Hello,
I'm implementing a Workflow Editor using EMF to design the model and GMF
to implement the visualization. I have two attribute in the same EClass
that are required to show a drop down list retrieved from a server. The
element A retrieves the list using the getChoiceOfValues methods, and it's
working. The element B needs to retrieve the drop down list dynamically,
according to the value selected by the user for the element A.
I know that to use notification, I have to change something in the
notifyChange method, but I don't know exactly how. Moreover using GFM, I
don't know if implementing the notification in EMF, this will be working
also in GMF.
Sorry for the silly question, but I spend a day, I'm still confused. Is
there any tutorial or example that explains how to realize a notification?
Cheers
Nicola

Nicola,
All changes to the model will produce notification, though only if
there's something listening, i.e., if eAdapters() isn't empty. The
notifyChanged method in the item provider is only acting as a filter and
a router, i.e., it's decides which notifications are interesting and
decides how they will be forwarded to the factory, which in turn uses
that information to update the view. I'm not sure how this is involved
in the problem you describe? Don't you fetch the choices of values each
time the method is called? Or are you caching them and needing to
decide when to refetch them? For that purpose, you might just cache the
value used the fetch last time and if you need to fetch and that value
doesn't match you fetch based on the new value, i.e., do it on demand
rather than as a result of responding to a notification.

Hello Ed,
sorry for bugging you again, but I'm still confused. What I want to do is
really simple, I just don't know how to do it. Actually I haven't any
Adapter in my code, thus I suppose I'm doing something really wrong. Is
there any example (or a tutorial) that implements some kind of
notification?
Thanks in advance for the time you are spending helping me.
Cheers
Nicola

It's almost a contradiction. :-P

I wonder what it is your doing. You didn't actually answer any of the
questions I asked.

Every generated editor shows notification in action. For example, use
the properties view to change the property used as the label in the tree
view for some object and set a breakpoint in the notifiyChanged method
of the item provider for that type of object. When you change the
property, the tree view updates because of the notification that you
breakpoint will hit.

Hello Ed,
I'm back, again... I didn't answer to any of your question, just because I
didn't know how to answer:). Now my ideas are (just a bit) more clear. I'd
like fetch B values every time A changes. I don't think I need to cache
the values.
I managed to obtain a working editor that every time A change stores the
new value in a String. I'm not sure this is the correct way of working,
but I'll post the code just in case it might be useful for somebody
looking for a similar solution.
public class BaseResourceActivityItemProvider ...{
private String selectedResource = "";
protected Adapter resourceActivityAdapter = new AdapterImpl(){
public void notifyChanged(Notification notification){
if (notification.getFeatureID(BaseResourceActivity.class) ==
ModelPackage.BASE_RESOURCE_ACTIVITY__RESOURCE) {
selectedResource = notification.getNewStringValue();
}
}
};
.
.
.
protected void addInstanceNamePropertyDescriptor(Object object) {
itemPropertyDescriptors.add
(new temPropertyDescriptor
(((ComposeableAdapterFactory)adapterFactory).getRootAdapterF actory(),
getResourceLocator(),
getString("_UI_BaseResourceActivity_instanceName_feature"),
getString("_UI_PropertyDescriptor_description",
"_UI_BaseResourceActivity_instanceName_feature",
"_UI_BaseResourceActivity_type"),
ModelPackage.Literals.BASE_RESOURCE_ACTIVITY__INSTANCE_NAME, true,false,true,
ItemPropertyDescriptor.GENERIC_VALUE_IMAGE,null,null)
{
public Collection getChoiceOfValues(Object object){
Collection activities = new ArrayList(); if(selectedResource=="")
//I need to fetch a default list if no resource is selected
activities.add("Test");
else{
//fetch the activities according to the selected
resource
}
return activities;
}
});
}
protected void addResourcePropertyDescriptor(Object object) {
//similar to the above mothod
..
..
public Collection getChoiceOfValues(Object object){
//fetch the resources
return resources;
}
}
..
..
public String getText(Object object) {
((BaseResourceActivity)object).eAdapters().add(resourceActiv ityAdapter);
String label = ((BaseResourceActivity)object).getName();
return label == null || label.length() == 0 ?
getString("_UI_BaseResourceActivity_type") :
getString("_UI_BaseResourceActivity_type") + " " + label;
}
}
I'm not perfectly sure about this code, but at least is working with the
EMF editor. Now I have to implement the same solution with the GMF editor,
I'm trying to modify the handleNotificationEvent() method in the edit.part
using
SetCommand sCommand = (SetCommand)
SetCommand.create(editingDomain,feature, attr, "pippo");
but right now is not working.
Cheers
Nicola

I suppose I wonder why you need them immediately after A changes rather
then fetch them on demand when they are needed.

Why base this on a cached value rather than using object to navigate to
the A instance that will yield the information?

It's not clear what's not working. Is the right adapter attached? Can
you change the design to not use a cached value but rather determine the
selected resource from the "object" argument?

Thank you very much!
I haven't thought about using directly the "object" argument! Now it's
working.
