About managed beans and

Question

I'm trying a JSF code similar to:
<li>Number:<h:inputText value="#{contract.pk.number}" required="true" id="pk_number" /></li>
<li>Alias:<h:inputText value="#{contract.pk.alias}" required="true" id="pk_alias" /></li>The contract bean is similar to:
public class Contract implements Serializable {
    @EmbeddedId
    private Contract.PK pk;
    @Embeddable
    public static class PK implements Serializable {
        private String number;
        private String alias;
        public String getNumber() { return this.number; }
        public void setNumber(String sNumber) {...}
        public String getAlias() { return this.alias; }
        public void setAlias(String sAlias) {...}
}        The java code is generated automatically by Dal� (http://www.eclipse.org/dali/) and I can modify it as needed, while the database squema is out of my control.
I get stuck with next problem:
Whatever I input into my form a "conversion error" is returned for the pk members.
Thanks in advance for any help, hint or link!

Answer 1

I checked get/setPk were correctly defined. Still the problem persisted.
After tracing the error I found that getPk returns null, so I just added a dummy initializer for pk after which it all works correctly (myfaces implementation bug probably??? ). Just for anyone interested the working code looks like:
public class Contract implements Serializable {
    @EmbeddedId
    private Contract.PK pk = new Contract.PK();  // <- new Contract.PK() avoid the conversion error (null pointer exception).
    @Embeddable
    public static class PK implements Serializable {
        private String number;
        private String alias;
        public String getNumber() { return this.number; }
        public void setNumber(String sNumber) {...}
        public String getAlias() { return this.alias; }
        public void setAlias(String sAlias) {...}
}
