Loading Problem in List Grid with One record in the Datasource.

[chinjurani]

Hi,
When i load data to listgrid using datasource which is having only one record, Data is not loading to grid. Getting the message like Loading data.. But it is not loading. when I am having more than one record in the Datasorce data is loading into grid.


(I have a datasource. Data is added to it using RPC.
After that i am setting that datasorce to my grid.)

Hi chinjurani
i am also facing the same issue,
i dont know where i am doing the mistake. did you get any solution?

I had the same problem. To fix it for datasets that had only one row I added a blank row and it seemed to solve the problem

Guys,

I just changed my code from

 listGrid.setAutoFetchData(true);

to

 listGrid.fetchData();

it is working perfect.I also tested for 1 to 15 rows and result is good.

please post me if you got any issues by using this solution

There shouldn't be a difference between fetching data via autoFetchData() vs an explicit call to fetchData()

If you'd like to post a standalone test case we can use to reproduce the issue we can take a look and see if there's an actual bug here

Happening to me in the latest release version. My ListGrids use setAutoFetchData(true).
If a ListGrid has exactly one record it will not remove the loading data message and icon and draw the one row.

This is my workaround:

		// workaround when one and only one row is fetched.
		addDataArrivedHandler(new DataArrivedHandler() {
			public void onDataArrived(DataArrivedEvent event) {
				markForRedraw();
			}
		});

ohmi - definitely not a general problem. Closely inspect your response when there's one row to discover the actual problem, most likely an off-by-one in your startRow/endRow/totalRows numbers.

Thanks -- I am reviewing, but I do not use any of that kind of capability and never look at the number of rows myself -- it's all rows all the time. So if it's an off-by-one error, it's not in my code.

If you say so :) Let us know if you can produce a standalone, runnable test case demonstrating an issue with single-row results.
