how to return from subflow to the state from it was executed

[kajism]

Hi,

Let's say, In my flow I have two view-states displaying employee form: create and edit. There is a drop-down for selecting companies on the form - here I want to give the user a possibility to add new company by running a subflow and when it finishes it should return back. But I have to hardcode the transition from subflow end state which could be called from create or edit...

Is there a solution for this? Must the transition after subflow be mandatory?

Thanks,
Karel

There are several ways to do it. You could have a seperate subflow-state for each of the view-states, hard-coding to which view it should return. Alternatively, you could 'remember' (in flow scope) in the parent flow whether you're viewing or editing, and use that information in a decision-state after returning from the subflow. Another option is conditional transitions in the subflow state, basically merging the decision state and the subflow state, e.g.


<subflow-state ...>
...
<transition on="$&#123;result.success and flowScope.mode=='EDIT'&#125;" to="..."/>
<transition on="$&#123;result.success and flowScope.mode=='VIEW'&#125;" to="..."/>
</subflow-state>

There are more alternatives ofcourse...

I have to do the same type of thing

Is there a way that the to="..." can be dynamic?
for instance instead of

<transition on="saved" to="availability">

something like

<transition on="saved" to="${some expression to get a state by name}">

?

I'm pretty sure dynamic values for the "to" attribute are allowed too.

After playing with it for a bit it seems that passing in a string of the state id works which is pretty cool.
so for example

you can do stuff like

<set name="flowScope.saveOrderReturnState" value="'stateToReturnTo'"/>
...
<transition on="saved" to="${flowScope.saveOrderReturnState}">

where stateToReturnTo is a stateId

<view-state id="stateToReturnTo">
...

This solves my issue.
