boolean property not binding

sbozdag Oct 9, 2007 6:53 PM

Hi,

I have a page as below:

 <!-- mypage.xhtml -->

 <ice:form id="someFormId">
 ...
 <h:selectBooleanCheckbox id="containsHeader"
 value="#{bean.checked}"/>
 ...
 </ice:form>

I am trying to show a check box component on the page. And here is my "stateful" session bean,

@Stateful
@Scope(ScopeType.SESSION)
@Name("bean")
public class MyBean implements Serializable, IMyBean{

 @In boolean checked;
 // other properties
 public String someAction() {
 //...
 return "someOutcome";
 }

 @Remove
 public void destroy() {
 }
}

I am getting this error message while trying to load mypage.xhtml given above.

Exception during request processing:
Caused by javax.faces.FacesException with message: "Problem in renderResponse: javax.el.PropertyNotFoundException: /mypage.xhtml @35,74 value="#{bean.checked}": Property 'checked' not found on type org.javassist.tmp.java.lang.Object_$$_javassist_2"

What do you think that why the error occurs?

Thanks

You need to add getters and setter for checked to both MyBean and IMyBean.

Thanks. I added getters and setters methods to both files by now. Error message has changed to:

Exception during request processing:
Caused by javax.faces.FacesException with message: "Problem in renderResponse: javax.el.ELException: /mypage.xhtml @35,75 value="#{bean.checked}": Error reading 'checked' on type org.javassist.tmp.java.lang.Object_$$_javassist_2"

Hmm... There are also more stack trace lines. Do they make any sense?

swd847 Oct 10, 2007 6:00 AM (in response to sbozdag)

The problem is with the @In, your component 'checked' cannot be injected. try @In(create=true) and you might see some improvement.

I must admit though I have never tried to inject a primitive, I have a feeling that this will not work.

sbozdag Oct 10, 2007 6:23 AM (in response to sbozdag)

Thanks anyway. Although I tried @In(create=true), it did not work for me..

So, I think that this should be a very trivial thing for framework to work with primitive data types.

What should I try next do you think?

swd847 Oct 10, 2007 6:56 AM (in response to sbozdag)

Why do you want a scoped boolean anyway? It seems a bit odd to me.

Are you sure you actually want to inject this boolean and not just have it bound to the check box on the page? If this is the case then remove the @In annotation and everything should work ok.

8. Re: boolean property not binding

sbozdag Oct 10, 2007 7:41 AM (in response to sbozdag)

probably you're right! thanks.

I now don't use @In annotation and it works. I am new to seam and trying to realize when to use @In and @Out ? Since I am not a pragmatic programmer yet, I sometimes program blindly. Could you please tell me the idea of @In and @Out in brief? (if you have enough time to type a few words) AFAIK, seam is not ejb3. So I feel a little bit inconfident while programming in seam.

thanks.

swd847 Oct 10, 2007 7:50 AM (in response to sbozdag)

You need to read the docs and look at the examples. Dependency injection of seam components is pretty core to the framework, and it is a bit to much to re-type here.

wquraishi Oct 10, 2007 2:42 PM (in response to sbozdag)

i had to change my model to get boolean values to work right, by specifying the actual column type:

@Column(updatable = true, name = "featured_listing", columnDefinition = "TINYINT")
public boolean isFeaturedListing() {
return featuredListing;
}
