Ext version tested:
 Browser versions tested against: Description:
 Make a combo box allowBlank: false. You can select a value and then delete it. Didn't used to work that way in older Ext versions.

Steps to reproduce the problem:
 Created a fiddle here:

To see the problem:



  1. Select a value from the drop down.

  2. Select the value.

  3. Delete the value.

  4. Now tab off.


Rather than selecting the value that was chosen, the combo is empty.

I suspect the problem is here:



Code:



    assertValue: function() {        var me = this,
            value = me.getRawValue(),
            rec, currentValue,
            displayValue = me.getDisplayValue();


        if (me.forceSelection) {
            if (me.multiSelect) {
                // For multiselect, check that the current displayed value matches the current
                // selection, if it does not then revert to the most recent selection.
                if (value !== displayValue) {
                    me.setRawValue(displayValue);
                }
            } else {
                // For single-select, match the displayed value to a record and select it,
                // if it does not match a record then revert to the most recent selection.
                rec = me.findRecordByDisplay(value);
                if (rec) {
                    currentValue = me.value;
                    // Prevent an issue where we have duplicate display values with
                    // different underlying values.
                    if (!me.findRecordByValue(currentValue)) {
                        me.select(rec, true);
                    }
                } else if (me.lastSelection) {
                    me.setRawValue(displayValue);
                }
            }
        }
        me.collapse();

    },

Specifically here


Code:



                else if (me.lastSelection) {
                    me.setRawValue(displayValue);
                }

Shouldn't we be doing a me.setValue(me.lastSelection) here?
