Problem to create node from palette [message #1824297]

Hi,

You can see my metamodel below (babyidm.jpg) and a screenshot of my .odesign.
My problem is : I don't succeed to create a "Protection" node from the palette, but i can create "Stream" "DataBlock" and "Key". I don't know why. I proceeded the same way as the 3 others.
Could someone tell me where is my mistake ?

Thanks
Léo

The "infos" feature belongs to an "information" object in your model, so I think your tool should be applied on an "information" object and not on the main object.

Thanks for your reply.
Which tool are you talking about ? Section tool ? I don't understand how to apply it somewhere else.

Seems like you first need to change context to the specific "information" element (not just to deatures "infos" which may point to several entities). Since the "protection" node is an element that needs to be contained within a specific "information" node (because of the composition relationship), you first need to navigate to that specifi "information" node (or specify it othewise, and make sure you have created such node befoe the "information" node").

When you select a tool in the palette you then have to click somewhere to apply it, I assume you apply it on the diagram background which would be the "main" object, there is no problem with that but as Avi said the "protection" node is contained by an "information" node, however the "main" object contains many "information" nodes ( or none ), so applying the tool on the "main" object without specifying which "information" node is targeted will not work, so as I said before the proper pattern would be to apply the tool on the "information" node that is targeted to begin with.

Thank you Avi. I understood what you said but do you know how can i navigate to a a specific Information( Stream for exemple) ?
I tried to do something but it's not working (in attachment)

Yes you are right Nicolas, I was applying it to the background, but I can't apply it to a specific information (see the attachment). That's why I think my .odesign isn't good.

yes.
In the create instance properties you can see variable name = instance. You may change it or leave it as it is ("instance").
Then, you need to add another "change context" operation below the "create instance" operation (by right clicking ...). You then use "var: instance" or "aql: instance" for the change context browse expression (in the properties window).

Please let me know you managed it.

Regards,
Avi

P.S. If you wanted to change the context to another entity, and not the newly created one, you may use the "set" operation to declare a variable and then use "change context" operation, or just enter any AQL query for the change context browse expression.

I renamed the variable name of the create instance of NewProtection as "protec". And then I added below a Change Context with "var:protec" (screenshot2.png).
I saved the .odesign but nothing changed on my diagram. I cannot add a protectionNode to a Key, Stream or DataBlock. In fact, it proposes me to create a protection only when I click on the background (main object), and it still doesn't work(4th icon above the cursor on screenshot.png).

Thanks for helping me

Hi,

I can see the problem. If I had the odesign I could have commented better, but I will attempt to suggest some help:
Verify the type that the createProtection tool is applied to (. It needs to be applied to a specific information element (and if not, then you should at least navigate to a specific information element from from the element it is applied to). I do not see it in your tool (Screenshot2).
Specifically, it looks like you are applying the tool a Main element, from there you navigate to a System element (which hopefully was already created, otherwise navigation won't work). Then, from there you navigate to "infos", which is NOT a specific information element. You need to navigate to a specific information instance.

I would suggest that you:
1. try to change the first "change context" to var: container (so that you'll start from the element you clicked on).
2. Assuming the element you clicked on is typed "system" (i.e., the diagram is a representation of system; if it's a representation of another element let me know), create an information element.
3. After the information element creation, in the same tool, change context to the information element you just created and only then create a protection element.
If this works for you, we can continue.

Hi,
here is my .odesign.
I don't know if I was clear at the beginning but my aim is to let the user do these things :

create new keys, streams or datablock
add protection to each one of these nodes (by selecting protection in the palette and clicking on it)

The system node is already created before and yes it's its representation (but I choose a "main" root to see the system node).
I tried to do what you said but I have a problem, I don't know what to write in the reference name of the Create Instance Information, there is no auto-completion when I choose "var:container" in the change context above it.

Thanks

Léo

I don't see the tools in the .odesign file you attached.

Anyway, you seem to be on the way. The first change context is good, provided that the tool is applied to a key, stream or datablock.
The reference name (which you left empty) of the first "create instance" should be "protection" (which is the name of the reference between Information to Protection in your ecore metamodel). Also, the type name should be babyidm::Protection (and not information. The key/stream/datablock element on which the tool is applied inherit "information").
Then, you can remove the second "create instance" (because you already created the element). There is no need for the second "change context" as well, unless you want to make any changes to the protection element you just created (but you can leave it as a provision for).

I did what you said but it still doesn't work (same result as before).
As you can see in the screenshot4 I didn't use the "var:container" for my other create instance so maybe the problem comes from here ? I never succeeded to instantiate object with this var:container (except when I did the StarterTutorial of Sirius).
Thanks

can you share the exact definition of the entire node creation tool and the node representation associated with it?

You can see them in attachments, do you need anything else ?

In the Node Creation Protection, select Advanced tab and try to add all elements (or element you want to have protection: Stream, DataBlock, Key).
I believe this should solve the problem.
Anyway, I am attaching an implementation based on the metamodel you provided. I tested it and it works: click on an existing Stream element after you selected the ""Protection" tool and you will see new protection element on the diagram, and as a component of the selected stream element.

I added my 3 nodes Key/Strem/DataBlock into Extra Mappings in advanced tab of the node creation Protection and it's working !!
The result is exactly what I expected.
Thank you so much for your help !

Hi,
I have a similar problem that I will try to explain usinf this example.
Let's suppose the protection is included in system.. and I want to create a new protection associated to the system by clicking on a key or stream.
In other words, by clicking on the key, a protection associated to the system of the clicked key is created. ( I want to click on a node, but this node is not the container)
I hope It's clear, otherwise I will implement something similar to get a better understanding of the problem.

Thank you
