script dependency missing for custom facelets tag that insta

[jsutherland]

I am new to richfaces/facelets and developing a custom facelets component for my seam application.

In the encodeBegin method for my facelets component I am instantiating a rich faces component like:

HtmlDropSupport dropSupport = new HtmlDropSupport();
dropSupport.setId(id);
dropSupport.setParent(div);
dropSupport.setAcceptedTypes(object);
dropSupport.setReRender(reRenderId);
dropSupport.encodeAll(context);

This code seems to work OK and it prints the javascript for the DropSupport component on my page. However, it doesn't include the required javascript libs "DnD" and possibly others.

I noticed the DropSupportRenderer and the DropzoneRendererContributor classes; the latter containing information regarding the script dependancies I need.

My question is how do I add these script dependancies to the application? Can I do that using the FacesContext object?

Maybe if that's not possible I should just find the required javascript files include the myself?

Thanks,


Jon

Jon,

I guess that scripts should be included automatically through renderer. Are you redefining renderers?

And one more, here is: http://jira.jboss.com/jira/browse/RF-1289 the similar issue.

Nick,

Thanks for your reply, after reading the JIRA issue you referenced, I realized I made the same mistake of not adding the component to the tree properly. I needed to add the component to the children List of the parent something like:

div.getChildren().add(dropSupport);
dropSupport.setParent(div);

Now the renderer can find the component properly and all the right javascript dependencies are properly included.
