JS runtime exception during resize of invariants tab #213

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
When the invariants tab is resized, the following exception is raised 
non-deterministically. The issue is that a boolean value is returned when a 
float is expected. I think the problem is that the Raphael path object is not 
initialized when it is queried for its BBox field.

com.google.gwt.dev.shell.HostedModeException: Something other than a float was 
returned from JSNI method '@synopticgwt.client.invariants.Path::getBBoxY()': JS 
value of type boolean, expected float
