Re: Anemic domain model and are @SpringBean's compatible with the solution in "Spring 2.0 vs. the Anemic Domain Model"?
I use the same setup as you, but I add the use of the
OpenEntityManagerInViewFilter. I still use only Spring services from within
Wicket (as much as possible), but the domain objects can be as full featured
as needed because a Hibernate session is always open when Wicket is using
the services.

Or, another way,
IChoiceRenderer cr = new IChoiceRenderer(){
public Object getDisplayValue(FixedCharges fixedCharges)
{
return fixedCharges.getDescription() + " - " +
fixedCharges.getValue();
}
public String getIdValue(FixedCharges fixedCharges, int index)

inmethod datagrid: how to contribute?
We have been using the inmethod datagrid in our latest project. (1.4 SNAPSHOT from wicketstuff-core) We have some bugs (or issues, at least) to report and might have some contributions. I don't see a Jira project on the wicketstuff jira nor is there info on the wicketstuff wiki. Is there a way to contribute or communicate with the maintainers? Will

Taha, I've tried playing with your HibernateValidator. It seems necessary to add it to each form field. If I add it simply to the form, the validation behavior doesn't happen. Am I missing something?

In the archives, back in 2007, I see a lot of discussion about Hibernate/JPA
validator and Wicket, but I can't find if there was any result from those
discussions. Did anything come of it?

adding multiple onchange behaviors to DDC

I'm trying to write a class that extends OnChangeAjaxBehavior. Is there a way, in the update method, to get the component to which the behavior has been added? I just don't see how. Should it just be added via the constructor? component.add(new MyOnChangeAjaxBehavior(component)); This doesn't seem right to me, but maybe that's the way? Thanks for any info, Will

inmethod datagrid, ajax interactions between cells
I'm working with the inmethod datagrid. I would like to set up some ajax interactions between cells within a row. For example, between two EditablePropertyColumns, if the user starts typing in one cell, having ajax blank out the other. There are a lot of methods one can override which provide the rowModel as an argument. But I don't see how to get access to all the components of a row. And I'm not sure what to do even if I did get access to the components in a row. Has anyone tried to set up such ajax interaction between cells? Thanks, Will
inmethod datagrid with a DropDownChoice cell
I'm working with the inmethod datagrid. The grid is editable, and I have it working just as the examples show, with a couple of cells that contain text. As in the examples, clicking on a row changes some cells into TextField components that can be edited. Now I would like to create a cell that displays text, but when the row is clicked the cell turns into a DropDownChoice component. I've tried to mimic the EditablePropertyColumn and the TextFieldPanel with my own EditableDropDownPropertyColumn and a DropDownPanel. These render fine and let me select from the dropdown, but things go wrong when I press the submit icon. I get an exception: "Attempt to set model object on null model of component" If/When I have time I will make a quickstart, but If anyone already has this kind of thing working I would appreciate very much seeing the code.

AH, yes. Thanks. And the place to do it is in the SubmitCancelColumn :
columns.add(new SubmitCancelColumn("esd", new Model("Edit"))
{
@Override
protected void onError(AjaxRequestTarget target, IModel
rowModel, WebMarkupContainer rowComponent)
{
target.addComponent(feedback);
super.onError(target, rowModel, rowComponent);
}
});
inmethod datagrid, validation, and feedback
The examples for an editable inmethod datagrid show how to add validation when adding a new column. The "firstName" and "lastName" components are required. (component.setReqired(true)) And, indeed, if one edits a first name and blanks it out and press the "save" icon, the row is not updated. But no feedback is shown. I can see in the debug messages, when the WebSession goes to clean up the feedback messages, that there are messages that haven't been displayed. So we know that the validation works and produces error messages, but the Ajax nature of the datagrid row edit doesn't allow for the display of the error messages. So, how would one show those error messages? And where would such code get hooked in? Will

Perhaps it's because I'm still relatively new to Wicket and very new to the Ajax stuff in Wicket. As I've said, I don't see how to add or delete rows to the datagrid. But also I don't see in the examples how to actually update the database with any edited values. Nor do I see, once a row is selected, how to get that selected row and do something with it. So, I'm pretty clueless, which makes it hard to help me, but I'd appreciate any info or pointers. Will

getting component parent
Using 1.3. I have a panel which needs to create different internal components depending on who it's parent is. However, calling getParent() in the constructor gives me null. I can make a constuctor that passes in the parent. But I wonder if there is a different way. Is there some other point where I could call getParent(), get the parent, and then construct the components for the panel?

Re: general question on dynamic pages
Thanks for the reply. I appreciate the desirability of thinking more OO and less request/response. Even so, the Wicket Page class is still modeling an html page. Where is the "onBeforeLoad" functionality of a web page? Is "onBeforeRender" the equivalent? With regard to the Login/Welcome example, I have a problem with the Login's page's mutator methods being called in the onClick() in the Welcome page. Your scenario requires that Welcome know too much about Login. If Welcome and Login depend on the same model, and Welcome changes the model, then when control is passed back to Login it should be able to act on that change without the need for Welcome to know about it. I don't see yet where Login has the opportunity to act on the model change before the page is displayed. Again, is this where onBeforeRender() comes in? Or some other method? Thanks, again, Will Ryan Holmes wrote: I think one of the keys to getting comfortable with Wicket is to think in terms of plain objects rather than requests, pages, etc. For example, if you were working with a Person object rather than a Login page and you wanted to provide some way of modifying that Person object, you would just add a mutator method to the Person class, right? Well, it's the same thing in Wicket. Just add a method to the Login page class that performs whatever modifications you want. This method might update the models for components on that page, change the visibility of components, replace components with other components, just to name a few possibilities. In the example you gave, this method (the Login page's mutator method) would be called from the onClick() method in the Welcome page's Link, just before calling setResponsePage(). hth, -Ryan On Jul 27, 2007, at 11:20 AM, Will Jaynes wrote: I'm new to Wicket and struggling a bit. I feel I may be stuck in old thinking of action frameworks like Struts or Spring MVC. All of the examples I have looked at so far do all the work of creating and adding components for a page (or panel) in the constructor of the page. Are there other places where this work can be done? In a dynamic page, I can imagine that between the time a page class is constructed and when the page is displayed, there might be changes that have to be made. Where could this code be placed? For example, the Pro Wicket book (around page 32) has an example of a Login and a Welcome page. The Welcome page constructor takes a reference to Login.this, so that a link back to the Login page takes you back to the same instance of the Login page. In this scenario, when the link is clicked and the response page is set to the existing Login page, where is the opportunity to change the Login page, if required? In Struts I would have the Struts action. Here, I'm not so sure. Thanks for any info.
