#144 Document Edit - Not used, Missing period, Incomplete period

[Miro Halas]

On the Edit Document Timings tab the are also Not used
period and Missing period controls. But these two
values from document template applies only to
preprinted tracking document and not to actual
document. Therefore these two values should not be on
this screen.

Also the Incomplete period make sense only for document
which is not complete, but you cannot edit incomplete
document therefore the Incomplete period controls
should not be visible on the Edit document screen.

It is also a bug in documentation and the documentation
should be fixed as well. I think we should delete Not
used and
Missing and just hide the Incomplete (leave in the
database and do not show on GUI). I just removed them
from the gui to quickly fix it It have to be of course
removed from object as parameters for Not used and
Missing pariod.
