Thanks for your reply!
Actually, I want to know how to implement nested components. I will show you
my scenario:
1. Requirment: A wizard that include some step to guide users complete a
task, e.g. a sale order
2. Current Implementation: I implemented two components Wizard and
WizardStep, and use them like this:
<t:wizard steps="[step1,step2,step3]">
<t:wizardStep name="step1">
step1 content
</t:wizardStep>
<t:wizardStep name="step2">
step2 content
</t:wizardStep>
<t:wizardStep name="step3">
step3 content
</t:wizardStep>
</t:wizard>
// wizard class
@Property
private WizardStep[] steps;
in this way, I need to pass WizardSteps as Property. But I want to use them
as follows:
<t:wizard>
<t:wizardStep name="step1">
step1 content
</t:wizardStep>
<t:wizardStep name="step2">
step2 content
</t:wizardStep>
<t:wizardStep name="step3">
step3 content
</t:wizardStep>
</t:wizard>
//wizard class
@Inject
private ComponentResources resources;
private WizardStep[] steps;
@SetupRender
private viod setupRender(){
//initialize steps by iterate child components
steps = initSteps();
}
//I want to use ComponentResources to get WizardSteps ids then use
getEmbeddedComponent() to get WizardStep instance.
private void initSteps() {
List<String> stepIds =
resources.getComponentModel().getEmbeddedComponentIds();
//Why stepIds is empy! so the follows codes will never execute!
steps = new WizardStep[stepIds.size())];
int i = 0;
for (String stepId: stepIds){
steps[i++] = resources.getEmbeddedComponent(stepId);
}
}
I am really confused, what's wrong with my second implementing?
Any suggestion? Thanks!
