I have a listgrid which isn't scrolling smoothly. When scrolling down, the records "jump" to different position. It is difficult to explain but after testing a lot I have a testcase:
The "table" datasource is nothing special:
When scrolling down, as I said, the records jump to an upper position, so the scrolling is not smooth.
If I remove this:
lg.setCanExpandRecords(true);
then the scrolling is smooth again.
So I guess there is a bug with record expansion.
Using smartGWT 4.1p: SmartClient Version: v9.1p_2014-10-28/PowerEdition Deployment (built 2014-10-28).
Code:
public class TestingModule implements EntryPoint {
@Override
public void onModuleLoad() {
ListGrid lg = new ListGrid();
lg.setDataSource(DataSource.get("table"));
lg.setCanExpandRecords(true);
ListGridField idField = new ListGridField("f_name");
idField.setTitle("name");
lg.setFields(idField);
lg.setWidth100();
lg.setHeight100();
final VStack layout = new VStack(10);
layout.setWidth100();
layout.setHeight100();
layout.setMembers(lg);
lg.fetchData();
layout.draw();
}
}Code:
<DataSource ID="table" serverType="sql" tableName="t_schueler"
>
<fields>
<field name="f_schueler_id" type="sequence" primaryKey="true" />
<field name="f_name" type="text" />
</fields>
</DataSource>If I remove this:
lg.setCanExpandRecords(true);
then the scrolling is smooth again.
So I guess there is a bug with record expansion.
