[OPEN] [#901] [3.2.1] Multiple selection treefield closes automatically at each selection with 3.2.1.

[adrianot]

Hi, we've discovered that the latest version of Ext.Net (3.2.1) behaves incorrectly on tree editors with multiple selection.

It appears that selecting any option on the tree drop down closes the drop down at each selection.

Look at this sample to reproduce the issue:

This is a blocking issue for us, could you pls fix this?
Thank you!

PS: With 3.1.0 it worked fine

Hi @adrianot,

Thank you for the report!

Created an Issue.
https://github.com/extnet/Ext.NET/issues/901

The issue appears to be not reproducible in IE and Firefox. I guess you are testing with Chrome.

Somehow, this code in TableView's handleUpdate makes the body focused in WebKit (Chrome, Safari, Opera).
cell.childNodes[0].innerHTML = value;


So, a DropDownField blurs and collapses.

This override appears to help getting rid of the issue. Please try.

if (Ext.isWebKit) {
    Ext.tree.View.override({
        afterRender: function () {
            this.callParent();
            this.el.on({
                mousedown: {
                    delegate: this.checkboxSelector,
                    fn: function (e) {
                        e.preventDefault();
                    },
                    scope: this
                }
            });
        }
    });
}
