New null-pointer bug on re-loaded network #35

Open dotasek opened 6 years ago

dotasek commented 6 years ago

Under certain conditions, the Diffusion Output panel starts printing null pointer exceptions to the terminal.

The conditions are a little convoluted, but they're probably pointing to something problematic.

To replicate:

1) Run Cytoscape from a terminal 2) Open a network. 3) Run Diffusion on some nodes. 4) Save network and exit. 5) Reload the saved network. 6) Add a new node and then play around with the Heat Threshold in the Diffusion Output panel.

When I follow these steps, this happens:
