Not able to create the Project Documentation
Symptoms
Project documentation cannot be created in Desktop for Eclipse / Developer Edition.
Error messages tell the user that a project needs to be open to create the project documentation - although the creation is started from within a project.
Resolution
The issue is not with Desktop for Eclipse itself, but rather that in Eclipse there is not target to which the resulting PDF could be saved.
It is needed to create a normal Eclipse project (i.e. file area in Eclipse's Navigator), then creating PDFs should work fine as Eclipse can then store the file in the default project.
If Desktop for Eclipse and Eclipse are installed together with the VoiceObjects installer, Eclipse already has a default project.
