[GRASS-dev] g.gui.metadata and wxgui addons in GRASS 7.1

[Blumentrath, Stefan]

Hi,

I just tried to install g.gui.metadata addon with limited success.

No AddOn appears under wxGUI when I run g.extension from the GUI (while e.g. raster addons do show up). Is this probably do to the path in the AddOn repo (which starts with gui and not wxGUI). All other tree elements in g.extension are equal to folder names in the repository...
So, I finally compiled g.gui.extension from source after installing the dependencies.

Now, g.gui.metadata is available, but does not start:

Traceback (most recent call last):

    if self.itemExists(ml[2], varmapset) == False:

    item, cookie = self.GetFirstChild(root)

GetFirstChild
    return _controls_.TreeCtrl_GetFirstChild(*args,
**kwargs)
