dojox.data.JsonRestStore should have a public method to clear its cache

[Ed Chatelain]

When trying to reload a tree using a dojox.data.JsonRestStore?, the only way I have found to clear the cache in the JsonRestStore? requires the use a a private variable _index.

In this ticket ​http://bugs.dojotoolkit.org/ticket/11065 there is code that clears the cache as part of a reload function. The code below works, but a public method is needed to do this without having to use the private _index.

storeTarget = this.model.store.target; for (var idx in dojox.rpc.Rest._index) {

if (idx.match("^{" + storeTarget)) {}

delete dojox.rpc.Rest._index[idx];

}

}

I will attach a zip with a test to show the problem, and a patch to add a clearCache function to JsonRestStore?.

Attached is a testcase with an html file and 2 .json files. To see the problem hit index.html and click the refresh button. The refreshed tree will have a duplicate zzz node. If the code in tree_refresh above is uncommented (or the clearCache fuction is added and called) the duplicate node problem will not occur.

Patch from Ed (IBM, CCLA).
