<div dir="ltr">Okay, I've tracked down the issue. It seems as though something changed (either with Java or Jython, hard to say) such that JComponent is no longer imported with `from javax.swing import *`. Now, it is necessary to explicitly do `from javax.swing import JComponent`.<div><br></div><div>I've made that change in Nengo 1.4 master, so the development version listed on <a href="http://nengo.ca/download">http://nengo.ca/download</a> contains this change and should work with Java 8u31.</div><div><br></div><div><span style="font-size:12.8000001907349px">Édi, if you don't want to reinstall Nengo, then you can open up the file `python/space.py` in the nengo directory and add the following line somewhere near the top, with the other import statements:</span><br></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">from javax.swing import JComponent</span><br></div><div><span style="font-size:12.8000001907349px"><br></span></div><div><span style="font-size:12.8000001907349px">Thanks for the bug report!

JComponent, which is what seems to be missing, should be part of javax.swing, which is imported in that `space.py` file. It seems that the recent Java update may have removed JComponent, for some reason, or perhaps Jython is having problems accessing it. In either case, this seems like a problem on our end (or on Java's end) so I'll investigate this immediately and get back to you as soon as I know what's wrong.<br></div><div><br></div><div>In the meantime, if you just want to get things working, you can install an older version of Java (e.g., Java SE 7 at <a href="http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html" target="_blank">http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html</a> )</div><div><br></div><div>- Trevor<br></div></div><div class="gmail_extra"><br><div class="gmail_quote"><div><div class="h5">On Sun, Feb 1, 2015 at 10:15 AM, Édi Kettemann <span dir="ltr"><<a href="mailto:edikettemann@gmail.com" target="_blank">edikettemann@gmail.com</a>></span> wrote:<br></div></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div class="h5"><div dir="ltr">Good afternoon,<div><br></div><div>I'm introducing myself into the Neural Engineering Framework using Nengo framework, to present it to my colleagues from the HPSN at the TU-Dresden ( <a href="http://hpsn.et.tu-dresden.de/index.php?id=4&L=1&type=0" target="_blank">http://hpsn.et.tu-dresden.de/index.php?id=4&L=1&type=0</a> ).</div><div><br></div><div>When I try to call the "Interactive Plots" I get this error message:<div><br></div><div><img src="cid:ii_14b45ada2b8c25ce" alt="Imagem intercalada 1" width="412" height="245"><br></div></div><div><br></div><div>I'm running Nengo on Windows 8.1.
