Re: Refresh fields from model
I think another way to do it is to call setModelObject() with the appropriate parameter on each component that needs to be updated. I chose to use the modelChanged() approach, however, because I'm using the presentation model pattern (http://martinfowler.com/eaaDev/PresentationModel.html) that populates the model properties behind the scenes. At least in my experience, I had to call modelChanged() to reflect the new values. By the way, so far, the presentation model pattern seems to work nicely with Wicket. This includes using the LoadableDetachableModel to call the presentation model to get data to populate a ListView and dereference the data for memory conservation. The result is less verbose Wicket code and the option to use the presentation model in other web frameworks. Only time will tell if this approach will scale with Wicket.

DatePicker Problems
Anyone having problems getting DatePicker to work in beta4? I get the icon, but when I click nothing happens. Probably my error, but just curious. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Configuring DatePicker
Does anyone have any examples of configuring DatePicker? I'd like to limit the minimal date, for example. I subclassed it and overrode configure() to set what I thought the Yahoo documentation said to to specify the minimal date, but to no avail. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Use of the Presentation Model Pattern
I've been experimenting with the Model-View-Presenter
(http://martinfowler.com/eaaDev/PassiveScreen.html) and the
Presentation Model
(http://martinfowler.com/eaaDev/PresentationModel.html) patterns in
Wicket. It seems like a variation of the Presentation Model approach
could work well and /may/ reduce the need for things like
LoadableDetachableModels.
In this variation, model attributes could access service objects
dynamically. For example:
class PlanSetup extends WebPage {
...
PlanSetup(String customerId) {
...
setModel(new CompoundPropertyModel(new PlanSetupPresentation(customerId))
}
...
}
class PlanSetupPresentation {
...
List getPlans() {
//would a LoadableDetachableModel still be needed to call this method?
//you could still use one if necessary.
return planService.findPlansByCustomerId(customerId)
}
void setPlanId(Integer planId) {
//this would be provided by a component in PlanSetup culled from
//the planId of a Plan that the user selected from among
//the plans returned by getPlans().
this.planId = planId
}
Plan getPlan()
//if necessary other things could be done in this method based on plan
//attributes before actually returning the plan (e.g., setting an warning
//message in another property).
this.plan = planService.findByPlanId(planId}
return plan
}
void updatePlan() {
planService.update(plan)
}
...
}
One issue would be how the presentation model accessed service objects
(e.g., planService). Perhaps it could use a proxy or a lookup
mechanism to get around serialization requirements.
If there are no real gotchas, this approach would let you write less
Wicket code and test your presentation logic without Wicket. Wicket
wouldn't need to know anything about service or application level
objects, for example. And, heaven forbid, if the corporate standards
committee makes you replace Wicket with JSF (and things like that do
happen), you still might be able to use the same presentation model.
Has anyone on the list tried something like this?

Re: Adding a Link for a Whole ListItem
I'm continuing to experiment with making a click of a row do a page refresh. I coded up a class called LinkableListView that uses a LinkableListItem, which implements ILinkListener. When the LinkableListItem's onLinkedClick() is called, LinkableListItem delegates back to LinkableListView.onClick(). Here is the what my LinkableListView generates for the 2 's. ... ... To use this component, I created a very simple page with two tables. One table contains a list of objects fetched from memory. These objects are fetched only once (at WebPage construction time). Now when I click on a row, I want the data from the LinkableListItem in the selected row to be popped over to the second table which is designed to hold only a single row. In this simple page, EVERY time I click on a row in table 1, I get the page expired message. I'm new to Wicket, so please forgive and blot out my ignorance.

Re: Adding a Link for a Whole ListItem
Thank you. I got this to work. Now I'm wondering how the ILinkListener gets registered to pick up the event. Does anything that happens to implement that interface automatically get registered?

Re: Adding a Link for a Whole ListItem
Do you also have to subclass ListView (overriding newItem()) to create an object of the ListItem subclass?

Adding a Link for a Whole ListItem
With a ListView is there a way to actually create a Link component that encompasses the whole ListItem, such that when you click anywhere on a row the onClick event is fired? I know you can do this with Ajax support, but I'm curious if you can do this using the traditional way, i.e., with a full page refresh. I don't want to add a "click here" button to my row. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
