Ext-Persist problem

[mafar]

Hello, I am experiencing problems using persist plugin.
I am using table ext along-with persist-ext. But when I reload my page, Tree doesnt recover last selected node. Is there a problem with my Json ?

Note: To explain my issue, I am using JSFIDDLE, so If you select any node and press RUN in jsfiddle, it should recover last active node by selecting it.

1st JSFIDDLE:
This is not working for some reason and doesn't recover my last selected node when i press run button in fiddle.

2nd JSFIDDLE:
This some how works.

I cant figure what`s wrong in my 1st JSFIDDLE: which is my real example.

I couldn't reproduce this (both fiddles don't seem to wirk here).
Please post some code that helps to reproduce this (see /test/triage for templates)

Ok, I i have been looking into this and found the problem.
Persist ext is expecting string as value of key. SO
{"key": "2", "title": "abc" } will work
but {"key": 2 , "title": "abc" } wont because 2 is int not string.

However most of the time DB`s have unique keys and on server-side keys are returned as int instead of strings as they are unique.

According to http://en.wikipedia.org/wiki/JSON
int/Boolean are not stringified as standard practice.

I added this example at /test/triage
