LazyDataModel.findRows called recursievly from unrelated search field

[Abey M, geändert vor 7 Jahren.]

Hi,
I am using the Lazy data model for populating the ui table.
I noticed that when changing the value in start date in search criteria, the findRows method is recursively called, causing multiple calls to the backend before the values are set. This is causing heavy backend traffic and bugs.
How can I make icefaces to call findRows only on clicking the Search button?
Thank you.

The DTO class is

public class MyTO implements com.liferay.faces.util.model.LazyDataModel
...
@Override
	public List<myto> findRows(int startRow, int finishRow) {
		return service.geRecords(this, startRow,
				(finishRow - startRow) + 1);
		//return null;
	}
...
}</myto>

Hi Abey,
Can you try ace:dataTable with IceFaces LazyDataModel instead?

There's an example of how to use ace:dataTable with a LazyDataModel implementation in our old icefaces-users-portlet.
