View Full Version : [OPEN] [FIXED]selectionchange event is fired twice

18 Feb 2011, 12:54 PM
This looks weird, the event is fired twice, and with different arguments.

Go to this page

Open console and execute this script, then click on grid.

cls = Ext.grid.GridPanel;
Ext.util.Observable.capture(cls.prototype, function() {
}, cls);

Can't confirm this. What browser are you using? Note that the selectionchange event is fired for both selection and deselection.

Hi Evan,

i'm on FF4b and observe in FB 1.7X

Ok, deselect make sense. But if i look to the arguments i can't differ between both.

First event has arguments
"selectionchange", Object event, []

Second has
"selectionchange", Object event, Object record

looking to event object, there is no advice about select or deselect, they are looking identical (maybe i oversee something ?)
In event.events i find 3 events: select, deselect and selectionchanged, but select/deselect seems not to be fired.

I'm not seeing that.

See the attached screen. The first event is fired when I click the first row. The next 2 are fired after I click the second row (deselects the first).

You are right with the count of events (I already confirmed if one is for select, the other for deselect)

But then,
* select/deselect event is missing
* examine both selectionchange events. I think first is the deselect, it's fired without record.
* There is no indicator in event object of both, which kind it is (select/deselect)

In 3.x it makes no distinction as to whether it's a deselect/select as well. If you need a specific event, you should listen to select/deselect.

I've added a fix to ensure select/deselect get fired.
