340465 - applet is initialized and reinitialized multiple times when frames' sizes are adjusted

Status: RESOLVED DUPLICATE of bug 90268

(Core Graveyard :: Plug-ins, defect)

Description

[Pawel Zieminski]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8) Gecko/20051111 Firefox/1.5
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8) Gecko/20051111 Firefox/1.5

This can be reproduced using the attached sample (as soon as I figure out how to attach it).

Reproducible: Always

Steps to Reproduce:
1. Unzip the attached sample into a directory 
2. Open start.html in the browser. Open java console and turn on tracing to be able to monitor applet events (trace level 3 is fine)
3. Click on the link 'click here to start'

Actual Results:  
Note the multiple instance of the applet are created. Clicking the 'resize' button on the page with the embedded applet cause the applet to be reinitialized, and multiple applet instance to be created as well. Sometimes, after a few resizes of the frames the applet fails to initialize at all.

Expected Results:  
Single applet instance is initialized upon loading of test.html, and frame resizes do not cause the applet to get reinitialized. This used to work in Firefox 1.0, and works correctly in Mozilla 1.7.13.

This is reproducible on Firefox 1.5.0.4 on Windows 2003 Server, Fedora Core 5, Mac OS X 10.3.9.

Forgot to add that this is also reproducible with that latest build
Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.9a1) Gecko/20060605 Minefield/3.0a1

This has something to do with changing the 'scrolling' attribute on each child frame. Commenting out line 106 in myscript.js (in the sample attached) fixes the behavior.

bz, does changing the scrolling attribute cause a reframe?

Comment 5

[Pawel Zieminski]

It seems only when it's changed while changing widths of frames triggers this. Changing this attribute alone works fine.

Comment 6

[Boris Zbarsky [:bzbarsky]]

Yes, since it's mapped to the CSS "overflow" properties.
