[kepler-dev] kepler/ptolemy problem

[Dan Higgins]

Hi All,

I have run into a problem with the attached workflow (test.xml). The 
graphical representation is shown below.

The model is fairly simple. The ramp iterates from 0 through 4 and the 
first time (0) the switch should output a token which causes "Testing" 
to be written to the output file. When the ramp output is not 0, no 
token should be sent to the T output and nothing should be output.

This model runs just fine with Kepler using PTII5.0-beta as its base. 
However, it does NOT run when I use the head of Ptolemy CVS! (This would 
seem to indicate that some recent change in Ptolemy is the problem, 
since I am using identical Kepler code int the 2 cases.)

The error message is "Queue is at capacity of 1" and this occurs when 
the ramp output is 1 (i.e. it works OK for a ramp output of 0)

Any ideas from anyone on what the problem is?



The stack trace is:
