Since AVM doesn't like you to have other object types other than wcm:avmplaincontent (I believe this is true in alfresco 3.0b and c), we added properties and aspects directly into the wcmModel.xml (it's in tomcat\webapps\alfresco\WEB-INF\classes\alfresco\model)

So our avmplaincontent looks something like


        <type name="wcm:avmplaincontent">
            <title>AVM Plain content</title>
            <parent>wcm:avmcontent</parent>

            <properties>
                <property name="wcm:dateAuthored">
                    <type>d:date</type>
                </property>
                <property name="wcm:filename">
                    <type>d:text</type>
                </property>
                <property name="wcm:type">
                    <type>d:text</type>
                </property>
                <property name="wcm:locale">
                    <type>d:text</type>
                    <index enabled="true">
                        <atomic>true</atomic>
                        <stored>false</stored>
                        <tokenised>false</tokenised>
                    </index>
                </property>
            </properties>


            <mandatory-aspects>
                <aspect>wcm:virtualURL</aspect>
            </mandatory-aspects>

        </type>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Hopefully this will help

When you have added the custom attributes, does the change reflect to the whole alfresco in the system (or) can we limit the custom attributes scope only to a particular webproject

It's to the whole environment. Although it might only apply to new objects, this I'm not sure about.

If you want to have certain attributes to certain situations, you can use aspects!


        <aspect name="wcm:displayable">
            <properties>
                <property name="wcm:showInLeftNav">
                    <type>d:boolean</type>
                </property>
                <property name="wcm:showOnSiteMap">
                    <type>d:boolean</type>
                </property>

            </properties>
        </aspect>‍‍‍‍‍‍‍‍‍‍‍‍

Attaching the aspect above to a particular object would enable the object to use the properties wcm:showInLeftNav and wcm:showOnSiteMap

Hopefully it helps

Thanx for the reply Jack.

Here, when I am creating new custom attributes for a document, the new attributes are getting reflected everywhere except the webproject. In the webProject, when Iam creating a new content, it is not asking to fill any of the custom attributes. But, if the create a new content in any space otherthan webproject, the custom attributes are getting displayed. But whynot in webProject???

No problem!

I hope I'm understanding you correctly - you can't edit the properties after adding the aspect to a piece of content.

I have always added aspects in webscripts, and used the properties in aspect in webscripts. I'm not sure how do you bring it up to Alfresco front end… My guess would be one of the files in alfresco/tomcat/webapps/alfresco/WEB-INF/classes/alfresco.

Anyone else happen to know how to expose additional properties to the front end?
