java.lang.ClassCastException

I get this error when a multi-value datasource field is empty/null/missing.

java.lang.ClassCastException: java.lang.String cannot be cast to com.google.gwt.core.client.JavaScriptObject
    at com.smartgwt.client.util.JSOHelper.getAttributeAsJavaScriptObject(JSOHelper.java)
    at com.smartgwt.client.util.JSOHelper.getAttributeAsStringArray(JSOHelper.java:310)
    at com.smartgwt.client.core.DataClass.getAttributeAsStringArray(DataClass.java:115)
    at com.logalyze.admin.web.client.data.LogDefinitionDataSource.transformResponse(LogDefinitionDataSource.java:83)

LogDefinitionDataSource.java:83:

String value[] = record.getAttributeAsStringArray("tag");

If 'tags' exist (this is an xml datasource (SOAP)) they look like this:
<record>
<tag>a</tag>
<tag>b</tag>
</record>

The only way I can handle this:

String stringvalue = grid.getSelectedRecord().getAttributeAsString("tag");
if(stringvalue!=null){
	if(stringvalue.indexOf(',')>-1){
		// There are more tags
		String[] tags = grid.getSelectedRecord().getAttributeAsStringArray("tag");
		if(tags!=null){
			//System.out.println("Tags array size:"+tags.length);
			for(String tag : tags){
				... doing something with tag ...
			}
		}
	}else{
		// There is only 1 tag
		... doing something with tag ...
	}
	stringvalue = null;
}

Any idea?
