Exception when viewing network

[Albert Cardona]

Hi all,

I created a simple network following examples from the wiki, and using
HierarchicalLayoutAlgorithm, like:

view = Cytoscape.createNetworkView(net, "First net",
HierarchicalLayoutAlgorithm());

The network has about 600 nodes. When trying to visualize it in a
CyNetworkView, it renders fine(it's zoomed in to just a few nodes),
but when zooming out, I get the Exception pasted below.

A smaller network with about 20 nodes doesn't have this problem when zooming.

Also, not using HierarchicalLayoutAlgorithm doesn't have any problem
either. Something is up with
csplugins.layout.algorithms.hierarchicalLayout.HierarchicalLayoutAlgorithm
class.

I am using the jars for cytoscape 2.6.3

What could I be doing wrong? Am I missing something regarding the
application of the HierarchicalLayoutAlgorithm ?

Thanks for any help.

Albert
