Strange Behavior 2.0.1.GA Date Object
hey guys. i have been putting together a faily complex little app that makes use of seam 2.0.1.GA and richfaces 3.1.4. for the past few days,, i thought the issue was richfaces.. and im still not convinced its not... but i need the gurus to confirm and at least help me pin point the source of the strange behavior and describe it. So strange that until now, i couldnt even formulate the question without contradicting myself with a working example.
The problem is dealing with the rich calendar object..(and i have exhausted every resource on this already,, and even dug through some source.) code is worth a thousand words,,
a broken example.
@Local
public interface TimelineLocal {
public Date getEventDob();
public void setEventDob(Date eventdob);
...
@Stateful
@Name("timelineAction")
@Scope(ScopeType.CONVERSATION)
public class TimelineAction implements TimelineLocal, DropListener {...
/**called when we want the a save function based on a give panel
*
*/
public void eventPanelInit(int eventpanelselect, boolean eventwizard){
this.eventpanelselect = eventpanelselect;
this.eventwizard = eventwizard;
}
public void saveEvent(int panelselect){
log.info(panelselect);
switch (panelselect) {
case 0:
//do something
break;
case 1:
Events newevent = new Events();
Calendar dobcal2 = Calendar.getInstance();
dobcal2.setTime(this.eventdob);
newevent.setEventdob(this.eventdob);
.........
break;
default:
queryTimeline();
cancelEvent();
}
}
@Temporal(TemporalType.DATE)
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public Date getEventDob(){
return this.eventdob;
}
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public void setEventDob(Date eventdob){
Calendar ed = Calendar.getInstance();
ed.setTime(eventdob);
newevent.setEventday((long) ed.get(Calendar.DAY_OF_MONTH) );
newevent.setEventmonth((long) ed.get(Calendar.MONTH));
newevent.setEventyear((long) ed.get(Calendar.YEAR));
newevent.setEventxpos((long)
((ed.get(Calendar.YEAR)-byear)*YEARLEFTDEFAULT
+ ed.get(Calendar.MONTH)*MONTHWIDTH + 15 +
ed.get(Calendar.DAY_OF_MONTH)*DAYWIDTH));
this.eventdob = ed.getTime();
ed = null;
}
main xhtml and insert

thats the whole stack dump.. looked at it with firebug and everything is being sent ok,, just will not execute the saveEvent method after the bogus i can write to Date because im a moron
error message.
here is what blows my mind.
if i instantiate the entity newevent
before i load the modalPanel.. the bloody thing work fine.
some working code. (everything un touched except for adding a method and two lines of alterations to the old code.
@Stateful
@Name("timelineAction")
@Scope(ScopeType.CONVERSATION)
public class TimelineAction implements TimelineLocal, DropListener {...
/**called when we want the a save function based on a give panel
*
*/
public void eventPanelInit(int eventpanelselect, boolean eventwizard){
this.eventpanelselect = eventpanelselect;
this.eventwizard = eventwizard;
/* attention HERE*/
startTextEvent();
}
public void startTextEvent(){
this.eventdob = Calendar.getInstance().getTime();
newevent = new Events();
newevent.setEventdob(this.eventdob)
}
public void saveEvent(int panelselect){
log.info(panelselect);
switch (panelselect) {
case 0:
//do something
break;
case 1:
/*Attention HERE.. commented out*/
//Events newevent = new Events();
Calendar dobcal2 = Calendar.getInstance();
dobcal2.setTime(this.eventdob);
newevent.setEventdob(this.eventdob);
.........
break;
default:
queryTimeline();
cancelEvent();
}
}
@Temporal(TemporalType.DATE)
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public Date getEventDob(){
return this.eventdob;
}
@TransactionAttribute(TransactionAttributeType.NOT_SUPPORTED)
public void setEventDob(Date eventdob){
Calendar ed = Calendar.getInstance();
ed.setTime(eventdob);
newevent.setEventday((long) ed.get(Calendar.DAY_OF_MONTH) );
newevent.setEventmonth((long) ed.get(Calendar.MONTH));
newevent.setEventyear((long) ed.get(Calendar.YEAR));
newevent.setEventxpos((long)
((ed.get(Calendar.YEAR)-byear)*YEARLEFTDEFAULT
+ ed.get(Calendar.MONTH)*MONTHWIDTH + 15 +
ed.get(Calendar.DAY_OF_MONTH)*DAYWIDTH));
this.eventdob = ed.getTime();
ed = null;
}
no change to the xhtmls and the thing run flawlessly.
i originally thought that the problem was linked to rich:calendar directed at a session bean... i know that shouldnt matter... but it was just the observation. but at this point im not convinced.
what is happening here? is this a seam bug or a richfaces bug? if richfaces... can someone help me document it or help me understand what exactly is breaking so i can file a jira issue?
thanks for any direction.
