ClassCastException when trying to create a new plug-in configuration

[Nicklas Nordborg]

If there is a filter on the "Plugin definition" column in the "Plugin configurations" list when the "New" button is clicked in order to create a new configuration a popup window is opened with an error message:

class java.lang.String cannot be cast to class net.sf.basedb.core.Type ...
java.lang.ClassCastException
...at net.sf.basedb.clients.web.Base.getFirstMatching(Base.java:1760)
...at org.apache.jsp.admin.pluginconfigurations.edit_005fconfiguration_jsp._jspService(edit_005fconfiguration_jsp.java:252)
...at org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:70)
...

The error goes away if the filter in the "Plugin definition" column is removed.
