One pattern I find myself using often is that I have a page listing my
objects (PeopleList) and a detail page (PersonDetail).
In my PeopleList component, I have a WORepetition of WOHyperlink's linking
to specific PersonDetails.
To facilitate the hyperlink, I have an action in PeopleList.java that
creates a new PeopleDetail page and sets the iterated Person in the
WORepetition into a variable on that new page.
My questions:
Is this the right design pattern to use?
If so, is there any way to use ognl or some other mechanism to avoid writing
the action method in PeopleList.java that loads the new page and sets the
Person variable on the new page?
If not, is there any fundamental reason why this cannot be done
automatically (with some syntax modifications/improvements in the WOParser,
or whatever)?
PeopleList.wo:
<ul>
<wo:WORepetition list="people" item="person">
<li><wo:WOHyperlink action="gotoPersonDetail"><wo:string
value="$person.name"/></wo:WOHyperlink></li>
</wo:WORepetition>
</ul>
PeopleList.java
class PeopleList
{
public Person person;
// can this be avoided?
public WOComponent gotoPersonDetail()
{
PersonDetail pd = (PersonDetail)pageWithName(
PersonDetail.class.getSimpleName());
pd.person = person;
return pd;
}
}
PersonDetail.java
class PersonDetail
{
public Person person;
}
