[JBoss Seam] - getAsObject not being called - why? - jboss-user

Wednesday, 19 December 2007

here is the converter:
@Name("tst")
  | @Scope(ScopeType.APPLICATION)
  | @org.jboss.seam.annotations.faces.Converter(id="tst")
  | public class Tst implements Converter {
  | 
  | 	public Object getAsObject(FacesContext arg0, UIComponent arg1, String arg2) {
  | 		int i = 0;
  | 		return (arg2 == null || arg2.equals("") || arg2.equals("0") || 
arg2.equals("false") ? new BigDecimal(0) : new BigDecimal(1));
  | 	}
  | 
  | 	public String getAsString(FacesContext arg0, UIComponent arg1, Object arg2) {
  | 		if (arg2 instanceof Boolean)
  | 		{
  | 			return (arg2 == null || ((Boolean)arg2).equals(false) ? "N" :
"Y");
  | 		}
  | 		else
  | 			return (arg2 == null || ((BigDecimal)arg2).intValue() == 0 ? "false" :
"true");
  | 	}
  | 
  | }

Here is the xhtml:

  | 	id="globalMessages" />
  | <h:form id="caseDetailForm">
  | 	<br />
  | .
  | .
  | <td class="data">
  | 				<h:selectBooleanCheckbox 
  | 					id="hotTask" 
  | 					value="#{selectedCase.basedonhottask}"
  | 					converter="tst">
  | 				</h:selectBooleanCheckbox>
  | 			</td>
  | 
In my backing bean, the field basedonhottask is a BigDecimal and my converter should
convert it to and from Boolean to BigDecimal. 

The proble is that upon render, it calls getAsString to convert from BigDecmal to the
strings "false" or "true" depending on whether BigDecimal is 0 or 1 -
and that seems to work fine - the checkbox is populated correctly. BUT, after changing the
checkbox, on submit, it NEVER calls getAsObject - it calls getAsString again - dont know
why??? Shouldnt it calls getAsObject to convert the BooleanCheckbos back into a
BigDecimal?
If this is a bug, is there a workaround?
