根据主表ID去筛子表信息

var rsm = new Ext.grid.CheckboxSelectionModel({
    singleSelect : false,
    listeners : {
      rowselect : function(sm, row, rec) {
        var con=[{field: 'bdCrmMaterial',
relation: '=',
value: rec.get('trma_Id'),
javaClass: 'net.uni.util.Condition',
type: 'and'}];
dataInfoGrid.updateCondition(con);
      }
    }
  });
