Hi,
I have two dropdowns. Once you select a value from the first dropdown the
second dropdown is populated using ajax. I got this to work based on the
example on wicketstuff. But when I submit the form the model is null-ed
out. I tried to remove the ajax call and then re-submit the form and the
model is fine so it looks like the ajax call is actually nulling out my
model. Here is the code.
AdminSelection adminSelection = new AdminSelection();
adminSelection.setWeek(weekStartInfo.getCurrentWeek());
adminSelection.setLeagueType("ncaa");
Form form = new Form("selectWeekForm", new
CompoundPropertyModel(adminSelection))
{
@Override
protected void onSubmit() {
//super.onSubmit();get
AdminSelection adminSelection =
(AdminSelection)getModelObject();
System.out.println(adminSelection);
getAdminSelection().setWeek(adminSelection.getWeek());
getAdminSelection().setLeagueType(adminSelection.getLeagueType());
setResponsePage(redirection);
}
};
add(form);
IModel weeks = new AbstractReadOnlyModel()
{
public Object getObject()
{
List<WeekStartInfo> weeks;
try
{
//System.out.println(selectedType.getLeagueType());
weeks =
weekStartManager.getAllWeeksFromDB(selectedType.getLeagueType());
}
catch (SystemException systemException)
{
systemException.printStackTrace();
weeks = Collections.EMPTY_LIST;
}
if (weeks == null)
{
weeks = Collections.EMPTY_LIST;
}
return weeks;
}
};
List<LeagueInfo> leagueTypes = leagueManager.getLeagueTypes();
final DropDownChoice comboChoiceDropDown = new
DropDownChoice("leagueType", new PropertyModel(this, "selectedType"),
leagueTypes,
//new
ChoiceRenderer("leagueTypeDisplay", "leagueType"));
new LeagueTypeChoiceRenderer());
comboChoiceDropDown.setRequired(true);
comboChoiceDropDown.setLabel(new Model("League Type"));
form.add(comboChoiceDropDown);
final DropDownChoice weeksDropDown = new DropDownChoice(
"week", new CompoundPropertyModel(new
WeekStartInfo()), weeks, new
ChoiceRenderer(
"selectedWeek",
"selectedWeek"));
//weeksDropDown.setRequired(true);
weeksDropDown.setOutputMarkupId(true);
form.add(weeksDropDown);
public class AdminSelection extends BaseInfo {
private String leagueType;
private int week=-1;
/**
* Constructs a <code>String</code> with all attributes
* in name = value format.
*
* @return a <code>String</code> representation
* of this object.
*/
public String toString()
{
final String TAB = " ";
String retValue = "";
retValue = "AdminSelection ( "
+ "leagueType = " + this.leagueType + TAB
+ "week = " + this.week + TAB
+ " )";
return retValue;
}
public String getLeagueType() {
return leagueType;
}
public void setLeagueType(String leagueType) {
this.leagueType = leagueType;
}
public int getWeek() {
return week;
}
public void setWeek(int week) {
this.week = week;
}
public boolean isAdminLeagueSet()
{
if (leagueType==null||leagueType.equalsIgnoreCase(""))
{
return false;
}
else
{
return true;
}
}
public void invailateAdminLeagueType()
{
leagueType=null;
}
The ObjectModel has null values in the onSubmit(). Any suggestions or
something that I am doing wrong?
