Remove element from collection

[Anton Pirker]

Hi List!

I have a collection events in the HopObject User. Now i want to remove
one event from the users list of events by doing: (but it should stay in
the database and other collections of the application)

        session.user.events.remove(eventObj);


this happens in the action. after this i render a skin where a macro is
called where i check for existence of the removed event

        if(session.user.events.get(eventId)) { do something }

the problem: the collection is not updated (the event is not removed) to
the if-statement is always true. only when i restart helma the event is
gone.

how can i remove an element from a collection so that it is removed
immediately so that i can check for its (non)existence in the same
request and get the right result.


cheers,
Anton

Hi Anton,

I think, res.commit() is what you're looking for.

This does not do the trick..

It seems that .removeChild(childObj) has no effect at all when the
childObj ist still in the database.

Has anybody else an idea?
Any help greatly appreciated!

Greetings from sunny Vienna,

I found the error.

i had a wrong .accessName in the definition of my collection so .get()
returned something when it should not.

sorry for the noise,
Anton
