I noticed that sometimes RSS feeds do not have values for all their
attributes, even in the title and the link nodes.
When this occurs, it causes a stack trace in RSSPortlet getItems. The
problem is that the handling of the title and link nodes needs to be coded
the same way the description node is written, with a "not null" check
before gettting the node value. It should look like this:
private Item[] getItems( NodeList items ) {
....
for ( int j = 0; j < itemChildren.getLength(); ++j ) {
Node child = itemChildren.item( j );
if ( child.getNodeName().equals( "title" ) ) {
+ if (child.getFirstChild() != null) {
title = child.getFirstChild().getNodeValue();
}
if ( child.getNodeName().equals( "link" ) ) {
+ if (child.getFirstChild() != null) {
link = child.getFirstChild().getNodeValue();
}
if ( child.getNodeName().equals( "description" ) ) {
if (child.getFirstChild() != null) {
description = child.getFirstChild().getNodeValue();
}
}
}
....
}
