Dublicating ListGrid's loadingDataMessage after freezing of a column

[SDorogin]

Hello.

I've encounter an issue with ListGrid (I'm using version 7.0rc2).

I've freezed a column and after that during reloading I can see two messages "loading data".
You can see that at the screenshot: http://cid-966fa37146602c77.office.live.com/self.aspx/.Public/Pictures/sm^_listgrid^_loadmsg.png

It doesn't depend on a browser used (tried Chrome && FF).

Here's ListGrid's code:

var list = isc.ListGrid.create({
	// View:
	alternateRecordStyles: true,
	leaveScrollbarGap: false,
	emptyMessage: "No data",
	loadingDataMessage : "Loading data...",
	// Behavior:
	selectionType: "single",
	generateDoubleClickOnEnter: true,
	contextMenu: listContextMenu,
	// Data:
	dataPageSize: 50,
	autoFetchData: true,
	dataSource: "datasource"
});

UPDATE:
I've also tried SNAPSHOT-2010-07-20 version. There's the same behavior (two messages).

So, what about that issue? Is it know bug, will it be fixed, are there workarounds ?

I reload the shown ListGrid with this code:

		var criteria = filter.getValues();
		list.fetchData(criteria);
		list.invalidateCache();

where filter is some DynamicForm for filtering.

Just a note: you do not need additional invalidateCache() after fetchData() - that will cause additional request to the server.

2marpetr: Yeah. I'm expirience that and can't understand the right use-case.

There're written in docs: "In some cases fetchData() will not need to contact the server as the new criteria can be satisfied by performing a client-side filter against the currently cached set of data. You can determine whether criteria will cause a fetch by calling ResultSet.willFetchData(). "

But I need to refresh data in ListGrid each time. So I write this code:

		var criteria = filter.getValues();
		if (list.willFetchData(criteria)) {
			list.fetchData(criteria);
		} else {	
			list.setCriteria(criteria);
			list.invalidateCache();
		}

But willFetchData always returns 'true'. Even if following fetchData won't fetch server. Tried on today's build.
But it seems to me I've found a solution:

	list.setCriteria(criteria);
	list.invalidateCache();

Thanks, anyway.

So what about the issue (dublicating loading message)?
You can see it even in online sample http://www.smartclient.com/#largeValueMapSQL
Freeze any column then sort to make grid to reload.
