Found a few bugs when loading via server side ajax

Have been having issues trying to get StateRestore to load all states via server side Ajax call

using the function style ajax calls per See Here to control all the server side saving

I have never seen if (data.action === 'load') option ever fire... so I resorted to using the ajax stateRestore option on initial load
as See Here

Everything works until browser refresh and then you can't update any of the existing based on this area in StateRestore.ts (line 751-758)

//If the state is predefined there is no need to save it over ajax or to local storage
if (this.s.isPreDefined) {
	if (passedSuccessCallback) {
		passedSuccessCallback.call(this);
	}
	return;
}

what occurs is all the states are set to isPreDefined: true even for ajax loading

There is also a typo in StateRestoreCollection.ts where you in line 641-647

currState.stateRestore = {
isPredefined: false,
state: id,
tableId: this.s.dt.table().node().id
};

It s/b isPreDefined not isPredefined

I looked at your source code and I don't ever see a callback for the load process, and all the function Ajax examples don't ever load server side.

Your above initialisation/ajax.html example fails the same way

Steps:
1: Load a new state and try all the options (Rename, Update, Remove) they all fire a callback to server
2: Keep at least one state and re-fresh browser.
3: You can do all options except Update (check and all the loaded states are now IsPreDefined)

In my case, I never have preDefined: in the DataTable settings... so I turned off the true condition in StateResotrCollection.ts
_addPreDefined (line 878)

So in closing,
A) is there a way to load via function call Ajax from the server or
B) you should change the _addPreDefined call to add a boolean to set that isPreDefined to false for Ajax loads

Thanks

Start with StateRestore.ts lines 751-758 and StateRestoreCollection.ts lines 641-647 and 878. Reproduce the refresh scenario using the linked ajax examples, checking whether loaded states can be updated and whether the function-style load callback fires. Done means server-loaded states retain the correct predefined status and the documented update behavior works after refresh.
