overriding properties simply does not work

[sbixsbix]

Hi,
I have opened several threads because I was trying to override the cm:description property.
Then I decided to leave description as it is and to override some properties of my content not inherited by cm:content.
This is the relevant portion of contentmodel.xml file:
        <type name="acme:acmeCommon">
           <title> Modello base CM acme</title>
           <parent>cm:content</parent>
           <properties>
                 <property name="acme:XXX1">

                   <mandatory>false</mandatory>
                </property>
                <property name="acme:FilingDate">

But when I stop & start Alfresco I got always the same error:

Are there someone who can say which is the correct syntax for overriding properties?

[mitpatoliya]

That is because your model is not defined properly.You are not following the schema properly.
Constrains should be defined out side the type tag
Refer the out of box content model file for proper syntex and schema.

Mits,
I tried also to put the constraints out of the <type name="acme:blah"> blah blah </type> block, but it still does not work.
This is the complete model with thew constraints taken out:

I tried also to throw away all the constraints overrides.
No, overrides for constraints, only for the title of the properties of my own model, properties not inherited by the cm:content.
NO WAY, same error

[mitpatoliya]

Please post your modified content model.
also you need to validate the model xml file from eclipse or whatever IDE you are using.
If there are any problem with tags you will come to know.

[sbixsbix]

Mits,
I have already posted the whole xml file by cut&paste in the post of 04/04/2013 - 08:14.

Probably it is possible to change only some values nothing more

[mitpatoliya]

still getting the same error even after removing the constrains?
And which kind of limitation you meant here?

[sbixsbix]

Mits,
forgive me for the delay in aswering.
Yes, still getting same error, even after removing constraints.
After some thoughts about I have to conclude that some changes on cm:whatever are obviously forbidden.
Try to imagine what should happen if I could change the type of cm:description in, lets say,  d:float.

[ipirat]

Absolutely. According to modelSchema.xsd:

   <xs:complexType name="propertyOverride">
      <xs:sequence>
         <xs:element name="mandatory" type="xs:boolean"
            maxOccurs="1" minOccurs="0" />
         <xs:element name="default" type="xs:string"
            maxOccurs="1" minOccurs="0" />
         <xs:element name="constraints" maxOccurs="1"
            minOccurs="0">
            <xs:complexType>
               <xs:sequence>
                  <xs:element name="constraint" type="dd:constraint"
                     maxOccurs="unbounded" minOccurs="1" />
               </xs:sequence>
            </xs:complexType>
         </xs:element>
      </xs:sequence>
      <xs:attributeGroup ref="dd:name" />
   </xs:complexType>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

the override only will allow overriding "mandatory", "default" and "constraints".


As for the Business Case: It's still the same Property after all. Depending on a (specialized) type or aspect, the property may become mandatory or more/less restrictive with the constraints.

Example: foo:doc has a prop "fooublishingDate". an aspect fooublished will make the "fooublishingDate" mandatory and may add a constraint, that the publishingDate must be in the past.
