Multi-value column selector problem

[毛进 <da...@163.com>]

Hello, every one :
    I want to fetch the values from a multi-valued column. I used like this :
    xpathQuery.append("//element(*, resource)");
xpathQuery.append("[@type='picture'");
xpathQuery.append(" and jcr:like(@category,'/tpk/mzmjw6115/mjwjdjz6502/m%') ");
xpathQuery.append("]/(@title|@category)");///@category
xpathQuery.append(" order by  @jcr:score descending");

And parse the values:
Value title= row.getValue("title");
System.out.println(title!=null?row.getValue("title").getString():"null");

Value cats = row.getValue("category");
System.out.println(cats!=null?row.getValue("category").getString():"null");


However, i can get the right "title" value. Because it is not multi-valued.
I can not get the correct "category"value, 'cause it is multi-valued.
Why???
And how can i get the multivalued property by using the feature of column selector?
     Thank you all.

Use row.getNode() (since 2.0) to get the node and then normal JCR API
methods, such as node.getProperty("category").getValues() for a
multi-value node.
Or use QueryResult.getNodes() instead of getRows() right away.
