If & Else statement in webflow inside of a view-state

Question

I've the following view-state:

<view-state id="editbestellung" view="eap/orderedit.xhtml"
    model="flowScope.entity">
    <transition on="save" to="eaporderlist" bind="true">
        <evaluate
            expression="eapBestellungDelegate.save(flowScope.entity,currentUser.name)" />
    </transition>
</view-state>

No elsewhere I set a flowScope.isToDo on true.
Now I need to check if this flowScope is true. If it is, the transition should redirect to="eapordertodolist" and if it is false, it should go to="eaporderlist".
But I only know how to set the if-statement like that:

<if test="testingMethod()" then="view-state when true" else="view-state when false" />

So how can I implement the if-statement inside of the view-state above and do the needed actions?

when are you setting `flowScope.isToDo` on true? in the save-method? — Philipp Sander, Aug 20 '13 at 09:24
No earlier. But the variable stays the whole lifetime of the flow... — , Aug 20 '13 at 09:39

Use Decision-States

Use the decision-state element as an alternative to the action-state to make a routing decision using a convenient if/else syntax. The example below shows the moreAnswersNeeded state above now implemented as a decision state instead of an action-state

Your editbestellung-state will look like this (notice that i changed the to):

<view-state id="editbestellung" view="eap/orderedit.xhtml"
    model="flowScope.entity">
    <transition on="save" to="eaporderdecision" bind="true">
        <evaluate
            expression="eapBestellungDelegate.save(flowScope.entity,currentUser.name)" />
    </transition>
</view-state>

Then you add the decision-state:

<decision-state id="eaporderdecision">
    <if test="flowScope.isToDo" then="eapordertodolist" else="eaporderlist" />
</decision-state>

Exactly this if-statement i use...? The problem is, that i already have a transition on statement. I need to change the `to=` part of this transition. And i don't know how to do that – Aug 20 '13 at 09:09
click on the link. there is a good explanaition. you will need an extra state to prcess the decision – Philipp Sander Aug 20 '13 at 09:20
@PhilippSander Just a comprehension question: is it necessary to create a method? Is the `flowScope`, which contains true / false, not enough? Can't test it currently... – Michael Schmidt Aug 20 '13 at 10:53
honestly: i'm not sure! – Philipp Sander Aug 20 '13 at 11:25
@user2413035 could you try that? – Philipp Sander Aug 20 '13 at 12:53

You do not need to create a method. You can directly test a value that is in the scope. – dbreaux Aug 20 '13 at 16:24
i edited the answer. do i need `(` and `)` around `flowScope.isToDo`? – Philipp Sander Aug 21 '13 at 07:38
No you won't need it :) Thanks a lot. It works perfect. Sorry i answer now, had school yesterday :) – Aug 22 '13 at 08:32
