Hi All;

I have created a .uml file using UML2 APIs in Eclipse 3.4 as directed by
the article "Getting Started with UML2".

http://www.eclipse.org/modeling/mdt/uml2/docs/articles/Getti ng_Started_with_UML2/article.html

When I perform the actions on same .uml file using UML2 Tools:
-initialize Class Diagram
-initialize Use case

it generate the diagrams very well.

But on generating "initialize Activity Diagram", it generates the jumbled
diagram which can not be arranged even after selecting 'Arrange All'
action on it.

Please tell me, How can I fixed this problem??
Or There is a bug in UML2 tools??

Your view will be highly appreciable.

Thanks In Advance.

Regards,
Kishore

Hi,

The reason of such behaviour is that GMF layout operates with only top level
nodes. In case of Activity diagram there is solely one top level element
(Activity) usually. I can suggest only one way to fix the problem, to select
nodes inside Activity and invoke "Arrange selection". However this solution
is not ideal, because "Arrange Selection" assumes that selected nodes are
top level ones and can place node out of Activity. So place Activity to top
left corner and resize one as large as possibe to avoid placement nodes out
of bounds.

Thanks Sergey for suggestion.

But As you told about "Arrange Selection" after selecting a child node is
also unable to make the Activity Diagram proper. It is not helpful when,
there are large number of child nodes & edges inside Activity Node. No one
can select the proper node & its edges for arranging it manually.

BTW, I am asking about any built-in methods from APIs to arrange Activity
Diagram properly after just its creation; B'coz I am generating such
digrams by a program.

Please tell me, How can I fix this bug.

Thanks in advance.
Kishore

Hi all,

I have the same problem with activity diagram generation.
and I am asking about any built-in methods from APIs to arrange Activity Diagram properly after just its creation.

Thanks in advance,
