public void selectionChanged(FormTreeItem _oldItem, FormTreeItem _newItem, FormTreeSelect _how)

{

container recIds;

super(_oldItem, _newItem, _how);

psaSummaryActivity.parmPSATmpSchedProjActivity(psaTmpSchedProjActivity);

recIds = psaSummaryActivity.selectionChange(_newItem, psaProjTree.getSelection());

canAssign = conPeek(recIds,4);

qbr.value(queryValue(conPeek(recIds, 1)));

qbr1.value(queryValue(conPeek(recIds, 2)));

isSummary = conPeek(recIds,3);

psaTmpSchedProjActivity_ds.executeQuery();

//m_oResourceScheduling_Load.initTmpReservation(PSATmpSchedProjActivity.StartDate, PSATmpSchedProjActivity.EndDate);

m_oResourceScheduling_Load.updateTables(psaTmpSchedProjActivity, true);

resourceButtons.enabled(false);

assignmentButtonGroup.enabled(false);

}

Thanks in advance everyone for your help

the error can occur when you are trying to access the queryBuildRange members(methods) without initializing it.

where the above ranges are initialized?
