How to use String on SWF2?

[aempinheiro]

Does SWF hate Strings??

My problem is that I don't understand how we use String values on webflow.

<subflow-state id="sub1" subflow="sub1">
<input name="listJsp" type="string" value="post1"/>
</subflow-state>

Why can't I just pass a string to the subflow? Do I really need to have some spring bean to hold this string?

and

<evaluate expression="utils.echo(post1)" result="flowScope.listJsp"/>

how can "post1" here be passed as string? (yes, I am really trying an echo method to pass a string to some variable... I am that desperate...)

For context I want to use the property listJsp to pass to a subflow what view to render (meaning some generic subflow).

As you probably got it by now I always get the error that the property post1 does not exist in any scope.

I am also a bit confused why I didn't find anything in the documentation about such a simple use... in fact I didn't find anyone on the internet trying to use strings anywhere on SWF... am I making the wrong approach? What am I missing?

Hi aempinheiro,

I think

<subflow-state id="sub1" subflow="sub1">
<input name="listJsp" type="string" value="post1"/>
</subflow-state>

should be replaced by something like

<subflow-state id="sub1" subflow="sub1">
<input name="listJsp" value="BindingObj.property"/>
</subflow-state>

if you want this to come up preset you could <on-entry... then set or evaluate the attribute beforehand...

HTH

Did you try using single quotes around your value? Something like:

<subflow-state id="sub1" subflow="sub1">
<input name="listJsp" type="string" value="'post1'"/>
</subflow-state>

and

<evaluate expression="utils.echo('post1')" result="flowScope.listJsp"/>

I think this is the same way you use Strings when using any kind of EL.

[aempinheiro]

<subflow-state id="sub1" subflow="sub1">
<input name="listJsp" value="BindingObj.property"/>
</subflow-state>

Well if you consider when you have a very similar subflow and you want to customize the way the view is rendered for certain occasions (and not dependent on the binding obj.) then sometimes a string parameter given by the parent flow is something that I think makes perfect sense and is logical. If I have 'n' ways of showing the same bindingObj, I do not think the best approach is to make the binding know of them... (even if it is just one...) or is it?

Did you try using single quotes around your value?

No and I'll try it tomorrow, I'll let you all know about it.

Thank you both so far!
