Re: [SCXML] Javascript as expression language
Hi Ingmar, I'm not in a hurry but wanted to know if this was still likely to happen. Thanks for the reply!

Re: [SCXML] Javascript as expression language
Hi Roger, you are right - this is still an open issue. Sorry for the "delay". Beginning from May (this year ;-) I will have a (part time) intern and I will put him on this issue first. So there is good hope. If you can wait for another few days?

You will find that as more and more of the application-specific
patterns (and requirements) emerge, it is convenient to encapsulate
these patterns as custom actions (perhaps a time to rethink the no
custom action constraint).
Without that, you could always store the name (lets call it 'delta',
which signifies that it identifies the change) in the root context,
update it with every assign as needed and look it up for your
notifications, so along these lines (continuing example from earlier
in this thread):
...
...
and the Context#set() method previously discussed would then change
along these lines:
public void set(String name, Object value) {
// inherit behavior
super.set(name, value);
// notifications you need
// the second param is the new info needed
notify(name, get("delta"), value);
}
Now, OTOH, all of this can really be distilled into a compact custom
action such as:
whose implementation encapsulates the pattern of updates and
notifications as needed by the application and thereby leaves the
markup cleaner.

Re: [SCXML] getting set datats in the datamodel
Hi, Is there anyone who has any idea what to do about this? Even a little hint would be appreciated, you don't have to solve the whole problem! /Linda <-Ursprungligt Meddelande-> From: Linda Erlenhov [u...@commons.apache.org] Sent: 23/4/2009 2:30:58 PM To: Commons Users List Subject: Re: [SCXML] getting set datats in the datamodel Hello again! This seems to work, since we now can see that data has changed. Unfortunately, we seem to have missed out an important part of the question. In addition to being notified when a data value is set, we also would like to be able to "get/recieve" the new data value aswell as the name (in this case numdat) so that we can display it to the screen in our interface. And, in this example we only have one data value, NumDat. However, it is possible to define several data values insade the DynamicData-tag. Can we still just write after the first assign tag, or do we also have to define what data value has been changed? Sincerely, Linda > > > Yup, I see what you are running into.
