Hi there,
I've committed changes to support portlet preview mode in jetspeed-2 and an
example, PickANumberPortlet, to apa-demo.
A portlet can implement "preview" mode by itself. In this case, Jetspeed will
invoke the portlet to render itself.
If a portlet does not implement "preview" mode but the portlet defines a
metadata in jetspeed-portlet.xml like the following example, Jetspeed will
render the preview image instead.
<portlet id="HelloPortlet">
<portlet-name>HelloPortlet</portlet-name>
<snip/>
<js:metadata
name="portlet.preview.image">/demo/images/preview/hello.png</js:metadata>
</portlet>
When those are not available, Jetspeed will render "preview not available"
image instead.
Client code can request the preview rendering by invoking portlet pipeline urls
like the following example:
http://localhost:18080/collab/portlet/?entity=demo::PickANumberPortlet&portlet=demo::PickANumberPortlet&mode=preview
As you might know, "mode" parameter is added. So, you can use other portlet
modes as well such as "help" or "view".
Kind regards,
Woonsan

Yes, I think it would be easy to add widgets.
However, I've just committed one more. I replaced the container panel tag by
div instead of table, and I wrapped the portlet item table by div. So, we don't
have to consider tr and td any more. I think it would be okay for now before we
have better widgets.

Yes. I think we need to do like that. Please review my recent changes.

As I mentioned in other email, I think it would be better to support 'preview'
custom mode and invoke a portlet with 'preview' custom mode when we need
preview page for the portlet.
If a portlet implements 'preview' custom mode, then we can just render the
output in an area. Otherwise, we can do some default handling. For example, we
can define a metadata like 'thumbnail' in jetspeed-portlet.xml...
