Dialog: iFrame being loaded 3 times in Firefox

Description

When using an iFrame in the div of a dialog, the iFrame is being requested 3 times (instead of once), when the dialog is being displayed. Reproducible in Firefox 3.5 and 3.6. Doesn't happen with Safari.

These multiple requests can have a major impact depending on the page which is being called.

To test, disable all browser caching (use about:config, search for cache) and monitor your web-server logs.

Since the documentation/demos don't include any iFrame examples I wonder if this is officially being supported at all.

I think,

  • #4534 solves a similar problem, but does not solve this problem.
  • This problem is like #5575.
  • It's a problem, but it's not a bug of the dialog.

There is no workaround in this component.

I think you counted,

  • when dialog _create

1. Appending uiDialogContent to uiDialog.

2. Appending uiDialog to document body.

  • when dialog destroy

3. Appending uiDialogContent to document body.

I think it may be a workaround (outside this component):

1. In the html source, set the src of the iframe to 'about:blank' or 'javascript:false'.

2. Create dialog with {autoOpen:false}.

3. Set the src of iframe.

4. Open the dialog.

5. Before desroying, Set the src to blank.

  • 'about:blank' may have a problem with 'https:'.
  • I have heard someone says 'javascript:' is slower than 'about:blank'.

I made a mistake.

I should have written like this:

1. Appending uiDialogContent to uiDialog when dialog _create.

2. Appending uiDialog to document body when dialog open.

3. Appending uiDialogContent to document body when dialog destroy.

When {autoOpen:true}, 'dialog open' is called from 'dialog _create'.

I still have the same problem, but in my situation the iframe reload 2 times when I open it and 2 times when I close it.

With this solution:

    In the html source, set the src of the iframe to 'about:blank' or 'javascript:false'.
    Create dialog with {autoOpen:false}.
    Set the src of iframe.
    Open the dialog.
    Before desroying, Set the src to blank.

... I get rid of the 2 reloads during the close event, but still the iframe reload two times when I open the dialog, and only if I use an effect on the option "show".

Reproducible in latest Firefox. I tend to close this as wontfix/cantfix and extend the documentation to say that iframes inside dialogs cause trouble.

There's nothing we can do about this. You can track the Firefox bug at https://bugzilla.mozilla.org/show_bug.cgi?id=254144

I'll ping Mozilla about this to see if we can get some traction on the bug, but seeing as how it's been open for 8 years I wouldn't expect too much.
