Hi

When I click at a slice of pie chart it moves and I get the value based on current row. It is ok, but if I do a click at the same slice, I receive an error: Datasource xxxx has no current row.

What can I do about this error? I am using the following sintax:

situation := api_datasource.getColumnValueTX('ds_pie_all_tickets.situation');

Thanks, Ricardo

Hi Ricardo,

When you click a slice, it becomes the current row of the chart datasource. When you click the same slice again, the current row of the datasource is set to null since there is no more a selected slice in the pie chart. You can use api_datasource.getCurrentRowID API to check whether there is a current row in your datasource(selected slice in your chart).

if api_datasource.getcurrentrowid('ds_pie_all_tickets') is not null then
  situation := api_datasource.getColumnValueTX('ds_pie_all_tickets.situation');
end if;

Hope this helps,
Ibrahim
