ClassCastException in Experiment overview when clicking on an experimental factor

[Nicklas Nordborg]

1. Select an experiment which has at least one experimental factor. There doesn't have to be any data.
2. Go to Experiment overview
3. Click on the tree and select one of the experimental factors of the experiment.
4. An error happens in the upper right frame. Here is the stack trace:

net.sf.basedb.core.Experiment cannot be cast to net.sf.basedb.core.Annotatable
java.lang.ClassCastException
...at org.apache.jsp.views.experiments.overview.info_jsp._jspService(info_jsp.java:491)
...at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)

And lines 485 - 493 from info_jsp.java:

485   if (node.getName().startsWith("parameter"))
486   {
487      annotatable = (Annotatable)node.getParent().getParent().getParent().getItem();
488   }
489   else
490   {
491      annotatable = (Annotatable)node.getParent().getParent().getItem();
492   }
493   dc.reattachItem((BasicItem)annotatable);
