creating input part via part descriptor [message #1007776]

Hi there!

In my RCP-Application I have defined a PartDescriptor within a
Perspective and want to place an InputPart there.
Because in PartService there is no method createInputPart(String
descriptorID) I created a utility method using the code from
PartService.createPart(MPartDescriptor descriptor).

public static MInputPart createInputPart(String id, String inputURI,
EPartService partService) {
MPart part = partService.createPart(id);
MInputPart inputPart = MBasicFactory.INSTANCE.createInputPart();
inputPart.setInputURI(inputURI);

inputPart.setElementId(part.getElementId());
inputPart.getMenus().addAll(EcoreUtil.copyAll(part.getMenus()));
if (part.getToolbar() != null) {

inputPart.setToolbar((MToolBar)EcoreUtil.copy((EObject)part.getToolbar()));
}
inputPart.setContributorURI(part.getContributorURI());
inputPart.setCloseable(part.isCloseable());
inputPart.setContributionURI(part.getContributionURI());
inputPart.setLabel(part.getLabel());
inputPart.setIconURI(part.getIconURI());
inputPart.setTooltip(part.getTooltip());
inputPart.getHandlers().addAll(EcoreUtil.copyAll(part.getHandlers()));
inputPart.getTags().addAll(part.getTags());
inputPart.getBindingContexts().addAll(part.getBindingContexts());

return inputPart;
}

Using the returned InputPart I get an InjectionException because there
is no MDirtyable found to inject into my PartContribution class.
Using the part via partService.createPart(id) all works well.

partService.showPart(inputPart, PartState.ACTIVATE); -> Exception
partService.showPart(part, PartState.ACTIVATE); -> everything is fine

I debugged the code and can't find a difference. What am I doing wrong?

Regards,

Jan

MInputPart extends MPart so the MDirtyable sounds strange. It might help
us if you are showing the Exception Stacktrace.

Ok - that looks very strange. Can you please set a breakpoint in
PartRenderingEngine.populateModelInterfaces() and see which context-keys
are pushed there please.

It would be good to have a small standalone sample to debug the problem
and a bugzilla because this looks like a bug to me.

What if you use "@Inject MInputPart dirty" instead of MDirtyable?

Ok, while reimplementing the stuff for a small example I found the
failure: I messed up with the context, overwriting the part context with
a newly created.

Anyway, thanks for help Tom!

Now you know why we always force you to strap down your problem, at
least 50% of the time people find the problem in their code ;-) Good
news for us we don't have a major bug in our system.

I noticed that I was partly wrong. I did not overwrite an existing
context because the part I created has no context.
I investigated this a little further and found that a part gets his own
context when rendered. There is a comment in the PartRenderingEngine
source code that the context should be null before rendering. So when I
create a context to put own information in it, the partrenderer fails to
create the proper context.
This means I can't use the context to deliver information to my part. Or
do I miss something?

Well you can pass on informations through the MPart#properties but those
are only String values. What values do you want to pass?

I want to pass a data object as input for an editor.

Hi,

Well the original idea with InputPart was to one would use something
like an URI and then pass on this URI to a factory get the real input
object - similar to IEditorInput in 3.x.

What are you using the URI for.

If I would have the time to implement it. I'd envision it working
something like this:

MInpuPart p = ....
p.setInputURI("my-protocol://MyObject@[id=1]");

Then would provide a ResourceFactoryService which looks something like this:

interface ResourceFactory {
public <O> O loadResource(String resourceURI) {
// ....
}
}

which can be registered for a protocol e.g. "my-protocol" and finally an
annotation like e.g. @InputResource.

class MyInputView {
@PostConstruct
void init(@InputResource MyObject myObject) {
// ...
}
}

Hi,

the data is loaded from a database and then presented for selection for
further work. This selection can be done in an overview or in a dialog
or something like this. That means the data object exists already at the
time of selection. In 3.x I created my own EditorInput as container for
the data object and passed it to the editor.
In e4 I wanted to avoid implementing the mechanism you described using
the InputURI, because following this way I have to create, pass and
parse an URI to an resource I already have in my hands. That is a little
too much in my thoughts. But in the end it seems the only correct way...

Thanks for help again :)

Well you can naturally push stuff in an upper context e.g. the one of
the perspective or window. The context created is a child of this context.

Would you mind giving me a hint how to register a service for a
protocol, please?
