Java class : This is the method where i created the dropdownchoice object for select menu and add it to the form. In this method adding the projects list to the billableProjectsList
public class ReportCriteria implements Serializable {
private static final long serialVersionUID = xxxxxxxxxL;
private ReportCriteria selectedBillableProject;
public ReportCriteria getSelectedBillableProject() {
return selectedBillableProject;
}
public void setSelectedBillableProject(ReportCriteria selectedBillableProject) {
this.selectedBillableProject = selectedBillableProject;
}
}
private Form<ReportCriteria> createCriteriaPanel(String id,
IModel<ReportCriteria> model) {
SelectionForm form = new SelectionForm(id, model);
ReportCriteria criteria = (ReportCriteria) getDefaultModelObject();
List<Project> billableProjects = ProjectUtil.filterBillable(allProjects);
IModel<Project> dropdownModel = new
PropertyModel<Project(criteria,"selectedBillableProject");
DropDownChoice<Project> billableProjectsList = new DropDownChoice<>(
"projectsList",
dropdownModel,
billableProjects,
new ChoiceRenderer<Project>("fullNameWithCustomer"));
billableProjectsList.setLabel(new ResourceModel("printMonth.billable"));
form.add(billableProjectsList);
System.out.println("selectedBillableProject --- >"
+billableProjectsList.getModelObject()
+"value is --->"
+criteria.getSelectedBillableProject());
}
Html file code : This html file is for select menu display .
<td style="padding-left: 5px">
<strong>
<wicket:message key="printMonth.billable"/>
</strong><br/>
<p style="border-top: solid 1px white;margin:0 0 5px 0;padding:0">
<select wicket:id="projectsList"></select>
</p>
</td>
Error : This error is resulted once i select the dropdown value from the list . I have created the variable selectedBillableObject in ReportCriteria class and have added the setter and getter. But i am unable to convert it in this method to add it to form since it is type casting issue . But when i tried to print the value in selectedBillablePorject , its is null .

What is
new PropertyModel<Test>(this," ");
?
PropertyModel is used to read/write object's member fields. I am pretty sure Java syntax does not allow to name a member field as " ", i.e. a space character.
In addition the method that you should use is dropDownChoice.getModelObject(), not getObject().
Update:
public class ReportCriteria implements Serializable {
private static final long serialVersionUID = xxxxxxxxxL;
private ReportCriteria selectedBillableProject;
selectedBillableProject has to be a Project, not ReportCriteria.
