Hi Chuck
What I want to do is something like this:
<html>
<body>
<WEBOBJECT NAME=Component1></WEBOBJECT>
</body>
</html>
Component1: Component {
content = getContent;
}
public WOComponent getContent() {
ReusablePage page = pagewithName("ReusablePage");
//Do some stuff with the page
return page;
}
So the problem is that you need to "Do some stuff with the page" so
that WOSwitchComponent will not work for you? I am still a little
confused at what WOSwitchComponent or WOComponentContent is lacking.
I just want to know if it's possible to do something like this, if
don't I suppose I'll have to use bindings in the ReusablePage,
I _think_ it is possible to do what you need.
if that is the case I have another question, where is the best
place to clean/initialize variables in reusable components, I use
to do that in the awake method, for example:
public void awake() {
super.awake();
if (((Boolean)valueForBinding("clear")).booleanValue()) {
//Clear/Initialize some variables
}
}
Does reusable mean stateless? awake() works for both stateless and
stateful components, but for stateless ones, you need to implement
reset() to set all the values back to null.
I also do not / would not use a binding like clear as shown above. I
tend to use lazy initialization like this:
public void clear() {
if (clear == null) {
clear = (Boolean)valueForBinding("clear");
}
return clear == null ? false : clear.booleanValue();
}
Then, if this value needs to get updated, in awake() or reset,
public void awake() {
super.awake();
clear = null;
}
Does any of that help?

Hi List,
I have a doubt, is there a way to create a new instance of a
WOComponent and then bind it to some component, a kind of
WOSwitchComponent but with a different instance of the
WOComponent each time?
Thanks in advanced.
