FRM-41072:Can't create Group (for a tree)

Question

Hello,
the following code is trying to refresh data while saving the record which is a child of the child of the Grand parent.
In Key-commit Trigger..
The Query was working just fine without the new modification concept to have a child from the child.
e.g.
Electrical Equipment
|_ Computer
       |_ Mother BoardAny way the Query works fine in Toad it displays what i want but in the forms' tree ..!!!
Getting the following Error:
--===========================
FRM-41072:Can't create Group RG_DAL_MED
FRM-41076 :Error populating Group.
FRM-41085 :Error getting Group Row count.
--===========================
Using Forms 6i Windows XP ..!

     selektas := 'SELECT 1 NODE_STATE,                    LEVEL NODE_DEPTH,
                                   EQUIPMENT NODE_LABEL,
NULL NODE_ICON,
     EQUIPMENT_ID NODE_VALUE           FROM INSP_EQUIPMENT
          WHERE V_WHERE ';You have to add the V_WHERE as a value to your select:
selektas :=  'SELECT  1       NODE_STATE,
                      LEVEL               NODE_DEPTH,
                      EQUIPMENT            NODE_LABEL,
                      NULL                 NODE_ICON,
                      EQUIPMENT_ID         NODE_VALUE                          
                 FROM INSP_EQUIPMENT
                WHERE ' || V_WHERE;
