JsonStore can't load empty list

[zafiro]

Hi:
I want to submit records to be deleted from my database; however, I don't want to reload all records that weren't modified.

I tried by using jsonStore.load({add:true, ....}) and retrieving an empty list for the records to add:

{"success":true, "records":[]}

However it breaks!

Here is the stack trace from Firebug:


r has no properties
(no name)([Object name=nombre id=0 locked=false], [undefined, Object id=1012 data=Object json=Object store=Object], Object data=[6] baseParams=Object paramNames=Object, 6, 1, true)ext-all-debug.js (line 27806)

getViewWidth(Object conn=XMLHttpRequest tId=7, Object scope=Object argument=Object timeout=30000, undefined)ext-base.js (line 12)
getViewWidth()


First question: Is there another way to get this behaviour?
Second: Anyway, this method shouldn't break with an empty list, right?

Jaja, in the meanwhile I am returning a dummy record (id=-2) and erase it as soon as the success callback is executed, along with the other records I had to erase :))

I usually send delete requests to the server like this:



var conn = new Ext.data.Connection();
conn.request({
url:'request.php'
, method:'post'
, params:{cmd:'delete',id:id}
, callback: function() {
// something useful
}
});

Thanks. That looks a lot more natural :)
