How to set a date on backing model obj from contents of drop down lists?

[jmorgan-2]

Hi all,

Sorry for the potentially noobish question, but I'm not sure how to  
go about this in Wicket...

I need to set a Date on a form's model object by way of three drop  
down lists.  The drop downs look something like this:

Drop down 1 contents:  "Month", "January", "February", ..., "December"
Drop down 2 contents:  "Day", "1", "2", ..., "31"
Drop down 3 contents:  "Year", "2007", "2006", ..., "1907"

Clicking the Submit button on the form will save a single  
java.util.Date object on the form's backing model object based on the  
aggregate values of the three lists' selections.

Thanks for any suggestions,

Justin

One suggestion: what about having a date pojo like:

public class MyDate
{
  get/setMonth()
  get/setDay()
  get/setYear()

  public Date getDate()
  {
     // translate object state into a Date object
  }
}


Then use PropertyModel to get/set the individual fields:

Component myComponent = new WhateverComponent( "id", new
PropertyModel( myDate, "fieldOfDate" );


That should work.


Maybe more experienced people know of a more elegant way, though this
way's not so bad.


Cheers,
Dave

if you really want something that binds to the Date then create 3 models,
each adjusting the specific portion of the date, for example:

class YearModel implements IModel {
 private final IModel date;

  Object getObject() {return date.getObject().getYear();}
  void setObject(Object o) { date.getObject().setYear((Integer)o); }
   void detach() { date.detach(); }
}

That's how I would do it.
