Setting bind variable value programmatically for master and child VO's

Question

Defined following BC:
Serv VO - Master VO, has Bind_cNum (bind variable)
ServDetail VO - Child VO, has Bind_cNum2 (bind variable)
ServViewLink VL - View link between Serv VO & ServDetail VO
in AMModule Impl have custom WS:
public List<ViewRowImpl> getMyServices(String cNum)
List<ViewRowImpl> result = new ArrayList<ViewRowImpl>();
ViewObjectImpl vo1 = getServ(); //Master VO
vo1.setNamedWhereClauseParam("Bind_cNum", cNum);
vo1.setForwardOnly(true);
ViewObjectImpl vo2 = getServDetail(); //Child VO
vo2.setNamedWhereClauseParam("Bind_cNum2", cNum);
vo1.executeQuery();
while (vo1.hasNext()) {
result.add((ViewRowImpl)vo1.next());
return result;
I am passing same cNum parameter to both Serv VO (Master VO) and ServDetail VO (child VO) as above. (this is in addition to view link bind variable :Id)
It shows in the logs that it is setting the values correctly:
<ViewRowSetImpl> <setNamedWhereClauseParam> [382] Serv ViewRowSetImpl.setNamedWhereClauseParam(Bind_cNum, 11771370)
<ViewRowSetImpl> <setNamedWhereClauseParam> [383] ServDetail ViewRowSetImpl.setNamedWhereClauseParam(Bind_cNum2, 11771370)
<ViewRowSetImpl> <doSetWhereClauseParam> [383] Serv ViewRowSetImpl.doSetWhereClause(-1, Bind_cNum, 11771370)
<ViewRowSetImpl> <execute> [385] Serv ViewRowSetImpl.execute caused params to be "un"changed
<OracleSQLBuilderImpl> <bindParamValue> [394] Binding param "Bind_cNum": 11771370
<ADFLogger> <addContextData> Execute query
-- when executing view link
<ViewRowSetImpl> <setParamValues> [425] ServViewLink_0 ViewRowSetImpl.setParamValues params changed
<ViewRowSetImpl> <doSetWhereClauseParam> [426] ServViewLink_0 ViewRowSetImpl.doSetWhereClause(-1, Bind_cNum2, null)
<ViewObjectImpl> <bindParametersForCollection> [436] For RowSet : ServViewLink_0
<OracleSQLBuilderImpl> <bindParamValue> [437] Binding null of type 12 for "Bind_cNum2"
<OracleSQLBuilderImpl> <bindParamValue> [438] Binding param "Bind_Id": 5018
from above log, when ServViewLink_0 is executed, it is changing Bind_cNum2 bind variable to null.
how can i pass same bind variable value to both Master and Child view objects from AM Impl.java

Answer 1

Try executing the vo1 query before setting the bind variable for vo2, then execute the vo2 query (if that's what you want to do).
