Updating Form TextField Value
Hopefully this is a simple question with a simple answer... For reasons I
can't quite grasp yet, the button to changeName doesn't change the textfield
value when I click it. However, the submit button does work to change the
value of the textfield, and setting the initial default value of the
textfield works too.
Can someone enlighten this new Wicket developer? I've tried to search for a
similar question but it seems too basic..
The form:
<form wicket:id="editForm">
<input type="text" id="name" wicket:id="name" />
<input type="submit" wicket:id="changeName" value="changeName" />
<input type="submit" wicket:id="saveButton" value="save" />
</form>
With code as such:
public class SimpleExample extends BasePage{
private String name = "defaultName";
public String getName() {return name;}
public void setName(String name) { this.name = name;}
public SimpleExample() {
Form editForm = new Form("editForm", new CompoundPropertyModel(this)) {
public void onSubmit()
{
name = "afterSubmit";
}
};
Button b = new Button("changeName") {
public void onSubmit() {
SimpleExample.this.name = "testName";
}
}.setDefaultFormProcessing(false);
TextField txtCode = new TextField("name");
editForm.add(b);
editForm.add(txtCode);
editForm.add(new Button("saveButton"));
add(editForm);
}
}
Thanks,
Tim

I think you'll want to use the <button> tag rather than the <input
type="submit> for the "changeName" button.

That was exactly it. Thanks for that explanation!

It doesn't have to do with your html input vs. button. It's because default
form processing is turned off, the form model doesn't fire that it was
changed, so the model doesn't go back to your getName() method to get it's
value.
You can add this in your button onSubmit:
getForm().modelChanged();
