click on the good field. 2. Click on the bad field. Change event is incorrectly fired. 3. Click on the good field again. 4. Click on the bad field again. Change event is not fired. Actual Results: The change event is incorrectly fired the first time you click on the bad field. The order of clicking is irrelevent to this result. Expected Results: The change event should not be fired unless the field value is actually changed. The only difference between the "Good" field and the "Bad" field is that the "Bad" field calls blur() in it's onfocus event.

Confirmed on mozilla0.9.6 win2k. Nice testcase :-)

I'd guess the problem is that we don't set the internal initial value (which we use for comparison to determine when to fire change events) until the first focus event finishes firing. This may be fixed by the event grouping rewrite going on for 0.9.9. Marking into that milestone for later testing.

124990 and its associated bugs is not quite ready for checkin for 0.9.9. Maintaining high priority and moving to 1.0 for completion and further testing.

topembed- per EDT triage. Joki, please let us know current status.

Greg, is this still an issue?

A test case that I think meets the original poster's criteria.

I couldn't reproduce this, using the test case I uploaded, which presumes the "good" field is the one that has a change handler and a focus handler that calls blur(), and the "bad" field is the one with no handlers. Running on Mozilla: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.7.12) Gecko/20050915 works as expected. The change handler is never fired. Running on Firefox: Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.8.0.1) Gecko/20060111 Firefox/1.5.0.1 throws this exception: [Exception... "'Permission denied to set property XULElement.selectedIndex' when calling method: [nsIAutoCompletePopup::selectedIndex]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame :: file:///C:/var/clients/Bug112025-testcase.html :: anonymous :: line 12" data: no] on the line of code where blur() is called. This is a different bug than originally described, and hopefully reported elsewhere.

wfm. mats.palmgren@bredband.net, it's your duplicate?! Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a2pre) Gecko/20070107 Minefield/3.0a2pre

WFM, Mozilla/5.0 (X11; U; Linux i686 (x86_64); en-US; rv:1.9a2pre) Gecko/20070107 SeaMonkey/1.5a It also works in Firefox 1.5.0.9 and 2.0.0.1 on Linux so it was fixed earlier than bug 265047. -> WORKSFORME
