Easy question : Problem submitting form with double value.

[valatharv]

I have a form with text field (datatype double) which can be multiple.
I need to provide validation that this field can only be double and cannot be null, once "Save" button is clicked on submitting the form.
I cannot use a4j / onblur as screen is complex and this can be multiple textfields.

Issue :
When I fill this field as varchar or leave it null. On Clicking "Save" (it calls persist) nothing happens, page is not submitted and
I can't even see the SOP as given in xxxxHome.persist().

Please suggest how can I handle this.

<ui:repeat value="#{treatmentHome.xxxx}" var="itreat">
     <h:inputText value="#{itreat.treatmentConcentration}"/>
     ... THIS IS DYNAMIC AND CAN BE MULTIPLE
</ui:repeat>

public String persist(){          
          System.out.println("Persist ENTERED");
          .....
          return super.persist();
}

@Entity(name = "Treatment")
public class Treatment implements Equals, HashCode, ToString {
          protected double treatmentConcentration;
          @Basic
          @Column(name = "TREATMENTCONCENTRATION")
          public double getTreatmentConcentration() {
               return treatmentConcentration;
          }
}

Try this

<h:inputText value="#{itreat.treatmentConcentration}" required="true">
   <f:converter id="javax.faces.Double"/>
</h:inputText>

You can Hibernate validator with your entities.

I tried as suggested, issue is same "When I fill this field as varchar or leave it null. On Clicking "Save" (it calls persist) nothing happens, page is not submitted and
I can't even see the SOP as given in xxxxHome.persist()."

I checked "persistence-dev.xml" "hibernate.hbm2ddl.auto" entry was missing, so I added this "<property name="hibernate.hbm2ddl.auto" value="validate"/>" to persistence-dev.xml

Now, when I restart Jboss, I am getting this error..
-------------------------
[ServiceController] Problem starting service persistence.units:ear=appSeam.ear,jar=appSeam.jar,unitName=appSeam
javax.persistence.PersistenceException: org.hibernate.HibernateException: Wrong column type: TREATMENTCONCENTRATION, expected: double precision
-------------------------

I am missing some basic settings.

This is entity.
@Entity(name = "Treatment")
public class Treatment implements Equals, HashCode, ToString {
  protected double treatmentConcentration;
  @Basic
  @Column(name = "TREATMENTCONCENTRATION")
  public double getTreatmentConcentration() {
   return treatmentConcentration;
  }
}

If you are using hibernate then you should leverage hibernate validator.

@Entity(name = "Treatment")
public class Treatment implements Equals, HashCode, ToString {
  
  protected double treatmentConcentration;
  
  @NotNull
  @Column(name = "TREATMENTCONCENTRATION", nullable = false)
  public double getTreatmentConcentration() {
   return treatmentConcentration;
  }
}

In xhtml wrap your form fields with s:validate.

<s:validate>
  <input type="text" value="#{itreat.treatmentConcentration}"/>
</s:validate> 

Also, add h:messages to see the error message.

[valatharv]

<s:validate>
<h:inputText value="#{itreat.treatmentConcentration}" requiredMessage="Please enter as number">                                  
</h:inputText>
</s:validate>

Gives exception on page loadd itself as :

Caused by: com.sun.facelets.tag.TagException: /xxxxEdit.xhtml @324,37 <s:validate> Parent not an instance of EditableValueHolder: com.sun.facelets.component.UIRepeat@1e7e7e8

I can help you better if I can see your xhtml file.
