Re: D2W Can I access Object property values from the rule system?
Ramsey hits again!
Thanks a lot. The most obvious is it. Whenever I teach programming (and WO) I
tell my students when it starts to get complicated it most probably is wrong.
Sometimes I do not follow my own advice.
Thanks again

You should be able to do something like
object.documentType.typeString == 'SOMETHING'
Just make sure to terminate your object and session keypaths on an attribute
and not an eo. I'm not aware of any special caching done for EOs in the rule
system, so that would likely result in a big pile of wasted memory.

You should be able to put it in your session (ERXThreadStorage for example) and
access it from there:
pageConfiguration='EditMyEntity' and session.selectedEntity.kind = 'blah' =
displayPropertyKeys =

Great - and then the silly question: How do I put it there? Please some hand

These are methods I use in my Session class:
protected Project _selectedProject;
public Project selectedProject() {
return _selectedProject;
}
public void setSelectedProject(Project selectedProject) {
_selectedProject = selectedProject;
ERXThreadStorage.takeValueForKey(selectedProject(), selectedProject);
}
public void awake() {
super.awake();
// if we have a selected project, keep track of it
if (selectedProject() != null) {
ERXThreadStorage.takeValueForKey(selectedProject(),
selectedProject);
}
}
public void sleep() {
ERXThreadStorage.takeValueForKey(null, selectedProject);
super.sleep();
}
Then when you want to select the Entity you would do something like this (here
I have a custom select component in a ListProject configuration) and I return a
page with the list of activities that are associated with the selected project.
You'll have to figure out where it makes sense for your entity to be selected
in your app.
public WOComponent view() {
Project selectedProject = (Project) object();
((Session)session()).setSelectedProject(selectedProject);
return (WOComponent)
((Session)session()).navController().listActivities();
}
You will find additional examples in BugTracker and SimpleBlog.

David,
Thanks a lot for your input. However my problem lies exactly here (your view()
action). I have a plain auto generated ListPage and the user clicks on the
edit-icon on one of the rows. Would I need a custom property level component
for the edit icon so that I could put some code like yours into or is there an
other (plain D2W) way to accomplish this? How do I intercept the action before
the EditPage is created but after the user has clicked the selected row?
Probably not seeing the forest for the trees anymore. When I am tired I tend to
confuse simple things.

NextPageDelegate allows you to do some customization before returning the
NextPage. Your list page calls this when your Edit button is pressed. I would
do it here if you don't want a custom button.
but after the user has clicked the selected row? Probably not seeing the
forest for the trees anymore. When I am tired I tend to confuse simple things.
In that case you may want to try Ramsey's suggestion before going any further
with mine :-)
