It
seems to me that most descriptions of Wicket that I've seen on the web focus on
two properties: the absence of configuration files and the radical
separation of HTML from Java code. (Then readers debate whether the
absence of configuration files limit flexibility and whether the use of standard
tool-friendly HTML is all that important.)
It
seems to me that Wicket evangelists should put more effort on Wicket's object
orientation. The key questions we should ask when comparing Wicket to
another component-oriented framework (e.g. Tapestry or JSF) are the
following:
(1) If the user wishes to create a panel that assembles visual
components or sub-panels that react to each others events, and which
provide/handle events to be hooked to other arbitrary components on the page,
what facility does your framework provide to package such an assembly
in a re-usable format?
(2) If I have a complex, feature-rich component that I want to use on
many web-pages, and some of the configuration choices will be set the same way
for all of them, what facility does your framework give me for creating a facade
around this component that will set these defaults for me -- so I don't have to
repeat myself on page after page?
(3) If some of the pages which use this component need it to provide
extra enhanced or specialized behavior, how does your framework make it easy for
me to create a new component that extends the properties and behavior of
the base component?
We should identify a few simple examples of such uses to contrast
Wicket's power with other frameworks' shortcomings. After the
big-deal object-orientation revolution of the late-1980s/early-1990s, it
astounds me that so many programmers can ignore the importance of
object-orientation for coding presentation
logic.
