Yes its possible. However alfresco already has support for multi-valued fields and If you pass in an ArrayList then it will handle that as a collection.

If you really need a list type, look at how alfresco handles MLText values to persist the values to and from database format. And in the extreme case you can persist any serializable java object.

Hi,

Thanks for your reply..

[Yogesh] : If i want to pass any collection object ,in the property of my Aspect what datatype i should pass?

Example :

<aspect name="myaspectname">
         <title>SDXProject</title>
         <properties>
            <property name="mypropertyname">
               <type>d:text</type> [What datatype should i pass here?]
              </property>
</properties>
</aspect>

Something like …

<aspect name="myaspectname">
<title>SDXProject</title>
<properties>
<property name="mypropertyname">
<type>d:text</type>
<multiple>true</multiple>
</property>
</properties>
</aspect>
