Igor Vaynberg commented on WICKET-4:
------------------------------------
no that would be horrible. besides we already have attach()/detach() that
encapsulate the super-called check.
maybe all we do is this
mark onattach as final and tell people to move to onbeginrender
let that break sit in there for a few weeks to give people a chance to migrate,
then go back in and rework onattach
> Page.onBeginRequest() [and consequently .onAttach()] not called when form on
> page is submitted.

> Page.onBeginRequest() [and consequently .onAttach()] not called when form on
> page is submitted. Form.onBeginRequest() is not called as well. However,
> Page.onEndRequest() and Form.onEndRequest() are called correctly.
> In more detail:
> I have a page, FrontPage, and a form LoginForm on it (The form has
> defaultFormProcessing = true)
> onBeginRequest(), onEndRequest() in FrontPage, LoginForm, are overriden as
> follows:
> protected void onBeginRequest() {
> log.debug("request begin");
> ...
> super.onBeginRequest();
> }
> protected void onEndRequest() {
> super.onEndRequest();
> ...
> log.debug("request end");
> }
> So I load FrontPage, type in data into the form (that corr. to LoginForm) and
> submit form.
> The log output is as follows
> //first load of page
> DEBUG <hotline.pages.FrontPage> request begin
> ...
> DEBUG <hotline.pages.FrontPage$LoginForm> request begin
> ...
> DEBUG <hotline.pages.FrontPage> request end
> DEBUG <hotline.pages.FrontPage$LoginForm> request end
> ...
> //form submitted
> DEBUG <hotline.pages.FrontPage> request end
> DEBUG <hotline.pages.FrontPage$LoginForm> request end
