Loop Node and Conditional Node [message #476278]

Hi,
I would like to ask questions about loop and conditional nodes in activity.

1. It seems that there is no special test/body sections in conditional
node. If I try to create a test section, I can only add edges and
actions in the conditional node and set them as the test section in
clause. The same thing happens to loop node.

2. In loop node there is a loop variable, but if I try to save the
model, an exception about this loop variable occurs: it has no owner.
But everything I have added to the loop node should have gotten its
parent as owner automatically. How to solve this problem?

Does anybody know these?

The conditional node consists of clauses which in turn consist of tests
(ExecutableNode) and bodies (ExecutableNode).
Loop node has tests and bodyParts.
You should be able to add any subtype of executable node to the tests. It
seems to work in the editor.
Are you first creating clauses' with tests?

Can you provide a JUnit test or exact scenario that fails? I'm not sure I
see the issue.

Can you provide a stack trace for the error?

Hi,
Thanks for your answer.

I just want to find out the test/body sections in .uml file, like:

<clause>
...
<body xmi:type="UML:ReadVariableAction"
xmi:id="condbody_ReadVariableAction2">
<result xmi:idref="loopbody_output"/>
<variable xmi:idref="loop_element"/>
</body>
<test xmi:type="UML:ReadVariableAction"
xmi:id="condtest_ReadVariableAction_count">
<variable xmi:idref="loop_count"/>
<result xmi:idref="condtest_OutputPin_count"/>
<outgoing xmi:idref="condtest_cf2"/>
</test>
...
</clause>

It seems that there is another format in it, like:

<clause xmi:id="_Dxwa4HhMEdy5av3IsZJsmg" test="_U279sHhNEdy5av3IsZJsmg"
body="_CS3lkHhNEdy5av3IsZJsmg _SGqOcHhNEdy5av3IsZJsmg"/>

There is no difference between two formats. But I still need to know
whether it is possible or not, the first format to create.

By the way, how to create xmi:id with the name of Node, like
xmi:id="ReadSelfAction" ?

The stack trace:

visibility: <unset>) (isLeaf: false) (ordering: FIFO, isControlType:

Hi Zengyu,

Those features that are not directly owned but defined somewhere in the
model and referenced will be serialized like this ...
<node xmi:type="uml:LoopNode" xmi:id="_RtcBQHsuEdyZsKXxkoCTuw"
name="LoopNode" bodyPart="_6IAyoHsuEdyZsKXxkoCTuw"
test="_6IAyoHsuEdyZsKXxkoCTuw"/>

The actual item being referred to would be serialized like this ..

<node xmi:type="uml:ReadVariableAction" xmi:id="_6IAyoHsuEdyZsKXxkoCTuw"
name="ReadVariableAction"/>

I don't believe the first xml sample that you have listed below is properly
formatted (although possibly meaning the same thing as above)

To get and set the id's in a more friendly format you can try
UML2Util.getXMIIdentifier();

Have a look at ConvertModelAction to see how this is used.

- James.
