[jira] Commented: (JS2-383) Configuring portlet in PSML
[ http://issues.apache.org/jira/browse/JS2-383?page=comments#action_12332715 ]
Randy Watler commented on JS2-383:
----------------------------------
We too have this need, so I'll step up to the plate and get it on my next bug fix pass.
There is still some debate on this issue realated to SOC, (from DST):
I've thought about the need for this too. Very common requirement I think.
One solution for this kind of customization: add a short wizard-like configuration to the Portlet Selector. Say a user selects a stocks portlet. On an company employee portal, the portlet.xml may default to the stock for that company. Before the portal places the portlet on the page, a generic prefs wizard is presented, allowing the user to set additional preferences (stocks).
Another use case would be from a deployment POV.
I assume you would want to specify preferences on PSML, such as deploying specific preferecnes for a user page or a common (role,group,etc) page. I think this is a good use case.
I know some people have had strong objections to mixing preferences with PSML (layout) in the past. If anyone wants to make an argument against having 'default' preferences in PSML, please make your case.
I think 'default' preferences on PSML seems useful, although it does break the 'separation of layout from preferences' philosophy. I don't think that preferences should be actually stored into PSML from the Portlet API, but I do believe this is a good case for using 'default preferences' per page/user from a deployment POV.

> It should be possible to provide preferences for the initial instantiation of portlets in PSML. These preferences customize the portlet by overriding (or adding to) the default preferences defined in the portlet.xml.
> Example: If I want to have an introductory page displaying e.g. the three most important RSS feeds, then the selection of the RSS stream is related to layout, because I want a layout displaying e.g. "Company news", "Department news" and "Team issues". Binding an RSS portlet to a particular feed makes it a specific item that I want to put at a specific place. I don't want to layout three generic RSS feeds, I want to layout company, department and team news.
> As I want to layout portlet instances, it is not sufficient to be able to layout portlet types. Configuring the instances within PSML would be convenient and intuitive. It would also be acceptable if I could configure the instances in some other configuration file. But only laying out three generic RSS portlets and handing the task to bind the feeds to the end user is not feasable.
