4.2RC3 : datatype with properties :: cannot assign property value in 'Properties'-View [message #888751]

Hello everyone,

I am quite new to papyrus and need some advice from you experts:

My goal is to model databases using a class diagram and applying a codegenerator for generating ddl-code using the juno-release

== progress so far ==

* setup metamodel by creating a new profile

create Stereotype <BusinessEntity> extends metamodel class
custom datatype: varchar, number, date (plain, no connections to some metamodel)

each custum datatype has some properties like fraction digit and so on

* apply metamodel
created papyrus-project and attached metamodel

Question 1:

when perform the action 'Model Explorer' [context-menu:import->import registered profile] my profile does not appear. How can i add my metamodel in this list ?

I apply my steretype by selecting my model -> Properties -> Profile -> Apply Profiles, this works just fine.

I've created a new class-diagramm and can apply my stereotype to the classes and can add properties to them like 'salary' with the datatype 'number'.

My problem is now that i cannot edit the custom properties in the 'Properties'-View in papyrus when selecting the property 'salary'. I want to set the fraction digits for that.

Can one please give me a hint how to do this ? If one help me i will write a tutorial. All the documentary i have found is stereotype-specific

Thank you
Martin

You have to create a plug-in, and use the "org.eclipse.papyrus.extensionpoints.uml2.UMLProfile" extension point to register your profile. However, this is not required, as you can still use the "Apply profile" (From local workspace) button from the Profile tab of the properties view.

Datatypes properties are currently considered as String properties. Can't you edit them at all ? It seems to work fine for me.

Profile tab > Unfold your stereotype > Select the property 'salary' > Use the Text box on the right to edit the value (As a String)

Camille

Hello Camille,

thank your for your quick reply. I know that stereotypes have string-properties to edit but my datatype have no stereotype at all.

I've added a screenshot for better understanding. May you have a look at it ? (sorry for bad resolution). Maybe i need to define 'subsetted property' to adress the nested properties of my datatype 'Number' ?

Again: My usecase is to model a class as representing a database table. One property represents a column. I need to specify the colum (name, comment, fraction, type and so on) and want to store this information in the uml-model. The right place for me seems to be some nested properties defined in the datatype number, varchar and so on.

greetings
Martin.

Hello,

What I actually meant is that the Datatypes structure is lost when you apply the stereotype. The properties typed by a structured datatype are actually considered as String properties.

Hello Camille,

good to see that this issue is already being adressed.

I am a beginner in papyrus and still learning. As far as i understand this problem have nothing to do with stereotypes. I've created an other sample using just one class and a datatype defined in the same model. I still can't easily set values from that datatype using the property-view. (see screenshot er_diagramm.JPG, good quality this time Very Happy

)

However i will have a look if i can cover my usecase with subproperties.

thank you for your help.

mercy
martin.

Martin,

what you want to achieve is semantically not correct. You want to set the
value of a property at type level. Please be aware that concrete values are
not set at type level (well, defalt values can be set anyway for a
property), but at instance (specification) level. So you would have to
create an InstanceSpecification (e.g. for Number) with slots representing
concrete value (specifications) for a particular property.

What you've tried in your latest post (property subsetting) is semantically
wrong.

you are right i had mixed up something.

I've definded a stereotype 'EntityAttribute' that has nested properties like 'comment' and so on. These can i use to specify my attributes in more detail and can edit as well.

Thank you for pointing me in the right direction.

Martin.
