ClassCastExpception in extended content model

[gressho]

Hello,

I' using the CMIS implementation of Alfresco 3.2 and have defined my own content model extension with some properties which should
occur multiple times:

        <type name="ma:document">
            <title>Dokument</title>
            <parent>cm:folder</parent>
            <properties>
                <property name="ma:docPersonId">
                    <title>Personen-IDs</title>
                    <type>d:text</type>
                    <multiple>true</multiple>
                </property>
                <property name="ma:docOrganisationId">
                    <title>Einrichtungs-IDs</title>
                    <type>d:text</type>
                    <multiple>true</multiple>
                </property>
                <property name="ma:docClassificationId">
                    <title>Klassifikations-IDs</title>
                    <type>d:text</type>
                    <multiple>true</multiple>
                </property>
            </properties>
        </type>
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

When I want to add multiple elements to these extensions with the following code

        CmisPropertyString classificationProperty = new CmisPropertyString();
        classificationProperty.setName(DOCUMENT_CLASSIFICATION_ID);
        for (Classification classification : document.getClassifications()) {
            classificationProperty.getValue().add(classification.getUuid());
        }
‍‍‍‍‍‍‍

I'm ending up in a ClassCastException:

javax.xml.ws.soap.SOAPFaultException: Runtime error. Message: java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String

I couldn't find a Jira task for this and I don't know if my code or assumptions are correct (according to the spec this should be working).

Best wishes

Hi,

I'm using version 3.2r2 and I have the same issue. According to the code CMIS implementation doesn't support multiple properties…
Can you tell us when is going to support it? This is really critical issue.

java.lang.ClassCastException: java.util.ArrayList cannot be cast to java.lang.String
