Clob and converter/validation

[mheidt]

I am using 2.0.0CR2 and will test it against the latest nightly build once there is an error free version.

@Entity
@Table(name = "Components")
public class Components implements java.io.Serializable {
...

@Id
@GeneratedValue(strategy=GenerationType.IDENTITY)
@Column(name = "ID", unique = true, nullable = false)
public int getId() {
 return this.id;
}

@ManyToOne(fetch = FetchType.LAZY)
@JoinColumn(name = "VehicleFamilyID", nullable = false)
@NotNull
public VehicleFamilies getVehicleFamilies() {
 return this.vehicleFamilies;
}


@Column(name = "Name", nullable = false, length = 50)
@NotNull
@Length(max = 50)
public String getName() {
 return this.name;
}

@Column(name = "Description")
public Clob getDescription() {
 return this.description;
}

...

**************************

@Stateless
@Name("componentsManager")
public class ComponentsManagerBean implements ComponentsManager {
...
@In(required=false, value="newComponent") @Out(required=false, value="newComponent")
private Components newComponent;

@Factory("newComponent")
public void createNewComponent(){
 newComponent = new Components();
}

**************************

<h:form>
 <s:validateAll>
 <h:panelGrid columns="2">
 <s:span styleClass="label">#{messages['component.name']}</s:span>
 <s:decorate id="component_name">
 <h:inputText value="#{newComponent.name}" required="true" />
 <h:message for="component_name" />
 </s:decorate>

 <s:span styleClass="label">#{messages['component.description']}</s:span>
 <s:decorate id="component_description">
 <h:inputTextarea value="#{newComponent.description}" />
 <h:message for="component_description" />
 </s:decorate>

 <s:span styleClass="label">#{messages['vehicle_family']}</s:span>
 <s:decorate id="vehicle_family">
 <h:selectOneMenu
 value="#{newComponent.vehicleFamilies}"
 required="true">
 <f:selectItem
 itemLabel="#{messages['component.select_vehicle_family']}"
 itemValue="0" />
 <f:selectItems value="#{componentsManager.vehicleFamiliesList}" />
 <s:convertEntity />
 </h:selectOneMenu>
 <h:message for="vehicle_family" />
 </s:decorate>


 <f:facet name="footer">
 <h:commandLink styleClass="button" action="#{componentsManager.createComponent}" >
 <h:graphicImage url="/img/ok.gif"
 title="#{messages.add_component}"
 alt="#{messages['component.add']}"
 />
 </h:commandLink>
 </f:facet>

 </h:panelGrid>
 </s:validateAll>
</h:form>

A submit throws a
Conversion Error setting value 'user input' for 'null Converter'.

The example works, when I erase the description row.
The selectOneMenu was throwing one as well when not using
<s:convertEntity />.

But what do I have to do with Clobs?


And what about my style?
Can I get rid of the @Factory somehow?

Thanx in advance

Ok, I found the solution.

The description field needs to be defined like follows

@Lob
@Column(name = "Description")
public String getDescription() {
 return this.description;
}

and not by using the type Clob.

I'm not quite sure, but I think that seam-gen generated it the wrong way.
