blank space at the bottom of listgrid

[bakosa]

Hi,

We are using v8.2p_2012-06-25/Pro, and we see the following problem in all major browsers (IE9, FF14, Chrome20):
We have a listgrid with large data, and we show it all, no paging is used. We added a new widget to one of the cells. If we scroll down to the bottom of the listgrid, we see a lot of blank space. We checked the generated HTML, and those are not blank rows. It's like the scrollbar scrolls the listgrid body a bit more upwards than it should. Without the widget everything goes back to normal.

This is the part responsible for addig the widget:

      recordComponentPoolingMode: 'recycle',
      showRecordComponentsByCell: true,
      recordComponentPosition: 'within',
      poolComponentsPerColumn: true,
      showRecordComponents: true,
      createRecordComponent: function(record, colNum) {
        var dform = null;
        var ref = this;
        var fieldName = this.getFieldName(colNum);
        if (fieldName == 'akcio') {
          dform = isc.DynamicForm.create({
            autoDraw: false,
            fields: [
              {
                shouldSaveValue: false,
                type: "select",
                showTitle: false, 
                optionDataSource: "feladatOsszefoglalo_lista_akcio_DS",
                width: 40,
                pickListWidth: 155,                
                valueField: "a_uid",
                displayField: "a_name",
                autoFetchData: false,
                defaultValue: -1,
                getPickListFilterCriteria : function () {
                  return {event_id:this.form.record.event_id,timecode:isc.timeStamp()}
                },
                valueMap: {
                  '-1': "---"
                },
                changed: function(form, item, value) {
                  if (value!=-1) {
        						akcio_inditas(value, this.form.record.event_id, ref);
                    item.setValue(-1);
                  }
                }
              }
            ]
          });
          dform.viewGrid = this;
          dform.record = record;
        }
        return dform;
      },
      updateRecordComponent: function(record, colNum, component, recordChanged) {
        var fieldName = this.getFieldName(colNum);
        if (fieldName == 'akcio') {
          component.record = record;
          return component;
        }
        return null;
      }
