Error while opening a xml file in visualstates. #134

Closed pankhurivanjani closed 5 years ago

pankhurivanjani commented 5 years ago

While working on Visualstates with ROS2, I got the error of

IndexError: list index out of range

When I checked it with ROS1, I am getting same error here too, I didn't change anything in the code for ROS1. I am using ROS Melodic with Ubuntu 18.04.

This error is coming when I try to open .xml file in Visualstates GUI.

Exact error is:

Gtk-Message: 12:05:57.318: GtkDialog mapped without a transient parent. This is discouraged.
Traceback (most recent call last):

    (rootState, config, libraries, globalNamespace) = self.fileManager.open(fileName)

@sudo-panda @pushkalkatara @okanasik Could you please suggest something for it?

Can you send the XML too?

Here, it is https://github.com/JdeRobot/base/tree/master/src/examples/visualStates/ros/obstacleAvoidancePython

Instead of examples given in jderobot base repository, I used examples from visualstates-example repository and it worked fine.
