Error trying to plot multi array in ros2

[mcevoyandy]

When I try to plot a Float64 multi array I get the following error:

[ERROR] [get_message_class]: Malformed message_type: sequence<double>
Traceback (most recent call last):
  File "/opt/ros/dashing/lib/python3.6/site-packages/rqt_plot/plot_widget.py", line 259, in on_topic_edit_textChanged
    plottable, message = is_plottable(self._node, topic_name)
  File "/opt/ros/dashing/lib/python3.6/site-packages/rqt_plot/plot_widget.py", line 154, in is_plottable
    fields, message = get_plot_fields(node, topic_name)
  File "/opt/ros/dashing/lib/python3.6/site-packages/rqt_plot/plot_widget.py", line 137, in get_plot_fields
    for slot, slot_type in field_class.get_fields_and_field_types().items():
AttributeError: 'NoneType' object has no attribute 'get_fields_and_field_types'

I'm using dashing and trying to add the values as topic/data[0]

the echo of the topic is:

layout:
  dim:
  - label: a
    size: 6
    stride: 1
  data_offset: 0
data: [0.0, 0.9924335590913128, 0.22426324056320937, -0.9525528340078406, -0.36382767049387277, 0.9149277755179431]

There is an open PR for this, any updates?

This looks like it was fixed in #71 , so closing this out. Feel free to reopen if I'm mistaken.
