Hello guys and girls,

I have this page: 


...
<h:form id="editImageSetForm">
            <h:dataTable value="#{images}" var="image">
                <h:column>
                    <img src="#{image.getThumb().getUrl()}" /><br/>
                    <a:commandLink value="Mark as MAIN" rendered="#{not imageSetView.isMainImage(image.id)}" action="#{imageSetView.makeMainImage(image)}" reRender="currentImageSetA" />
                </h:column>
            </h:dataTable>
        </h:form>
...

and this bean - ImageSetViewBean.java 


@Stateful
@AutoCreate
@Name("imageSetView")
@Scope(ScopeType.CONVERSATION)
public class ImageSetViewBean implements LocalImageSetView {
...
    public void makeMainImage(Image image) {
        currentImageSet.setMainImage(image);
        imageSetDAO.update(currentImageSet);
        FacesMessages.instance().add("Image " + image + " setted as main image.");
    }
    
    public Boolean isMainImage(Long imageId) {
        log.info("isMainImage(): got imageId= #0", imageId);
        Image image = imageDAO.findImageById(imageId);
        if(image.equals(currentImageSet.getMainImage())) <---- NullPointerException here
            return true;
        return false;
    }
...
}

I am not able to send method parameters taken from the dataTable inside the rendered attribute tag EL value.

If I remove the render condition, and simply display in page the output of the isMainImage() method, it works perfectly displaying true or false. Also, the makeMainImage(Image image) works fine. It is just the methods from the rendered tag that are causing me problems and throwing the following exceptions.

It is obvious (i think :p ) that during render phase, JSF is not able to retrieve the method parameters sent in that EL. But what is the workaround for this problem?

Thank you in advance for any hint!

This is the exception stack:

Why not take that image out of the list before you send it to the page?

In whatever Bean you get #{images} from you could inject the currentImageSet and then just remove the main image once you have queried the database.

Should perform better too.

Cheers,

Damian.

Hello Damian,

Thank you for your reply. You are right, I can take this approach, and it should perform better.

But I was wondering, is this a JBoss EL limitation? Not to be able to pass method parameters inside the rendered attribute of any tag?

Thanks,

Bogdan.
