    Default Answered: EXTJS 4.1.1. TabPanel-problem on Firefox: iframes reloads when switching tabs

    I've got a problem with PDF's in the TabPanel (only on Firefox). They are reloading everytime I switch tabs. The PDF is in a iframe.


    Because of it the user can not compare two PDF files. When you click a tab with a PDF it loads 10 seconds, then you switch to a second tab and it also loads 10 seconds and so on....


    I know this problem with Firefox has been around for years (which relates IFRAME, OBJECT, EMBED elements). It cannot be that there is no solution for this problem.

    However, I have not found any for Extjs4 yet.


    It would be great if someone could help me with it.

  2. Thanks. I have solved the issue.

    with following child's config settings:

    PHP Code:
    ...
    style:{position:'absolute'},
    hideMode:'visibility',  
    ...

    Hi,

    I'm not familiar with that issue, so this is a stab in the dark, but you might try setting the tabpanel's child items' hideMode to offsets or visibility and test:
