fnSaveState being called multiple times with ColReorder plugin

mkonecny

Hello, I'm having a problem where I'm using the ColReorder function and my fnSaveState callback is being called twice.

I've used the Chrome debugging tool to view the stack trace, but I haven't gotten very far.

If you look at the stack trace, you see that after line 4851, the code diverges. One on code path is goes to builder.js:420 which is in my fnSaveState callback,
on the other code path, it first goes to ColReorder.js which eventually calls my fnSaveState callback again.

Line 4851 in datatables 1.9.4 is a for loop which iterates over the callback's defined. Any idea why this is happening? I tried the official ColReorder plugin demo, and could not recreate this behaviour there.

I should also note that on line 4851, the value of sState is "aoStateSaveParams"
