Is TrackLog your application and not a framework? If so, check here

I have changed the original way I was doing it. I have the
XMLResponse now being the shell component that has the standard
format for the way I pass back a response...
eg.
<Response code="100" message="some message">
<component content here/>
</Response>
I now have a XMLResponseComponent which is what all my REST
components subclass from. The majority of these do not require to
send back any custom content in the xml response, so I created a
helper component called XMLStandardResponse which just contains
<webobject name="xml">
</webobject>
xml: XMLResponse {
responseCode = responseCode;
responseMessage = responseMessage;
}
The actual class of this component doesn't implement these bindings
because I am overriding the template() method in the
XMLResponseComponent class...
private static WOElement _standardResponse = null;
public WOElement template() {
if (useStandardResponseFormat()) {
if (_standardResponse == null) {
_standardResponse = (new
XMLStandardResponse(context())).template();
}
return _standardResponse;
}
else {
return super.template();
}
}
I had put in debug logging into the template() method and it is
never getting called, so the only thing I can think of is that the
component creation doesn't use this method early on in the init
process.

Which version of WO? Can you paste the exception name, message,
and stack trace from the Console view in Eclipse? That will be
more helpful than a screen capture of the browser.

When I override template() I'm still getting the same stack
trace... template() is not getting called before this exception
occurring... It looks like it tries to load the .wo file before
asking itself for the template().
I can't see any other methods to override to get this to work.

Hi,
I have a component named XMLResponse that has a .wo file with an
api so that all responses from my REST interface share an
identical format. I have a subclass of XMLResponse named
CreateAccountResponse. When I try to create this page with
CreateAccountResponse response =
(CreateAccountResponse
)pageWithName(CreateAccountResponse.class.getName());
I get this
<pastedGraphic.png>
It looks like it is trying to find the .wo file for the
CreateAccountResponse component... only it doesn't exist as I
want it to use its super class's one.
Is this possible to do?
Regards,
Greg
