View Full Version : [NOREPRO] Stop Store Event Bug

11 Apr 2012, 12:28 PM
I have a store that I've been using for two different views. Sometimes when I go from one view to the other, I want to reset the store. I can remove the items but pending AJAX calls then load items intended for view 1 while I am looking at view 2. Here's what I've been using and it's been very inconsistent.

var store = Ext.data.StoreManager.lookup('Items');
store.removeAll(true) // clear the store
store.suspendEvents(); // shouldn't this stop all pending events, wiping them out?
store.resumeEvents(); // I want to then resume looking at events but sometimes it resumes the old events too. I know that it shouldn't based on the API docs

Thanks for your help

The name of the method is suspendEvents... is suspends the events.

Right, I hear you but in the API docs, it says:

suspendEvents (http://docs.sencha.com/touch/2-0/#!/api/Ext.mixin.Observable-method-suspendEvents)( Boolean (http://docs.sencha.com/touch/2-0/#!/api/Boolean) queueSuspended )Suspends the firing of all events. (see resumeEvents (http://docs.sencha.com/touch/2-0/#!/api/Ext.mixin.Observable-method-resumeEvents))

queueSuspended : Boolean (http://docs.sencha.com/touch/2-0/#!/api/Boolean)Pass as true to queue up suspended events to be fired after the resumeEvents (http://docs.sencha.com/touch/2-0/#!/api/Ext.mixin.Observable-method-resumeEvents) call instead of discarding all suspended events.

It leads me to believe that if I do suspendEvents(false), then the events get discarded. My events are NOT getting discarded.

If that is not the intent, how do I "destroy" the store? I want to reuse the store but don't want any of the old data or events. Thanks.

Seems like we need to clarify this quite a bit.

Okay good to know. Any suggestions on any alternatives in the meantime?

This looks more like an async issue. Do you know if there are outstanding calls pending when you suspend the events?

So here's what's happening.

I open a search panel and load a keyword search into the store. The search somes takes 3-4 seconds to complete. If I leave the search panel and destroy it, then do another search using the same store, I will end up getting the results of the first store and then those get cleared when I get the results of the second store. I need to stop the stores refresh event based on th store count I show/hide other panels.

Is it possible to instantiate different instances of the same store each time I load the panel? I've never really seen that in action...

You could do a new store per panel, but first I'd try to abort any pending requests. Can you try to slip in a Ext.Ajax.abortAll() before your resumeEvents? You really only want to about the one specific request, but thats a bit more work to get to and this should at least tell us if aborting the pending request fixes the problem.

Hi Jamie,

The Ext.Ajax.abortAll() worked great. This works better for my needs. This makes it so that the first request is always ended before I start the second request.

Interesting note about Ext.Ajax.abortAll() that I didn't expect is that the 'refresh' event and all events still fire, they just fire immediately after the abort call.
