(I know this is an old-ish post, but I came across it when I had another
problem, so thought I'd chime in for the next person to come across it)
It seems like the current solution is to manually add a param to the link with
the param name, and set it to null. This is what the contact example does for
the New Contact link.
| <s:link view="/myPageWithAParam.xhtml" value="Link">
| <f:param name="myParam" value=""/>
| </s:button>
|
This way, seam looks at the link, sees that it has a param already (albeit a
blank one) and carries on its merry way without instantiating an instance of
the object that would provide the param value.
I wonder whether it would be worth a JIRA issue to suggest a flag on the param
tag in pages.xml so the param is only added if the object already exists.
| <param name="myId" value="#{myWidget.id}" required="false"/>
|
In this case, Seam would not create an instance of the widget if it didn't
already exist and it would make the param blank.
If required was true, then it would create an instance and get the Id.
