Conversion error with CalendarDataModel from Seam
I am tring to use a CalendarDataModel to display an icon within each cell of a calendar. I have a custom class that implements CalendarDataModel but I am getting an error from jsf when I try to link it to a calendar.
Here is my DataModel (almost the same as the demo site)
public class ProblemCalendarDataModel implements CalendarDataModel {
/* (non-Javadoc)
* @see org.richfaces.component.CalendarDataModel#getData(java.util.Date[])
*/
private CalendarDataModelItem[] items;
private String currentIconHtml;
private Date currentDate;
private boolean currentDisabled;
/* (non-Javadoc)
* @see org.richfaces.model.CalendarDataModel#getData(java.util.Date[])
*/
public CalendarDataModelItem[] getData(Date[] dateArray) {
if (dateArray == null) {
return null;
}
if (items==null) {
items = new CalendarDataModelItem[dateArray.length];
for (int i = 0; i < dateArray.length; i++) {
items = createDataModelItem(dateArray);
}
}
return items;
}
/**
* @param date
* @return CalendarDataModelItem for date
*/
protected CalendarDataModelItem createDataModelItem(Date date) {
CalendarDataModelItemImpl item = new CalendarDataModelItemImpl();
Map data = new HashMap();
data.put("iconHtml", "<img src=\"/img/icon-failed.gif\"/>");
Calendar c = Calendar.getInstance();
c.setTime(date);
item.setDay(c.get(Calendar.DAY_OF_MONTH));
item.setEnabled(true);
item.setStyleClass("rel-hol");
item.setData(data);
return item;
}
/* (non-Javadoc)
* @see org.richfaces.model.CalendarDataModel#getToolTip(java.util.Date)
*/
public Object getToolTip(Date date) {
// TODO Auto-generated method stub
return null;
}
/**
* @return items
*/
public CalendarDataModelItem[] getItems() {
return items;
}
/**
* @param items - setter for items
*/
public void setItems(CalendarDataModelItem[] items) {
this.items = items;
}
/**
* @param event - valueChangeEvent handling
*/
public void valueChanged(ValueChangeEvent event) {
System.out.println(event.getNewValue()+"selected");
setCurrentDate((Date)event.getNewValue());
Calendar calendar = Calendar.getInstance();
calendar.setTime(getCurrentDate());
setCurrentIconHtml((String)((HashMap)items[calendar.get(Calendar.DAY_OF_MONTH)-1].getData()).get("iconHtml"));
}
/**
* Storing changes action
*/
public void storeDayDetails() {
Calendar calendar = Calendar.getInstance();
calendar.setTime(getCurrentDate());
((HashMap)items[calendar.get(Calendar.DAY_OF_MONTH)-1].getData()).put("iconHtml", getCurrentIconHtml());
}
/**
* @return currentIconHtml
*/
public String getCurrentIconHtml() {
return currentIconHtml;
}
/**
* @param currentIconHtml
*/
public void setCurrentIconHtml(String currentIconHtml) {
this.currentIconHtml = currentIconHtml;
}
/**
* @return currentDisabled
*/
public boolean isCurrentDisabled() {
return currentDisabled;
}
/**
* @param currentDisabled
*/
public void setCurrentDisabled(boolean currentDisabled) {
this.currentDisabled = currentDisabled;
}
/**
* @return currentDate
*/
public Date getCurrentDate() {
return currentDate;
}
/**
* @param currentDate
*/
public void setCurrentDate(Date currentDate) {
this.currentDate = currentDate;
}
Then within my seam class I have:
@Out private CalendarDataModel problemsCalData = new ProblemCalendarDataModel();
And within my xhtml I have:
<rich:calendar
popup="false"
showApplyButton="false"
cellWidth="30px"
cellHeight="30px"
boundaryDatesMode="none"
showWeeksBar="false"
value="#{dashboard.problemsDate}"
showFooter="false"
mode="ajax"
reRender="problemList"
dataModel="#{problemsCalData}"
valueChangeListener="#{problemsCalData.valueChanged}"
>
<a4j:support event="onchanged" reRender="problemList"/>
<a4j:outputPanel layout="block" id="cell" style="height: 100%;">
<h:panelGrid columns="1">
<h:outputText value="{day}" style="align:center"/>
<h:outputText value="{data.iconHtml}"/>
</h:panelGrid>
</a4j:outputPanel>
</rich:calendar>
This appears to me to be very similar to the example on the richfaces site, but I am getting this exception:
java.lang.IllegalArgumentException: Cannot convert com.namemedia.sitesense.services.dashboard.model.ProblemCalendarDataModel@79134c of type class com.namemedia.sitesense.services.dashboard.model.ProblemCalendarDataModel to interface org.richfaces.model.CalendarDataModel at org.jboss.el.lang.ELSupport.coerceToType(ELSupport.java:358) at org.jboss.el.ValueExpressionImpl.getValue(ValueExpressionImpl.java:188) at com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.java:71) at org.richfaces.component.html.HtmlCalendar.getDataModel(HtmlCalendar.java:812) at org.richfaces.component.UICalendar.getPreload(UICalendar.java:608)
Is this because Seam is wrapping my object in something that is no longer an implementation CalendarDataModel? Does anyone know what I am doing wrong?
