Re: DynamicWizards and Forms
Yes but they don't cover the scenario where the new wizard step is submitted even before it is displayed. Investigated this a bit further and it seems that the delegation by the model to the actual wizard step does not happen in the correct order. I'll try and recreate this with a very simple dynamic wizard and work from there.

Help with Form submission and Ajax buttons
Hi, Beginner question with Form handling: I have a panel that accepts name value pairs in text fields.On the form there is an ajax button to add a value, an ajax button to remove a value and an actual form submit button. I have a onSubmit handler for the form that actually processes the NV pairs once the user has finished. When either the plus or minus button are pressed I update the form's model and have the form rerenderd. For this to work correctly I need the form's model updated but not have the form's onSubmit handler called. Setting default form processing to false on the twoajx buttons did not work as the model was not updated correctly (NPEs thrown) I have overridden the two buttons' onSubmit() handler to set a flag (as these seem to be called before the form's onSubmit()) and check for this flag in the form's onSubmit and save or ignore the submit accordingly. Is this the right way to do this? I don't want to use another button to do the 'true' form submission as I need to have this panel embedded in a wizard as well as an ordinary page. Thanks Sumit
DropDownChoice to add new a ListView
Hello,
Recently started a wicket project and was making excellent progress till ran
into a problem with DropDownChoices. I am trying to get a DropDownChoice to add
a panel to a form when an option is selected. The DropDownChoice contains a
list of URI properties that each map to a different datatype. When a URI is
selected in the drop down the correct component (DateField, textField, checkbox
etc) needs to be added to the form to edit the property value. I am using
fragments to actually render the right component for the datatype (as specified
in the Bean editor example).
My DropDownChoice does the following:
protected boolean wantOnSelectionChangedNotifications() {
return true;
}
protected void onSelectionChanged(final URI newSelection) {
remove(dropdownChoice)
add(new BagValueFormPanel(getComponentFactoryForURI(newSelection))
}
The BagValueFormPanel has a supporting model that adds edit components in a
ListView along with a + symbol to add more components.
Unfortunately my list view panel does not get all the list items rendered. When
running the BagValueFormPanel unit test, I get the following debug tree:
INFO BaseWicketTester - path form:panel
wicketclient.components.form.BagValueFormPanel [[= null amp;amp;]]
INFO BaseWicketTester - path form:panel:valuesList
org.apache.wicket.markup.html.list.ListView [[= null amp;amp;]]
INFO BaseWicketTester - path form:panel:valuesList:0
org.apache.wicket.markup.html.list.ListItem [= null amp;amp;]
INFO BaseWicketTester - path form:panel:valuesList:0:valueFragment
org.apache.wicket.markup.html.panel.Fragment[]
INFO BaseWicketTester - path form:panel:valuesList:0:valueFragment:value
wicketclient.panels.search.QueryElementPanel[= null amp;amp;]
INFO BaseWicketTester - path

org.apache.wicket.markup.html.form.TextField[]
INFO BaseWicketTester - path
form:panel:valuesList:0:valueFragment:value:booleanOp
org.apache.wicket.markup.html.form.DropDownChoice [amp;amp;]
But when running the test for the dynamic DropDownChoice panel where the
selection is made to one of the list choices, I get the following tree
(form:panel:filterParameterPanel:valuesList is the matching component):
INFO BaseWicketTester - path formorg.apache.wicket.markup.html.form.Form
[]
INFO BaseWicketTester - path form:panel
wicketclient.panels.search.PropertySelectComponent []
INFO BaseWicketTester - path form:panel:propertyName
org.apache.wicket.markup.html.panel.Fragment[]
INFO BaseWicketTester - path form:panel:propertyName:property
org.apache.wicket.markup.html.basic.Label [Or The Other]
INFO BaseWicketTester - path form:panel:filterParameterPanel
wicketclient.components.form.BagValueFormPanel [[= null amp;amp;]]
INFO BaseWicketTester - path form:panel:filterParameterPanel:valuesList
org.apache.wicket.markup.html.list.ListView [[= null amp;amp;]]
INFO BaseWicketTester - path form:panel:filterParameterPanel:addValue
org.apache.wicket.markup.html.form.SubmitLink []
Is this kind of dynamic addition of components possible on an
onSelectionChanged? If not I probably won't be able to add the panel in earlier
and delay the selection of the right Fragment to render the edit control right?
Cheers
Sumit
