attempted pyVCP panel and now Error on startup was created by Beezerlm

I just tried the "This is a LED indicator" example from the pyVCP manual and it seems I broke something.

Created a file called tiny.xml wich contained the following:

<pyvcp>
    <label text="This is a LED indicator"/>
    <led/>
</pyvcp>

Then I ran this command from terminal:

halrun -I loadusr pyvcp -c mypanel tiny.xml

here is the output from terminal:

halcmd: Traceback (most recent call last):
  File "/usr/bin/pyvcp", line 99, in <module>
    main()
  File "/usr/bin/pyvcp", line 87, in main
    pycomp=vcpparse.create_vcp(compname=component_name, master=pyvcp0)
  File "debian/tmp/usr/lib/python2.6/dist-packages/vcpparse.py", line 177, in create_vcp
  File "debian/tmp/usr/lib/python2.6/dist-packages/vcpparse.py", line 47, in read_file
  File "/usr/lib/python2.6/xml/dom/minidom.py", line 1918, in parse
    return expatbuilder.parse(file)
  File "/usr/lib/python2.6/xml/dom/expatbuilder.py", line 922, in parse
    fp = open(file, 'rb')
IOError: [Errno 2] No such file or directory: 'tiny.xml'

And now I get an error when I boot and I don't know where to go from here. Any help would be appreciated. File attached:

*update* - LinuxCNC will start on second attempt. Perhaps the tiny.xml file should be in a different folder? I put it in the ~Emc2/configs/HEALD folder.

Ok. so I added this to the .ini file:

PYVCP = tiny.xml

And the AXIS GUI will load with the led indicator in the top right corner (I didn't hook up hal pins yet)

My questions are: What do the error messages mean? Do you have to run the "halrun -I loadusr pyvcp -c mypanel tiny.xml" command if you are making a panel to run within AXIS?

Just tested it out and it appears you do not need the aforementioned Terminal command for creating a panel within AXIS.

All is good and working as intended. I thought I made a mess of things when I got the error messages, but everything ended up working out fine.
