Query Bind Variables problem

Question

I have a ViewObject with bindvariable GroupnameItemname.
In JHeadstart AppDef this item is not bound to model, but included in Quick Search and Advanced Serach, as in "7.2.5. Using Query Bind Variables in Quick or Advanced Search"
First I get an error saying GroupnameItemname*Var* is not found on ViewObject, so I changed the bindvariables to GroupnameItemnameVar
Is something changed here? We are using JHeadstart 10.1.3.3.75 / JDeveloper 10.1.3.4.0
After changing the bindvariablename I have another problem:
I get an error in JhsApplicationModuleImpl.advancedSearch on these lines:
boolean isBindParam = !viewCriterium.isAttributeBased();
AttributeDef ad = isBindParam ? null : vo.findAttributeDef(attribute);
The first line returns false for my bindvariable, so the second line raises an error like "JBO-25058: Definition <attr> of type Attribute not found in <VO>".
In QueryCondition:
public boolean isAttributeBased()
return def!=null; //but def is not null here, it is an instance of DCVariableImpl
This used to work in previous versions of JHeadstart...
Please help,
Greetings HJH

Answer 1

In my MyApplicationModuleImpl (which extends JhsApplicationModuleImpl) I did override advancedSearch.
Copied the code from JhsApplicationModuleImpl and changed a few lines:
After
sLog.debug("executing advancedSearch for " + viewObjectUsage);
ViewObject vo = getViewObject(viewObjectUsage);
I added:
//clear bindParams:
String[] attrNames =
vo.getNamedWhereClauseParams().getAttributeNames();
for (int i = 0; i < attrNames.length; i++) {
vo.setNamedWhereClauseParam(attrNames\[i\], null);
sLog.debug("bindParam leeggemaakt: " + attrNames\[i\]);
And a bit later in the method I made a changed as follows:
// boolean isBindParam = !viewCriterium.isAttributeBased();
boolean isBindParam = viewCriterium.getName().endsWith("Var");
A bit crude, but worked for me...
Cheerio,
HJH
