I would define your aspect as an independent aspect in your own model.

Then, I would use rules to:

- specialise the type (to the sub-type of content you've defined)
- add your custom aspect
- add the versionable aspect

Hi David,

thanks for your reply.

I would define your aspect as an independent aspect in your own model.

Do you mean that I should not use a new content type but only a new aspect ?
Or Do I need to create a new content type with no properties and only defined the properties within the new aspect ?

(I am sorry, I am not yet very familiar with Aspect and Content Type)

Then, I would use rules to:

- specialise the type (to the sub-type of content you've defined)
- add your custom aspect
- add the versionable aspect

I think I got this point 🙂
Just need to know if I also need a custom content type + a custom aspect … or only a custom aspect …

Best regards,

Sylvain

It seems you only require a custom aspect.

Ok thanks,

In order to create a custom aspect to my document,
I think I just have to do the same than creating a content-type (using the custom-model-context.xml + customModel.xml) …

That's correct.

That's correct.

this is working perfectly …
but now, I've got a new requirement 🙂

I though I could implement them easily but I am not sure after few unsuccessfull test :

specifying 2 aspects with the same properties but:
- in aspect 1, some properties are not mandatory
- in aspect 2, they are mandatory
- when a document is moved from one workspace to the other one, aspect 2 is applied and then properties set in aspect 1 are copied ?

is it something possible ?

Execute a javascript action via rule.

With javascript you can copy property values.

Thanks again …
is it possible to specify the 2 aspects like that (in a different way) :
     <aspect name="ns:asp1">
        <title>aspect 1</title>
        <properties>
            <property name="ns:attr1">
                <type>d:text</type>
                <mandatory>true</mandatory>
            </property>
            <property name="ns:attr2">
                <type>d:text</type>
                <mandatory>false</mandatory>
            </property>
        </properties>
      </aspect>

      <aspect name="ns:asp2">
              <title>aspect 2</title>
              <properties>
                 <property name="ns:attr1">
                   <type>d:text</type>
                   <mandatory>true</mandatory>
                  </property>
                  <property name="ns:attr2">
                      <type>d:text</type>
                      <mandatory>true</mandatory>
              </property>
              </properties>
       </aspect>

or should I specify different property names (for now it is failing compiling the model because the attribute name is already used in ns:asp1)

Property names must be unique within a model.

Thanks a lot !
I am moving fast with your help 🙂

I have a latest question for this Aspect stuff :

regarding my 2 aspects (asp1 and asp2), when I move the document from one workspace to the second one, the second workspace has the following rules applied :
- call a script :
- add aspect asp2 to the document if it has aspect asp1
- copy the properties from asp1 to asp2
- remove aspect asp1 from the document (I do not find the script method for that)

Now, if the attr2 was empty in asp1, it is empty in asp2.
It is not a problem has other user will have to review the document before performing new action.
But I need now to ensure that this attribute will be set before the next Simple Workflow could start … How can we do this ?

I though to create a script which would be call before the start of a Simple Workflow, but the simple workflow cannot run a script … just move a document to another place …
