Kind of going along with what I showed in the other thread (and some
folks here may start noting that this is partially about CFCs and
partially about Fusebox, but since the focus is on how the CFCs work I
think they will forgive us). You are getting into territory beyond
what the sample app is meant to show. My approach on this is
constantly evolving, but you would want to call a validate() method on
the Product before you run the addProduct() method, probably in the
XML but possibly in the ProductManager as well.
This whipped-up sample keeps changing, but something like this:
<fuseaction name="register" access="public">
<xfa name="processRegistration" value="processregistration" />
<invoke object="application.TOManager"
methodcall="getTO( TOType='User', checkScope=variables
)"
returnvariable="userTO"/>
<do action="v_user.registerForm" contentvariable="content.pageContent"/>
</fuseaction>
<fuseaction name="processregistration" access="public">
<invoke object="application.TOManager"
methodcall="getTO( TOType='User', values=attributes )"
returnvariable="userTO"/>
<invoke object="application.userManager"
methodcall="getUser( userTO )"
returnvariable="user"/>
<if condition="#user.validate()#">
<true>
<!-- Was the registration successful? -->
<invoke object="application.userManager"
methodcall="processRegistration( user
)"/>
<relocate url="#formatURL(
'#myFusebox.originalCircuit#.success' )#"/>
</true>
<false>
<!-- If registration was not successful, display the
registration
form again. -->
<invoke object="user"
methodcall="getValidationErrors()"
returnvariable="validationErrors" />
<do action="v_components.formatValidationErrors"
contentvariable="content.validationErrors" />
<do action="register" />
</false>
</if>
</fuseaction>
