When trying to view documentation the second time, there is some error
information on the console: 

Error in getting actor in ShowDocumentationAction
Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
    at
ptolemy.vergil.basic.GetDocumentationAction.showDocumentation(GetDocumentationAction.java:140)


If I try to drag an actor on the canvas after that, I get an error dialog: 

Change failed
Cannot create entity without a class name. in [external stream] at line 2 and
column 25

There are additional console errors: 

Error inside GetMomlFromLSID.getMoml(): empty error message
Error creating alternateGetMoml!
Change failed: <group><group name="auto">
<entity name="SelectionDialog">
<property name="_location" class="ptolemy.kernel.util.Location" value="{155,
245}"/>
</entity>
</group>
</group>
