Thread: [4.2.1] fileuploadfield change listener not fired when browsing cancelled.

    Success! Looks like we've fixed this one. According to our records the fix was applied for EXTJS-8124 in 4.2.2.

    Default [4.2.1] fileuploadfield change listener not fired when browsing cancelled.

    REQUIRED INFORMATION

    edit: this is a regression from 3.x

    Ext version tested:
    • Ext 4.2.1
    Browser versions tested against:
    • Chrome 28.0.1500.95 (Linux)
    • Firefox 23 (not reproduced)
    Description:
    • In chrome, after clicking to open the file browser, clicking cancel will reset the field (to empty) but will not run the change listener or validator function. In firefox, clicking cancel leaves the field as-is so there is no change and the listener is correctly not run.
    Steps to reproduce the problem:
    • In chrome, create a fileuploadfield
    • click the button that opens the file browser and select a file, then open
    • click the button again to open the file browser, but this time click cancel
    The result that was expected:
    • If the textfield is cleared, the change listener should be run
    • If the textfield remains unchanged, the change listener should not be run
    The result that occurs instead:
    • In chrome, the textfield is cleared and the change listener is not run
    Test Case:

    Code (untested, something like the following):

    Ext.create('Ext.form.field.File', { renderTo: Ext.getBody(), listeners: { change: function(){ debugger; } } });
    HELPFUL INFORMATION

    Workaround
    • For now, since there is no listener for this, we validate the form when you attempt to submit it.
    Operating System:
    • Linux
    A related issue is setting the msgTarget to "qtip" does not work using the neptune theme for fileuploadfield. When an error occurs the border should be red, but it is not. We have an easy workaround so I'm not pursuing this further.

    I was definitely able to reproduce this issue, all the way back through 4.0.7 at least, but it is not happening using the latest nightly build of 4.2.2. Hopefully you see the same results.

    Should be fixed for 4.2.2, EXTJSIV-8124.
