Attached HTML file generates three of the following type of errors (one for each select element): Error: uncaught exception: [Exception... "Failure" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: reserve.html :: <TOP_LEVEL> :: line XXX" data: no] The line numbers I get are 253, 283, and 302. These numbers DO NOT make any sense to me; the lines don't contain the same kind of code, and the last one isn't even in the page (there are only 301 lines!). The code is intended to generate select boxes for Month, Day, and Time, based on the current date. This page works on Netscape 4.76, Netscape 6.1, Mozilla prior to 0.9.4, and IE5+. In Mozilla 0.9.4 the option elements were generated without a problem, but the select was set to the second item in the list instead of the first. Now in 0.9.5 the lists don't generate at all.
hey jkeiser, how's this on the branch? :) Looks like a possible dup of everyone's favorite JS in select bug...
I agree; reassigning to HTML Form Controls. The issue described here is a dupe of bug 100511 Sample of the HTML here: <select> <script> with (document) { for (i = 0; i < monthsLength; i++) { writeln('<OPTION>' + monthList[i]); } writeln('</SELECT>'); etc. etc.

The report here is that "Now in 0.9.5 the lists don't generate at all." In bug 100511 the lists generate, but you can't select any of the items. So I will leave it to others to decide whether or not this bug is a dupe of bug 100511.
This doesn't look like a dup (right on Phil), but it's fixed in bug 34297 patch. I am not sure why it's fixed, and I am kinda scared to find out, so I'll just set this dependent and have done with it.
Depends on: 34297
Fixed with bug 34297 landing.

tested the attachement 53629 on win2000 buildID: 2001-11-08-06-trunk Though I do not see any errors , I noticed the following: 1. I pull down the month select control and make a selection 2. I do not see my new selection showing in the select box - nor do I see the date select box changing. 3. I click on the month select pull down once again 4. The selection I made in step 2 shows up and the date select control also populates the new dates. This works fine on IE6.0 I am reopening this bug for further evaluation.

Aha, probably a result of some flushes we removed when getting things performant again. Most likely, in fact, a particular flush that rods has found lacking. Minimizing the browser window and re-opening makes it show up again. CC'ing JST for good measure.

I'm not so sure that this is due to the lack of a flush, it might be fixable by adding more flushes, but that doesn't seem like the right solution to me. When a new option is selected, the select frame should be nitified and it should invalidate whatever needs to be reflown/repainted. A flush would only force something to happen synchronously, but it should *not* fix a problem like this. Maybe I'm blowing smoke here, but that's how I see this...
Removing the fieldset makes this go away. Same symptoms as bug 52975. *** This bug has been marked as a duplicate of 52975 ***

(By the way, adding the flush back in didn't fix it either.)
