View Full Version : [CLOSED] data.Store sync() method returning error after 0.91

30 Jun 2010, 3:07 PM

I am using a data.Store with a localStorageProxy like this:

charStore = new Ext.data.Store({
proxy: new Ext.data.LocalStorageProxy({
id: 'charStore-Proxy'
autoload: true,
id: 'characterStorage',
storeId: 'store4char',
model: 'Character',

When I create a new record and add it to the store, then call charStore.sync(), everything is fine:

charStore.add(Ext.ModelMgr.create({name: thisChar.stats.name, character: thisChar}, 'Character'));

However, attempting to add any subsequent records causes this error:

ext-touch-debug-w-comments.js:8037 TypeError: JSON.stringify cannot serialize cyclic structures.

Had never seen this before. Commenting out the sync() function makes everything perform as expected.

We don't immediately see the problem here and aren't able to reproduce it. Could you please provide the Character model definition? Even better would be to give us a copy of your javascript so we can look at it and hopefully reproduce the problem. If you dont want your source code to be public you can send it to tommy@extjs.com.

@tmtrademark if you are still getting this behavior please post a reproducible test case otherwise we'll close the ticket as it appears to work in all of our tests.
