ClassCastExpception in extended content model

gressho — Fri, 04 Sep 2009 09:17:11 GMT

Hello,I' using the CMIS implementation of Alfresco 3.2 and have defined my own content model extension with some properties which shouldoccur multiple times: <type name="ma:document"> <title>Dokument</title> <parent>cm:folder</parent>

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
        at org.alfresco.repo.cmis.ws.utils.PropertyUtil.checkProperty(PropertyUtil.java:488)
        at org.alfresco.repo.cmis.ws.utils.PropertyUtil.setProperties(PropertyUtil.java:395)
        at org.alfresco.repo.cmis.ws.DMObjectServicePort.updateProperties(DMObjectServicePort.java:658)‍‍‍‍‍

Thanks.
