Re: integrating extjs with wicket
I would be willing to contribute to this project, but I don't have the
knowledge of Wicket internals (nor ExtJS internals, really) to pull off
the core design. If somebody starts this, he/she can count on a couple
hours per week from me.

I've made some Wicket-Extjs integration tests and I haven't found any
particular issues to make them work smoothly together.
Extjs UI widgets can be created dynamically or can be attach to existing
HTML elements using the element IDs.
Following the latter approach is quite easy integrate Extjs with Wicket.
The simplest way I've tried is using a behavior to 'attach' an Extjs widget
to Wicket component.
For example:
public class ExtDateFieldBehavior extends ExtAbstractBehavior{
@Override
String getExtjsClassName() {
return "Ext.form.DateField";
}
}
public abstract class ExtAbstractBehavior extends AbstractBehavior {
/**
* Used to add all common Extjs required JavaScript and CSS resources
*/
@Override
public void bind(Component component) {
if( component == null ) throw new IllegalArgumentException("Argument
cannot be null");
component.setOutputMarkupId(true);
component.add(HeaderContributor.forCss( Extjs.Css.EXT_ALL ));
component.add(HeaderContributor.forJavaScript( Extjs.Js.EXT_BASE ));
component.add(HeaderContributor.forJavaScript(
Extjs.Js.EXT_ALL_DEBUG ));
}
abstract String getExtjsClassName();
abstract String getOptions();
@Override
public void onRendered( Component component ) {
/* create a copy of options */
Config options = new Config( config );
/* initialization */
config(component,options);
/* get the string version */
String sConfig = Extjs.serialize(options);
String extjs = "new " + getExtjsClassName() + "(" + getOptions() +
");";
//TODO log here
Response r = component.getResponse();
r.write( JavascriptUtils.SCRIPT_OPEN_TAG );
r.write( extjs );
r.write( JavascriptUtils.SCRIPT_CLOSE_TAG );
}
}
That's all!
Obviously this is just a simple test but it works and can be extended easily
for other widgets.
What I've found not trivial is to pass/define the Extjs widget
property/configuration in a easy/elegant way.
Would be interesting discuss this...

Re: CAPTCHA clarity in post 1.2.6 releaes

Re: facebook support
Can't speak for anyone but myself, but I couldn't use any solution that does not give me access to at least the lowest common denominator of data for these sites: users, groups, contacts, etc. Just about every useful application that I can think of involves mixing in with these constructs and possibly extending them with additional functionality. I'm hoping that Open Social provides access to this information in an abstract way. If it does, I might be able to shelve my current project and move right into building end user applications.

Re: OT: API to calculate distances from zip code
If you want to implement this for yourself, you need to start with two pieces: a database of zip code data including latitude/longitude, and (to make things as simple as possible) an OpenGIS extension package for your database. This gives you the ability to index on latitude/longitude and do quick lookups using a "distance" function in the WHERE clause of your query. The implementation for PostgreSQL is called PostGIS (http://www.postgis.org); if you're using some other database then you will have to find the equivalent extension on your own. I wouldn't be surprised if some high end databases have this functionality built in. Zip code databases are available from about a million different sources. I was most pleased with the offering from http://www.zipcodeworld.com, but I'm sure that I did not investigate them all. In my experience, the data is a bit shoddy in all of these collections. You may not have problems with that until you try to combine it with something like gazetteer data. In about 2,000 cases, that becomes a nightmare. If you can avoid that...do! I have an SQL INSERT script which was generated off of the September topical gazetteer and zip code databases, but with everything pulled in I believe it weighs in at something like 40MB. :-/ Tauren Mills wrote: I apologize for this being off topic, but I have a feeling some of you might have some ideas for me. I'd like to implement a feature that will search for all physical locations in my database that are within a radius of a zip code. In other words, the user enters a zip code and selects a distance from a drop down list (5 mi, 10 mi, 25 mi, 50 mi, etc.) and a list of all locations within that distance of the zip code will be displayed. You can see something similar to this at: http://www.restaurant.com/ Are there any web services out there that would simplify this task? I have been looking at the Google Geocoding API (http://www.google.com/apis/maps/documentation/services.html), but am not sure how much it will help. I could geocode locations as they are added to my database and store the lat/long, but I get fuzzy on how to proceed from there. Somehow my SQL query (using hibernate) would need to do some computation to see if the lat/long stored in the DB is within the specified radius from the lat/long of the specified zip code. I guess I mostly want to hear from others if this would be the way they would do it, or if there is some other way that would work better or be simpler. Thanks!

Re: Session Objects Approach
Another potential gotcha with detachable models is that they can make versioning/optimistic locking a bit more difficult to use. Unless you cache the base version of your entity in the detachable model and do your own version checking, the typical implementations that I have seen will happily reload and overwrite whatever version happens to be in the database at the time of a request. This means, for example, that the user might see a form that is initialized with version 1 of your object, and then update version 2 if somebody else comes along and makes changes before they submit, potentially wiping out the other user's changes. Obviously, this only affects you if you are versioning your objects. It's just a nice tidbit to have in the knowledge base...and again, you can design your detachable models around it. You just end up with a little duplication of effort, as Hibernate/JPA/etc. already does this for you elsewhere.

Re: Empty ListChoice
I believe that doing this causes the list to contain one empty, but
still selectable, element. That is what I am trying to avoid--I just
want a plain empty list. I'm starting to wonder whether empty lists are
considered to not be the "Wicket way," as it seems like it should be
easier than this. Does ListChoice *intentionally* not allow for an
empty list? I expected to find something like
"allowEmpty(boolean)"...but no dice.
I could see this being a technical issue since the whole "Choose
One"/empty item thing will cause a request parameter to be submitted
with a form, whereas an empty list would submit no parameter at
all...possibly making it difficult/impossible to determine when a null
must be applied to the model during form processing. Does that have
anything to do with it?
That aside...thanks very much for your response, Kent.

Re: How do I force evaluate in a Wizard steps condition to run?
You would probably have to subclass WizardModel, or come up with a new IWizardModel implementation completely. The former will probably suffice, unless some strategic methods are declared final. lizz wrote: I really dont want to add more steps that the ones I already have. for the case when step c is no longer valid I woild like the next button to be disabled and the finish button to be enabled. Isn't there a method for updating the button panel? Kent Tong wrote: lizz wrote: I have three wizard steps A, B and C In step B I have a drop down choice. Whether step c is valid or not depends on the selection in the drop down choice in step B. Everytime the user changes the selection in the drop down choice the wizard must be updated (the evaluate method must be run) since for some selections the next button will be disabled since step b is the last step, while for other selections c is the last step and the next button is enabled. When I'd suggest you add an artificial step D as the final step saying "You're completed the whole process". This step is always enabled. Then no matter step C should be enabled or not, the user will always see a "Next" button. Another option is try enabling wantOnSelectionChangedNotifications() to refresh the whole page.
