Re: isRequired: Use function instead of boolean
Ok, so I left out the detail that I have an AbstractPredicate in my environment that implements Predicate and Serializable. I honestly don't dare if it is Predicate or not, just that some Class is able to execute the function. I chose Predicate in my environment because I use commons-collections, it was already written, and it already had a number of useful, standard Predicates defined. No need to re-invent the wheel.

Re: session jumping?
We are not using any system like that. We are using the wicket-auth package with DataBinder. The userId is stored in the Wicket Session, which is thread-local. Whenever the current user is requested, it always goes through the Wicket Session object. Now that you mention thread-local, and to add another twist, this problem does not happen when our users stay in the strictly wicket part of our application. Instead, it appears to happen when crossing the wicket/legacy bounds. Even though the legacy pages are literally loaded inside of a wicket page, I wonder if there is a problem with cleaning up the thread/session... jwcarman wrote: What are you using to login?

Re: session jumping?
I moved 1.3-SNAPSHOT and still the same problem. I now see that it is the WicketURLDecoder that is causing the problem. It is prematurely decoding my **parameter** Here is the URL: /jspfs/legacyUrl/peerReview%2Fpr_start.jsp where jspfs is the Wicket mount legacyUrl is the parm name peerReview%2Fpr_start.jsp is the parm VALUE, it needs to stay encoded! instead, it becomes /jspfs/legacyUrl/peerReview/pr_start.jsp which fails to match the serveltPath on line 184 of ServletWebRequest.

Nope, that didn't help. I did identify another use case. When the grid is hidden via javascript, the error is thrown as well. I have attached another quickstart with this additional scenario.

Thanks, that's the right idea, but how can I use that to affect the client? It does not receive the target object from the event. Also, it would be nice if it included which columns changed. Or better yet, add a onColumnChanged method to AbstractColumn and then have SubmitColumnStateBehavior call that method for each changed column (passing a target object so that the client can be altered as a result of the change).

[wicketstuff-dojo] Dojo SuggestionList
I suppose this question is directed at Vincent Demay (the author listed int he component)... I am attempting to use a derivative of the DojoRequestSuggestionList. As part of it's contract with the DojoRequestSuggestionListHandler it needs to implement public abstract SuggestionList getMatchingValues(String pattern) I have this all working now, but my issue is that SuggestionList is a HashMap, which does not preserve order. So, I am creating an ordered list, then transforming it to a SuggestionList per the contract, which is tossing my order. My question is: Would it not be more appropriate to have the user return a List and supply an IChoiceRenderer (like the Wicket AbstractChoice components)? Then in the respond() method of the Handler create the JSON from those two items, forgoing the SuggestionList? Since I already have my own Handler class (to overcome a problem I had using the Dojo component within an inmethod.grid component) I will adjust my respond() method accordingly. I just wanted to toss out that problem with SuggestionList so that it can be corrected in the library.

Wicket's custom serialization
I have been using Wicket's custom serialization for quite some time now. I've noticed a few oddities, but I attributed them to my own mistakes. Now, that I have got most of my code ironed out, I have been following up on the oddities. The first scenario goes like this: I have a custom authorization strategy in place that reads a predicate from the Component's metadata. If I leave the page, then simply click the back button, the Component still has a reference to the metadata item, but not it's content (in my case the predicate object is missing). I switched back to JDK serialization and it works as expected (the predicates remain attached to the metadata object). I am preparing to build a quickstart to demonstrate this issue, but I wanted to toss the issue out there in case this is something that you might already be aware of. The second scenario is a little less clear to me. I have a Page that includes an inner class that extends the AbstractFormValidator. The Page has references to TextField objects. I received an error where the stack trace implied that it was attempting to serialize the data in the model of the page's TextField references. (something like formValidator-this$0-textField-data). Shouldn't the models of the textfields have been detached prior to serialization? Also, it seems that the joda DateTime object has problems serializing (something to do with the iChronology class). I'll make sure I keep the stack traces the next time I get these errors, at the moment, they are randomly occuring.

SortingModel (IChainingModel) - AppendingListModel (IComponentAssignmentModel) - HibernateListModel (database oriented model that returns a list of items from the db, unsorted). Let's say that the base List model returns a list of ACTIVE items from the db, over time it is possible for an item to become inactive. So, if you were to view an old record, the DropdownChoice wouldn't have the (now inactive) item in it's list of choices even though the model object for the dropdownchoice would have the object. So, the AppendingListModel ensures that the object associated with a dropdownchoice is in the list, even if it didn't come from the database. In order to do that, the model needs to be IComponentAssignmentModel so that it can get access to the component (and therefore the component's modelobject). Then the SortingModel, takes the effective list and sorts it with a specified comparator. I was able to make a Model that implements IChainingModel, IComponentAssignmentModel, and IWrappedModel that follows the chain until it either encounters a IComponentAssignmentModel or exhausts the chain.

Re: how to remove 'choose one' from dropdownlist?
If it is just a matter of not wanting to see the phrase Choose One but that
you are ok with a empty value, you could use the null property value to
change the default text. There is also a null.valid property that you can
define for the case where a null value is valid (used in conjuntion with
setNullValid(true) method).
To use those properties, make a file can {you panel/page name}.properties
and add lines to it like:
null=Some default text
null.valid=Some other text

Re: Adding a label when I add a FormComponent.
If you are going to have to add extra containers anyway, you could try it the
way we do it on my project.
In the html, we add both a label and input element with wicket ids. to keep
it simple, the label's id is the same as the related component's id with
label appended to it.
Then, we have a createLabel method that takes the Component and it
automatically adds the label with the proper id.
TextField message = new TextField(message);
message.setLabel(new Model(Message));
add(message);
createFieldLabel(this, message);
protected FormComponentLabel createFieldLabel(final MarkupContainer
container, final FormComponent formComponent) {
FormComponentLabel label = new FieldLabel(formComponent.getId() +
Label,
formComponent);
container.add(label);
return label;
}
