How to repeat node execution N times after fail?

[enpx]

Hi,

Suppose, I have this node:

<node name="create account">
 <action class="org.jbpm.tutorial.mytest.CreateContract"/>
 <transition to="next"/>
</node>

What is the right way to repeat org.jbpm.tutorial.mytest.CreateContract execution N times after fail?

I see only this way: implementing descision node after node described above and select transition by reading context variable written by described node. But this way is ugly, because every node in my workflow must be repeated on fail.

Is there another way?

does createcontract know itself failed or not?if it does,add a transition to createcontract and pick that transition when it failed.

How need I change jPDL code? Is this right:

<node name="create account">
 <action class="org.jbpm.tutorial.mytest.CreateContract"/>
 <transition name="next" to="next"/>
 <transition name="same" to="create account"/>
</node>

Suppose, CreateContract handler can setup context variable to distinct success or fail. How can I pick it up and select transition from jPDL code?

Is it possible to avoid doing this in every node by hand and setup this behaviour for every node in more general way?

createaccount handler pick transition up directly like below

Token token = executionContext.getToken();
token.signal("transition name");
