I am trying to set dc:title property from metadataNode somehow it is throwing exception, I am able to set other properties without any problem

My code is like this

 metadataNode.setProperty("dc:title", "My title" ); // doesn't work throws exception Multivalued property can not be set to a single value (an array of length one is OK): property 

 metadataNode.setProperty("dc:description", " My description"); //works fine no problem  

 originalContentNode.setProperty("jcr:mimeType", "application/pdf");//  throws version exception com.day.cq.dam.core.impl.handler.xmp.NCommXMPHandler Stack Trace: com.adobe.granite.asset.api.AssetException: Unable to create version for asset [ /content/dam/mypdfs/es/MYMail.pdf]:

dc:title property might have defined as multi-valued property. otherwise you can try even  String []title={"My title"}; metadataNode.setProperty("dc:title", title ).

Hope this helps.

Thanks

I already have the following methods but still it is throwing the exception

  private void setMetadata(Node node, String property, String value, ValueFactory vf)
      throws Exception {

    if (node.hasProperty(property)) {
      javax.jcr.Property prop = node.getProperty(property);
      Value propValue = vf.createValue(value);
      if (prop.isMultiple()) {

        List updatedVals = new ArrayList();
        updatedVals.addAll(Arrays.asList(propValue));
        node.setProperty(property, (Value[]) updatedVals.toArray(new Value[updatedVals.size()]),
            prop.getType());
      } else {
        node.setProperty(property, propValue, prop.getType());
      }
    } else {
      node.setProperty(property, value);
    }

 

  }

you can check whether the property a multiple one like this:

final Property property = metadataNode.getProperty("dc:title");
      if (property.isMultiple()) {

metadataNode.setProperty("dc:title", new String[]{"My title"} );

} else {

metadataNode.setProperty("dc:title", "My title" );

}

I tried everything it is updating the property and saving it in CRXDE, but I see the exception in error.log.

Any property starting with dc:  ( dublin core ) standards is throwing this exception, rest of the properties look fine. Program is working fine but internally it is throwing this exception when session.save is called.

Hi

   As far as i coould analyze, i guess you are trying to set a multivalued property to a node. May be u try setting a String variable as

 

String title = "My title" and if you do metadataNode.setProperty("dc:title", title ); 

this issue may get resolved 

 

Thanks
