5.1.0.70 chained store has no isMoving method

This was implemented a while back: EXTJS-14794 ChainedStore should support insert

This is reflected by the fact that ChainedStore implement mixin LocalStore, which has this method:

Code:

 /**
     * Inserts Model instances into the Store at the given index and fires the {@link #event-add} event.
     * See also {@link #method-add}.
     *
     * @param {Number} index The start index at which to insert the passed Records.
     * @param {Ext.data.Model/Ext.data.Model[]/Object/Object[]} records An `Ext.data.Model` instance, the
     * data needed to populate an instance or an array of either of these.
     * 
     * @return {Ext.data.Model[]} records The added records
     */
    insert: function(index, records) {

When a model is inserted to ChainedStore, the store for the model is the chained store.

But then, a lot of methods are expected to exist in the store that own the model. So the chained store class need some methods usually called on a normal store. isMoving method exist in a normal store but not on a chained store.

ChainedStore class method:

Code:

  onCollectionRemove: function(collection, info) {
        var me = this,
            records = info.items,
            lastChunk = !info.next;
        
        if (me.ignoreCollectionRemove) {
            return;
        }
        
        me.fireEvent('remove', me, records, info.at, false);
        // If there is a next property, that means there is another range that needs
        // to be removed after this. Wait until everything is gone before firign datachanged
        // since it should be a bulk operation
        if (lastChunk) {
            me.fireEvent('datachanged', me);
        }
    }

Model class method:

Code:

onStoreRemove: function(store, records, index, isMove) {
        var me = this,
            toDeselect = records,
            moving, i, len, rec, moveMap;


        // If the selection start point is among records being removed, we no longer have a selection start point.
        if (me.selectionStart && Ext.Array.contains(records, me.selectionStart)) {
            me.selectionStart = null;
        }


        if (isMove || me.locked || !me.pruneRemoved) {
            return;
        }


        // Do a cheap check to see if the store is doing any moves before we branch into here
        moveMap = store.isMoving(null, true);
