Alfresco: Found 1 integrity violations: The association source type is incorrect

Question

I want to create vncr:sender node as a child node of nvcr:senders node (custom types).

vncr:senders model :

    <type name="vncr:senders">
        <title>Courrier senders</title>
        <parent>cm:content</parent>
        <associations>
            <child-association name="vncr:contains_sender">
                <source>
                    <mandatory>false</mandatory>
                    <many>false</many>
                </source>
                <target>
                    <class>vncr:sender</class>
                    <mandatory>false</mandatory>
                    <many>true</many>
                </target>
                <duplicate>false</duplicate>
            </child-association>
        </associations>
    </type>

vncr:sender model

    <type name="vncr:sender">
        <title>Courrier sender</title>
        <parent>cm:content</parent>
        <properties>
            <property name="vncr:name_sender">
                <type>d:text</type>
                <mandatory>true</mandatory>
                <multiple>false</multiple>
            </property>
            <property name="vncr:email_sender">
                <type>d:text</type>
                <mandatory>true</mandatory>
            </property>
        </properties>
    </type>

Template instance component

    <component>
        <region-id>sender</region-id>
        <url>/components/form?mimeType={mimeType}</url>
        <properties>

            <itemId>vncr:sender</itemId>
            <destination>{destination}</destination>
            <mode>create</mode>
            <submitType>json</submitType>
            <showCaption>true</showCaption>
            <showCancelButton>true</showCancelButton>
            <htmlid>{htmlid}</htmlid>
        </properties>
    </component>

Answer 1

You are trying to create a "cm:content" under a "cm:content", I do not think that is possible. Error message tries to convey this too, by saying that it expects "cm:folder".

Note, you can associate two cm:content nodes, just not with parent/child association.
