I was looking at the code of AutoComponentPanel and found similarities
between this and IComponentResolver. AutoComponentPanel has an
overridable getMarkupComponent(ComponentTag, MarkupStream) where
IComponentResolver has resolve(MarkupContainer, MarkupStream,
ComponentTag). Can someone explain this class and its uses to me? Is it
something that I should want to use for AutoComponentPanel?
We user AutoComponentPanel as a base class for some other panels that
provide dynamic markup. Would it be better (aka the wicket-way (tm))
when AutoComponentPanel is re-written as an IComponentResolver that can
be used by the currently subclassing panels. They would then need to
implement IComponentResolver too but can call my rewritten
AutoComponentPanelAsResolverSomething in their implementing methods.
Would this be a better way to go?
How should this work when I add my resolver with
Application.getPageSettings().addComponentResolver(resolver)?
Thanks,

Hello Praveen,
Wouter Huijnink presented something similar to what you need at the
wicket meetup in Amsterdam. We generate html dynamically from xml,
using xslt. A component called AutoComponentPanel parses the html and
adds components to the hierarchy accordingly. This is actually a
two-step process. The first step is telling wicket you want to supply
markup yourself instead of letting wicket read it from the
corresponding html file. You can do this by implementing
IMarkupResourceStreamProvider and if applicable also
IMarkupCacheKeyProvider. Then you need to parse the markup stream and
add components.
If you're interested I can send the AutoComponentPanel code. It still
needs some work to make it shine, but we plan to open source it anyway
as part of a wicket-based QTI framework.
PS. Unfortunately Wouter's slides aren't uploaded yet.

thanks Johan for your reply. I did take look into your slides.
We can generate HTML pages, we have no issue with it. But how to display
this newly created HTML pages which only exists in memory, there is no
physical file. And also to navigate to this new HTML page.
For example If I create a simple HTML page at runtime like below
test.html.
How to display it and navigate to it. As it also requires corresponding
test.java. This is simple one. But what if we have wicket:Ids we need
construct the Java files with all the action listener also.
test.html
<html>
<body>
<h1>Hello world! </h1>
</body>
<html>

Look at he slides i put on of the presentation that i did for the
wicket user group in the netherlands

I looked into the example wicketstuff-crud, this is basically in
memory
database with basic CRUD operation. this is not what exactly I am
looking.
Let me restate the question. We have application where in user can
create
a
webpages using web designer by drag-n-drop where is html elements like
text,
image, selection box, combo box and save it in DB.
It will be Json format parse it to POJO and store in DB. for example
Image
object looks like this
which has got position, style, etc .
[{"position":({left:60, top:40}),
"size":({width:100,height:80}),
"positionTop":40,"positionLeft":60,"sizeWidth":100,"sizeHeight":80,
"cssClass":"",
"style":"left:60px;top:40px;width:100px;height:80px;",
]}}]})
Now we need to read from the DB and reconstruct the same Image
object has
a
html page. We can construct the above object with HTML tags.
But the question is how to display this html pages, since it exists
only
in
memory and also how to navigate to this newly created page.

This
page only exists in memory(session/cache) and there is no physical

so
how to generate such page and corresponding java class. How this can
be
done
for static elements like image and text versus dynamically for form
submit.
Also how to navigate to this newly generated html page.
