Extjs 4 form still has an entry after form.reset ();

Question

I have a grid attached to the form that represents the action of the form, to update the loaded record, if there is one, and add a new record if its form is empty. but if you select the record first and then call

myGrid.getSelectionModel().deselectAll();
myform.getForm().reset(); 

to clear the form so that I can add a new record, it overwrites the previously selected record with the update.

record = myform.getRecord();
if(record){
record.set(values);
}

should not myform.getRecord (); be null after a reset? how to clear record selection?

• ExtJS 4.1.1
• TreePanel

In ExtJS 4.1, in the sync () method, you can use the options object in which you can define callback, success, and failure functions. Since I am sure that I only sync only one record, I downloaded the returned record:

me.getHelpItemsStore().sync({
    success: function(batch) {
        // We expect single operation so...
        var record = batch.operations[0].getRecords()[0];
        form.loadRecord(record);
    }
});

A little late, but hope will help you.
