Hi,
I'm hoping that the following problem sounds familiar to someone and I could
get some help,..
My editors do save (serialized to a bytestream) and restore without any
problems, except for one thing: children of container parts are not
restored at all. The container figure itself is there, but its children are
missing.
It seems that they moved out of the container to the absolute coordinate
they originally had within the container. So if a child figure had the
coordinates (10,10) within a figure it now has (10,10) as absolute
coordinate value. And it only seems to be this way, because connections
pointing to those figures now point to empty areas in the editor.
All objects, that are directly children of the actual editor part/model are
restored correctly.
Is this too little information?
What am I doing wrong? Any hints?
Thanks in advance,
Fabian

Could you send some code to see what's wrong ?

Hi,
if I only knew which pieces of the code.
Does this sound like a layouting problem, like a problem creating the
EditParts, like a problem with the actual container figure? Its scrollpane?
Something else? You see,... without knowing where these problems arise,
it's hard to fix them. Any idea?
The entire editor has now a little more than 10k lines of code - slightly
too big to post it here :(
Maybe a picture can explain the problem better than I can:

Thank you very much though for being interested!

Suggestions :
Do you have a ContentOutline ? If yes, are the children still present
"After" * ?
=> If yes, they've been created successfully but it's just a problem of
positionning, so I would have a look at the setLocation() method of your
child model class, or at any method in the corresponding editpart that
cares about layout and painting : refreshVisuals, layout edit policy, ...
=> if no, I would have a look at everything serializes/deserializes the
component and also have a look at getModelChildren in the container
editpart (but you should have other bugs if it is involved)
Finally, you could go in debug and follow the creation of your model
step by step to see where is the problem.
Another idea : you seem to have a custom contentpane in "system agent"
figure, maybe have a look in this way.
Hope this helps,

* if you don't have a ContentOutline implemented, just put some
"System.out.println("Child created " + child.getName())" in the
Constructor of your children model class to check if the children are
serialized or not.

Hi Arnaud,
I thank you so much - I feel pretty stupid. The problem was, that I was
implementing getModelChildren() without actually filling it with code,...
only the super()-call which returns an empty List.
Thanks a lot,
Fabian
