[kepler-dev] Can "stop" interrupt "initialize()"

[Laura L. Downey]

Just a note -- type checking is a menu item in the tools menu design for the
future.  And we have some different options to decide on about whether type
checking should be automatic or user initiated etc.  I believe the last
discussion on this we decided that workflows could run with semantic
mismatches but would not run if there were structural mismatches.

No problem ... I thought you were referring to structural types -- int,
string, array of double, etc.  I agree with Bertram that structural type
checking would be very useful to have has a button akin to a staging
button, a run button, a stop button, and so on.  The semantic type stuff
is not essential to running a workflow --
