Hi,…ciao :-) Daniele
there is something that set null to _displayGroup after the page render ?
Seems like that when u click on the link the displayGroup() method is called
again and resets the _displayGroup array (is something had set it to null).
Put a braakpoint there and check.

Hi everyone,
my app is doing something of strange, and I don't understand what it's wrong
with my code.
I've some Entities that I've to display in a table, so I use the
ERXDisplayGroup class.
Here an example:
public ERXDisplayGroupCollaborator displayGroup() {
// IF Null instantiate it
if(_displayGroup == null){
_displayGroup = new ERXDisplayGroupCollaborator();
EOArrayDataSource dataSource = new
EOArrayDataSource(EOClassDescription.classDescriptionForEntityName(Collaborator.ENTITY_NAME),
editingContext());
//Check user is logged in
if(session().hasUserLogged()){
//Check if user has chose the company
if(session().hasChoosedCompany()){
dataSource.setArray(Collaborator.fetchCollaboratorsForCompany(editingContext(),
session().company()));
}
}
_displayGroup.setDataSource(dataSource);
_displayGroup.setCurrentBatchIndex(1);
_displayGroup.setNumberOfObjectsPerBatch(NUMBER_OF_OBJECTS_PER_BATCH);
_displayGroup.fetch();
}
return _displayGroup;
}
this method is called as binding in the loop component:
wo:loop list = $displayGroup.displayedObjects item = $object
and the object binding is simply a variable of the component.
private Collaborator object;
//With public getter and setter
on each row I've a link that call:
public WOActionResults selectObj() {
this.parent().takeValueForKey(object, selectedCollaborator);
return performParentAction(selectCollaborator);
}
Ok, I'm able to filter the list using the setQualifier method of the
DisplayGroup:
public void setQualifier(EOQualifier qualifier){
displayGroup().setQualifier(qualifier);
displayGroup().fetch();
}
public EOQualifier qualifier() {
return null;
}
I call the list component passing the qualifier binding in the parent
componet:
wo:CollaboratorsList qualifier = $qualifier/wo:CollaboratorsList
When I pass a qualifier the page show the filtered list correctly.
The problem is: when I click on the link with action = $selectObj of the,
for example, 2nd object of filtered list, the object variable in the class
does not contain the instance related to the selected row, but the instance
in the second position of the full list of objects in the displayGroup.
Example:
a table with:
---
| link | Mario Rossi | The Address 1 | His City |
---
| link | John Smith | The Address 2 | City2 |
---
| link | Francis Cabret | The Address| His City |
---
---
I filter the list for name LIKE *John Smit* and get only one row.
---
| link | John Smith | The Address 2 | City2 |
---
but when I click on the link, in the action selectObj(), the object variable
contains the instance for Mario Rossi.
That's strange for me...
I thought this should have work, but, evidently, is not so!
Which is the correct way to use the ERXDisplayGroup.setQualifier method?
Thanks in advance!
