ImportError: No module named dobject.groupthink

[yell0wfl4sh]

The error is logged on running this activity.

As the dobject directory is a git submodule, please verify that you used git clone --recursive or the Arithmetic bundle file from activities.sugarlabs.org.

We often have problems reported with submodules caused by not cloning recursively. Perhaps we should include the source instead of using a submodule.

@quozl I am facing some difficulties while porting dobject to Gtk+3, I don't know the equivalent of GenericTreeView in Gtk+3, so I am kinda stuck here, please tell me if you know anything about it, thanks.
For more info, see: https://github.com/yashagrawal3/arithmetic/tree/gtk3

@yashagrawal3 does activity run or error is thrown, and an error log would be helpful.

@yashagrawal3 seems your version isn't the same as the one in https://github.com/yashagrawal3/arithmetic/tree/gtk3

[yell0wfl4sh]

sorry, please recheck.

[quozl]

@yashagrawal3, sorry, I don't know anything about GenericTreeView. Check the GTK+ 2 and GTK+ 3 documentation?

GroupThink is in the StopWatch activity too.
