The actions creates a new company with the users company as the parent
(reseller). There's a nested set JDO implementation for managing a company
tree. The nested set is updated by the mentioned parent.addChild(childNode).
I'm new to JDO. Try to execute a bulk update by modifying selected entities
during an transaction.
List<CompanyNode> rightNodes = (List<CompanyNode>)qLeft.executeList();
// actual update
nsm.getPersistenceManager().currentTransaction().begin();
for (CompanyNode node : rightNodes) {
int newRight = node.getRightValue()+delta;
node.setRightValue(newRight);
}
nsm.getPersistenceManager().currentTransaction().commit();
// action
public AbstractCompany create(
final @Named("Bedrijfsnaam") String name,
final @Named("Is reseller") @Optional Boolean isReseller) {
AbstractCompany obj;
Company usersCompany =
findCompanyRepresentedByUser(getUser().getName());
if(isReseller != null && isReseller){
obj = newTransientInstance(Company.class);
obj.setName(name);
obj.setReseller(true);
} else {
obj = newTransientInstance(EndUser.class);
((EndUser)obj).setReseller(usersCompany);
obj.setReseller(false);
obj.setName(name);
}
// create nestedSetElement for the new company
CompanyNode childNode = newTransientInstance(CompanyNode.class);
childNode.setName(obj.getName());
childNode.setCompany(obj);
Node<CompanyNode> parent =
getNestedSetManager().getNode(usersCompany.getCompanyNode());
parent.addChild(childNode);
// Necessary?
obj.setCompanyNode(childNode);
persistIfNotAlready(obj);
persistIfNotAlready(parent);
return obj;
}

Doesn't look right, that's for sure.
Can you provide some more detail - what's in the action's implementation?
Thx
