View Full Version : Ext 4.1.1 Problem with load mask

23 Jul 2012, 7:12 AM
After updating to 4.1.1 and making no other changes I have the loading mask that will not clear .

This not a custom mask just the light grey semi opaque loading mask.

But after the load completes ( i can see the form data in fields) the loading mask stays . Nothing is click able and it effects all the forms that load data ( which are all stand alone js files).

Anyone else seen this ? How can test and reset the mask state ?

As a side note is the Ext lastRegisteredVersion accurate ?

Disabling the waitMsg parameter in the load form handler seem to make the problem go away ... but that mean no loading message and no loading msak.

Please make sure it is a small test case we can use to duplicate your problem.

There was a LoadMask bug which I thought was fixed as of ExtJs v4.1.0; regardless, see if this override has any effect on the problem:

Ext.override(Ext.LoadMask, {
onHide: function() { this.callParent(); }

ChaosTimmy ..Thanks for the feedback .
My load handler is copy from the examples

url: 'myUrl',
waitMsg: 'Loading...'

Under 4.1.0 I would get the loading message dialog while the remainder of the screen was masked. Once the load was complete the dialog and the make disappeared.

Under 4.1.1 the "loading dialog " disappears but the mask remains.

if I disable the wait message ( comment out using // ) the data loads as expected.

Scott this is about as small as i can make it :)

friend - I will investigate that override and get back to you .

So What should i look for in Firebug to check the state of the mask ?
What event triggers a.) the "loading disappearing and b.) the mask removal ?

thanks for the help

Have you had any success in getting a solution for this issue?

We have had the exact same problem. After upgrading to 4.1.1, the mask remains after the loading dialog disappears.

Thank you for pointing me to this thread, this override has solved the issue.
