Thanks for the laugh. Where are the irony tags?

Violates Dry:  You must repeat the component hierarchy of your widgets that
are in HTML in Java Code for no good reason.  If you move your widget around
in the html it will break the Java and you get a stack trace if you change
the nesting.  You have to keep these two files synched.  A JSP file is more
maintainable.  At least the view code is in one place.

Not previewable:  One of the supposed benefits of Wicket is a clean template
that could make pages previewable for designers.  First, we don't have
seperate designers at my company.  Second, it is better if the samer person
does development and design.  Third, if you use extends your page will not
be priviewable outside an application server running Wicket.  This supposed
benefit does not exist.

Violates MVC:  It smashes view and controller code into the same Java file.
You have code that regulates page flow and code that changes css attributes
in the same file.  Even Spring MVC had better separation of concerns.
JSP/Servlets with Spring MVC is better.

Excessively verbose and complicated:  What is a LoadableDetachableModel?
The learning curve for Wicket is immense.

Breaks POJOS:  A real POJO does not need to implement an interface or extend
a class.  Wicket forces your beans to be Serializable.  This is like using
EJBs in how it forced you to implement interfaces.

Terrible AJAX:  Compared to a few lines of jQuery AJAX is excessively
complicated and verbose in Wicket.  A lot of things like “AJAX” links should
not be done via “AJAX” at all.  Hiding a div on the client would simply be
done with JavaScript on the client.  Wicket better not require a server
request for that.  You also have no JSON support and good luck debugging any
JavaScript or AJAX in Firefox.  Instead you have to use the subpar Wicket

HTML5:  No support for HTML 5 form elements unless you upgrade to Wicket
1.5.  You will get a stack trace.  The upgrade to Wicket 1.5 is painful and
will break your code.  Good luck getting this to work with jQuery mobile.

Bad Defaults:  Most pages are stateless.  The default for Wicket is
stateful.  So if I want a decent URL and a bookmarkable page I have to mount
the page and use a bookmarkable page link with page parameters.  Using page
parameters is worse than how Spring MVC does binding.  I have to keep doing
this over and over for each page.  There is too much work involved to get a
decent stateless page with a nice URL. This should be the default.

Interferes with other libraries:  It screws up your jQuery code.  It forces
you into a restrictive way of doing web-development:  the Wicket Way.

Causes a redeploy whenever you add anything:  Maybe Java developers are used
to this, but in any other web development environment I do not need to
redeploy after adding a text box to the page.  It is completely absurd.
Only with JRebel is this alleviated.  No, embedded Jetty in debug mode still
slow.  Even a simple JSP file has hot reloading on Tomcat and if I make a
change to my view code the changes are immediately viewable in the browser
when I refresh.  This is WITHOUT JRebel.

HTTPSession Objects are not hard:  Most pages do not need state.  If you do
use HTTPSession it is simple.  Can you use a map?  Then you can use
HTTPSession.  This is less comlicated than most Wicket code.

Stateful Component based framework are a terrible idea:  Even at the
theoretical level this is a bad idea. It is a leaky abstraction over a
simple request/response cycle.  It made something simple and made it overly
complicated.  This remind me of Hibernate and ORMS.  I disagree that we
should abstract things to this level and do everything in verbose Java.
People are dropping Hibernate and going back to native SQL and Spring JDBC
template.  SQL and the relational model are easy.  Working with HTTP
requests is easy too.  What was wrong with JSPs/Servlets?  Keep it simple
stupid.  We know JSF was too complicated and it was terrible.  Spring MVC is
better and has rest support.  It just works with Spring and has great
support for the JSON Jackson mapper.
