@Embeddable question

[anescu]

Hi,

We're trying to use an @Embeddable class in our project. It's a seam generated project, but we keep our entities and modify the views as needed.

So, we have a ABC @Embeddable class which has one field

private String name;

And this class is embedded into another, XYZ.

On the interface i have a field:

<s:decorate id="ABCNameDecoration" template="layout/edit.xhtml">
 <ui:define name="label"><h:outputText value="#{messages['XYZ.ABCName.label']}" /></ui:define>
 <h:inputText id="ABCName"
 size="100"
 maxlength="100"
 value="#{xyzHome.instance.ABC.name}" title="#{messages['XYZ.ABCName.tooltip']}">
 <a:support event="onblur" reRender="ABCNameDecoration"/>
 </h:inputText>
</s:decorate>

The page renders ok, but when i try to edit/add an entity and put some value into this field I get a validation error:

value could not be converted to the expected type

No error shows up in the log, even on debug mode.

I browsed the forum and found somewhere something about needing a converter for this entity. I also found some examples on how to build a custom JSF converter. So, my questions are:
1) is there a doc on how to do custom converters on seam (what needs to be configured and so on)
2) If my ABC class has 5 fields, all rendered on the page of the owing entity (XYZ) as separate fields, do I need 5 converters, one for each field????
Tnx, I wait for your reply...

Have you declared the ABC as follows?:

public class XYZ {
...
private ABC abc = new ABC();

...
getters/setters
}

In this case "abc" should be referenced in the view, not ABC.

HTH.

Yes, I just tried and the same problem.
i also tried this one: I manually inserted the value into the DB (in xyz_abc_name field), so this one works like this, after that i deleted the value from the field and updated, all works ok.

Is possible I need to set not null value on the field in the constructor???

Correction:

It works to insert a new entity XYZ. But i have a script which inserts some rows into xyz tables without the xyz_abc_name field. If i select one of these entities and want to update the abc.name field to something then i get a validation error.

Anybody any idea how to solve this one?

[fernando_jmt]

I make a mistake in my last post, the code shoul be:

public class XYZ {
...
@Embedded
private ABC abc = new ABC();

...
getters/setters
}

And your ABC must have @Embeddable at type level.

do you have it in this way?

[anescu]

Yes, i have them both. Earlier i had only the @Embeddable on class ABC, but i saw the @Embedded annotation in another post and used it.

So the insert works, but the update of some already inserted entities does not.
