Issue with Date Converter

[lfelipeas]

I'm having some issues with the Date Converter.

I have an composite-PK that is a sequence and a date. When I'm in the list page it all shows correctly. But when I try to go to the View or the Edit page, I get an error that is Value must be a date.

Debugging, I discovered that this is a Convert Exception, he's is using the default converter that is the org.jboss.seam.faces.DateConverter that is called in the method validateConvertedValue in the PageContext. So I tried to do my own converter and replace. Now I get that he cannot create converter for my attribute and I get a ClassCastException too, he can't cast String to Converter.
Oh, and I tried to pass this date attribute as a Long value too. But I get the same error that I get when using the default converter.

I ran out of options. I've searched everywhere and I don't know what to do.

I'd really appreciate if somebody could help me.
Thanks.

Hi Luis:

Show the piece of jsf code that calls the View/Edit pages.

            <s:link view="/Aditivo/#{empty from ? 'PmnAditivo' : from}.xhtml"

             propagation="#{empty from ? 'none' : 'default'}"
                      id="pmnAditivoViewId">

            #{' '}
            <s:link view="/Aditivo/PmnAditivoEdit.xhtml"

                        value="#{_pmnAditivo.id.dtInicio}"/>
            </s:link>
        </rich:column>

But I think that my list page doesn't interfere in nothing. I'll put the View page too, just in case.

<s:decorate id="dtInicio" template="layout/display.xhtml">
            <ui:define name="label">Data Início</ui:define>
            <h:outputText value="#{pmnAditivoHome.instance.id.dtInicio}"/>
        </s:decorate>
    <div class="actionButtons">
         <s:button view="/Aditivo/PmnAditivoEdit.xhtml"
                     id="edit"
                  value="Editar"/>
          <s:button view="/Aditivo/#{empty pmnAditivoFrom?'PmnAditivoList'pmnAditivoFrom}.xhtml"
                    id="done"
                 value="Fechar"/>
    </div>

[rogermorituesta.rogermori.yahoo.com]

Assuming that the following jsf code is calling the Edit, the problem is a format mismatch between the f:param and the page parameter. As you noticed, the page parameter is using the defaul date converter.

<s:link view="/Aditivo/PmnAditivoEdit.xhtml"
                   value="Editar"
             propagation="none"
                      id="pmnAditivoEdit"
                rendered="#{empty from}">
                <f:param name="pmnAditivoSqAquisicao"
                        value="#{_pmnAditivo.id.sqAquisicao}"/>
                <f:param name="pmnAditivoDtInicio"
                        value="#{_pmnAditivo.id.dtInicio}"/>
            </s:link>

There exists several flavors to fix this problem according to your specific context.

Replace all your date attributes with long

Then use a transient attribute long to date converter to do the tranlation

@Column(..)
public long getXXXDate() {
   return  XXXDate;
}

public long setXXXDate(long xxxx) {
   XXXDate = xxxx;
}

@Transient
public Date getYYYDate() {
   return  new Date(XXXDate);
}

public long setYYYDate(Date xxxx) {
   XXXDate = xxxx.getTime();
}

Match the format f:parm and page parameter using a component

In your components.xml configure the component:

<component name="DATE_FORMATTER" class="com.hersys.utils.date.DateFormatter"  auto-create="true" scope="application" >
       <property name="timeZone">#{timeZone}</property>
   </component>

The component itself:

public class DateFormatter  {
    private TimeZone timeZone;
        private DateFormat dateFormat = DateFormat.getDateTimeInstance();

    public String format(Date date) {
      if (date == null) {
          return null;
      }
      return dateFormat.format(date);
    }
        public TimeZone getTimeZone() {
                return timeZone;
        }
        public void setTimeZone(TimeZone timeZone) {
                this.timeZone = timeZone;
                dateFormat.setTimeZone(timeZone);
        }
}

In you JSF view:

<s:link view="/Aditivo/PmnAditivoEdit.xhtml"
                   value="Editar"
             propagation="none"
                      id="pmnAditivoEdit"
                rendered="#{empty from}">
                <f:param name="pmnAditivoSqAquisicao"
                        value="#{_pmnAditivo.id.sqAquisicao}"/>
                <f:param name="pmnAditivoDtInicio"
                        value="#{DATE_FORMATTER.format(_pmnAditivo.id.dtInicio)}"/>
            </s:link>

Hi Roger, thanks for your help.

Now I'm getting another problem. This time it is in the Validator.

First, I made the changes you've said, but he went to the default Converter and I got again the same Converter Exception.
So, I tried to change the value attribute in the edit.page.xml. And it is when this Validator error happens. It says: parameter is invalid: Illegal Syntax for Set Operation.

[lfelipeas]

Just to let you know, I only tried the second method of solving the problem.

I'll try the first one right now.

[lfelipeas]

I don't know if I'm using this transient attribute correctly.
I'm getting some errors. Or nothing happens, he just use the normal getter and setter.

[rogermorituesta.rogermori.yahoo.com]

Hi Luiz:

It is either solution but not both together.
I have both working, and am supposing you have something in your Edit page (xml) descriptor.

If you are using the transient you have check your embeddeId to make sure that it is using the setter and not accesing the attribure directly. Also you have to use the transient instead of the date attribute in the List (f:param) and Edit (page parameter) page as well.

The Component is less intrusive.

Can you post your code including your page XML descriptor to have more insight.

Thank you.

Roger.

I'll put my Entity and my EmbeddableID class, just in case.

Here's the Entity

@Entity
@Table(name = "PMN_ADITIVO", schema = "BL_CORP_PRJ")
public class PmnAditivo implements java.io.Serializable {

     private PmnAditivoId id;
     private short nuDiasPrazo;
     private BigDecimal vlAditivo;

public PmnAditivo() {
     }

     public PmnAditivo(PmnAditivoId id, short nuDiasPrazo, BigDecimal vlAditivo) {
          this.id = id;
          this.nuDiasPrazo = nuDiasPrazo;
          this.vlAditivo = vlAditivo;
     }

     @EmbeddedId
     @AttributeOverrides({
               @AttributeOverride(name = "sqAquisicao", column = @Column(name = "SQ_AQUISICAO", nullable = false, precision = 10, scale = 0)),
               @AttributeOverride(name = "dtInicio", column = @Column(name = "DT_INICIO", nullable = false, length = 7)) })
     @NotNull
     public PmnAditivoId getId() {
          return this.id;
     }

     public void setId(PmnAditivoId id) {
          this.id = id;
     }

     @Column(name = "NU_DIAS_PRAZO", nullable = false, precision = 3, scale = 0)
     public short getNuDiasPrazo() {
          return this.nuDiasPrazo;
     }

     public void setNuDiasPrazo(short nuDiasPrazo) {
          this.nuDiasPrazo = nuDiasPrazo;
     }

          return this.vlAditivo;
     }

     public void setVlAditivo(BigDecimal vlAditivo) {
          this.vlAditivo = vlAditivo;
     }

And here's the EmbeddableID class

@Embeddable
public class PmnAditivoId implements java.io.Serializable {

     private long sqAquisicao;
     private Date dtInicio;

     public boolean equals(Object other) {
          if ((this == other))
               return true;
          if ((other == null))
               return false;
          if (!(other instanceof PmnAditivoId))
               return false;
          PmnAditivoId castOther = (PmnAditivoId) other;

          return (this.getSqAquisicao() == castOther.getSqAquisicao())
                    && ((this.getDtInicio() == castOther.getDtInicio()) || (this

     }

     public int hashCode() {
          int result = 17;

          result = 37 * result + (int) this.getSqAquisicao();
          result = 37 * result
                    + (getDtInicio() == null ? 0 : this.getDtInicio().hashCode());
          return result;
     }

}

[rogermorituesta.rogermori.yahoo.com]

This piece of code is causing the problem:

<param name="pmnAditivoSqAquisicao" value="#{pmnAditivoHome.pmnAditivoId.sqAquisicao}"/>
<param name="pmnAditivoDtInicio" value="#{pmnAditivoHome.instance.id.dtInicio}"/>

Have in mind that the Home object will call it setId(Object x) method prior to retrieve the desired instance. So, replace it with something like this:

<param name="pmnAditivoSqAquisicao" value="#{pmnAditivoHome.sqAquisicao}"/>
<param name="pmnAditivoDtInicio" value="#{pmnAditivoHome.dtInicio}"/>

And

@name("pmnAditivoHome")
{
     ............
     CompositeId  cid = new CompositeId();


     setSqAquisicao(String yyy) {
       cid.SqAquisicao(yyy);
       setId(cid);
     }


     setDtInicio(Date xxx) {
         cid.setDtInicio(xxx);
         setId(cid);
     }
  .....  

}

[lfelipeas]

My setters are in the CompositeID object. So I'd have to something like this:

PmnAditivoId pid =  new PmnAditivoId();
     
     public void setSqAquisicao(long sqAquisicao) {
          pid.setSqAquisicao(sqAquisicao);
          setId(pid);
     }
     
     public void setDtInicio(Date dtInicio) {
          pid.setDtInicio(dtInicio);
          setId(pid);
     }

Right? Or I understood wrong?

[lfelipeas]

I don't know if this can affect something but I'm thinking that I'm getting this converter exception because the converter is trying to convert a date using the standards of the US locale while my date, the one that is going to the converter, is using the Brazil locale.

[lfelipeas]

My converter is using this:

dateStyle:      short

locale:         Locale (there's an attribute inside the Locale called language and he's using EN)

log:            LogImpl

pattern:        M/d/yyyy

timeStyle:      short

timeZone:       ZoneInfo (here there's an ID and he's using America/SaoPaulo)

transientFlag:  false

type:           date

[lfelipeas]

SOLVED!

The converter was set to convert an US date type. So added a converter modifying the pattern, the timeZone, the dateStyle and the locale. With the DATEFORMATTER, the new converter recognizes the date and successfully convert it.
