I found performParentAction or valueForKeyPath can be used to solve the
problem.

Subject: Re: Custom SubmitButton
You have to be careful with action methods and re-usable components.
Practical WebObjects describes how to do this.
How are you implementing MyReusableComponentWithSubmitButton?

I need to make several reusable components that handle custom bindings

I found the idea is ok as long as the reusable components not include
submitbutton.
Say I have a page called MyPage
MyPage.html
...
<webobject name=MyForm>
<webobject name=MyReusableComponentWithSubmitButton></webobject>
</webobject>
....
MyPage.wod
...
MyForm: WOForm {}
MyReusableComponentWithSubmitButton { action = nextStep; infoDict =
ctrlEO.infoDictionary; user = session.sessionUser; }
....
MyPage.java
.....
public WOComponent nextStep() {
........
if(dataCheckOK()) {
return pageWithName("NextStep");
}
return null;
}
When click the submitbutton inside of MyReusableComponentWithSubmitButton,
no matter dataCheckOK() returns what, it'll never bring me to the NextStep
page.
The reason is that the action is fired in the subcomponent
request-response loop, even it triggers MyPage's method nextStep(), it
will not alter the page level response generator!
My question is: how to make the submitbutton inside of the subcomponent
behavor as if it placed directly at page level?
Thanks for any thoughts!
