IDataProvider for growing Result Size

[bht]

Hi,

I am seeking some help or links to documentation with IDataProvider
for DataView.

In my use case the size of the data grows while the user clicks
through list pages.

I wrote an IDataProvider implementation that progressively returns
larger values with the size() method.

However it fails due to the size growing, if the user clicks on the
last page.

That is because DataView limits itself understandably, by only
requesting as many rows as the last invocation of size() tells it are
available.

But this limitation is unnecessary.

What is needed is that it keeps filling the page until the Iterator
for IDataProvider.iterator(int first, int count) returns false with
hasNext(), or until its page is full, in that case displaying a link
to the next page, ignoring the fact that size() is no longer accurate.

I hope that an easy solution for this requirement exists as I think
that there is no conflict with out-of-the-box correct behavior.

Again, very specifically, during the same cycle, after the
underestimated size() result, the iterator may return more data than
expected, and that excess data should be consumed normally in such a
way that the user can continue moving forward to subsequent pages as
long as more data becomes available.


Many thanks!

Bernard

Class not found error when using OSGi classloader and wicket-guice integration

[Marc-Andre Houle]

Hello user group,
Just a little word to make sure this is check out.  I got a ClassNotFound
exception while working with my OSGi framework and integrating it with
Wicket-Guice.  The problem is that Wicket guice use the method Class.forName
to retrieve the class into which injection is suppose to take place.  Since
our wicket components can be in plugins and can be therefore in another
classloader, wicket-guice is not able to retrieve the class name.

I created a bug (WICKET-2530
) for this and included a subversion patch where instead of using
Class.forName, Wicket-Guice is using Classes.resolveClass and the class
resolver that is given by the user application.

I hope I didn't think something for granted and that it is not a fix that
can broke something else.

Thanks to check this issue.

Re: Strong Password Validation using Ajax (with Fallback)

[Bernhard Grünewaldt]

That's the case :)

I want to have it working with Javascript activated and without.

I am now thinking of something GWT does.
You write java and the framework translates it to ajax. (if I am not
mistaken)
It would be cool to write just one Validator in Java
that implements some behaviour and it works as ajax and without on the
serverside.

Does anybody have a tutorial or best practice for that, or will I end up
maintaining redundant code for Java and Javascript?
I am using jquery as framework if that is of concern.
But I am open for everything.

I already took a look at wiquery but haven't found a nice tutorial for my
purpose.

call setMarkupId("theSameId") in .java
you could remove the one in .html if you wish

It is little strange that _your_ (I emphasize here) software uses

how to have an html id in markup and support ajax behavior?

[Joe Hudson]

Hello,

I need a component to have an html id that I set in markup because I'm 
referencing it in other places.  I also need to have the 
setOutputMarkupId(true) on the component because I need to support ajax 
behaviors.  The problem that I am facing is that when I call 
setOutputMarkupId(true) it overrides the static id I set in the markup.  Is 
there any way I can deal with this?  Thanks.

Joe

Mistletoe's design imposes a strict separation between the data-model

designing the data-later, I started writing the presentation layer
using Wicket. It's was a very pleasant experience. Wicket just clicked
in my mind. By the way, wicket encouraged me to re-design my
