wicket 1.5 xml/doctype/html header: xhtml vs html5
From https://cwiki.apache.org/WICKET/wickets-xhtml-tags.html, are these still the desired tags for the start of a wicket html file? ?xml version=1.0 encoding=UTF-8? html xmlns=http://www.w3.org/1999/xhtml; xmlns:wicket=http://wicket.apache.org/dtds.data/wicket-xhtml1.4-strict.dtd; xml:lang=en lang=en and lt;!DOCTYPE html PUBLIC quot;-//W3C//DTD XHTML 1.0 Strict//ENquot; quot;http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtdquot;gt; html xmlns=http://www.w3.org/1999/xhtml; xmlns:wicket=http://wicket.apache.org/dtds.data/wicket-xhtml1.3-strict.dtd; xml:lang=en lang=en Of these two options, which is preferred? Why would I choose the xml start (versus DOCTYPE)? Does either choice impact the use of HTML 5?

Re: PageMap in 1.5
Let me simplify my original question. If in the past I could do this: getRequest().getPage().getPageMap().remove() a) What was the practical purpose of removing page maps from sessions (i.e., this API existed for a purpose - what was it)? b) What do I do in 1.5 to accomplish the same thing now that PageMaps are gone? I suspect this has something to do with back button support and page history. This wiki page (https://cwiki.apache.org/WICKET/caching-in-wicket-15.html) discusses caching, true. I guess what I'm looking for is a discussion of PageManager (the replacement for PageMaps). How does this work in 1.5? -Doug -- View this message in context: http://apache-wicket.1842946.n4.nabble.com/PageMap-in-1-5-tp3685858p3686882.html Sent from the Users forum mailing list archive at Nabble.com. - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org
PageMap in 1.5
I'm porting this sample scala/wicket application from Wicket 1.4 to 1.5.
I've almost completely got it figured out except for this bit of code from a
class that extends RequestCycle (it does some basic
EntityManager/Transaction stuff):
override def onEndRequest =
{
super.onEndRequest()
if (em != null)
{
if (em.getTransaction().isActive()) em.getTransaction().commit()
em.close()
}
// TODO: in 1.5 page maps no longer in use - not sure why they'd want to
do this to begin with...
// TODO: ahhh, maybe to prevent hitting 'back button'?
//if (_endConversation) getRequest().getPage().getPageMap().remove()
}
The line I have commented out at the end is what I can't find an equivalent
for in Wicket 1.5.
Whether or not this is the proper way to do database stuff is really not
important to me - please don't let that distract from the question. For
those that are curious, the _endConversation flag is set in the body of a
form's onSubmit() method, after data is written to the database.
What I'm really interested in is
a) Why would someone want to remove the page map from the session in Wicket
1.4? like above Is my comment correct that it prevents hitting the back
button and re-submitting a form?
b) What is the Wicket 1.5 way of handling a situation like this? I looked
at some other related posts on these forums, but haven't found a good
description yet.
c) In general, how does page caching work in Wicket 1.5? There isn't much
on the migrating wiki page...
Thanks,
-Doug
