Hello
I'm trying to use PyDev 1.4.2 with Jython 2.2.1. I can launch a debug session,
and stop on break points. The problem is that I can't see any variables. Instead
I get a pydev ERROR - Could not resolve variable.
The error log showed the issue to be the line arrowed below in pydevd_comm.py:
class InternalGetVariable(InternalThreadCommand):
""" gets the value of a variable """
def __init__(self, seq, thread_id, frame_id, scope, attrs):
self.sequence = seq
self.thread_id = thread_id
self.frame_id = frame_id
self.scope = scope
self.attributes = attrs
def doIt(self, dbg):
""" Converts request into python variable """
try:
xml = "<xml>"
valDict = pydevd_vars.resolveCompoundVariable(self.thread_id,
self.frame_id, self.scope, self.attributes)
#>>>>>>>> keys = sorted(valDict.keys())
keys = valDict.keys()
for k in keys:
xml += pydevd_vars.varToXML(valDict[k], str(k))
xml += "</xml>"
cmd = dbg.cmdFactory.makeGetVariableMessage(self.sequence, xml)
dbg.writer.addCommand(cmd)
except Exception:
cmd = dbg.cmdFactory.makeErrorMessage(self.sequence, "Error
resolving
variables " + GetExceptionTracebackStr())
dbg.writer.addCommand(cmd)
I commented out the line. Now I can see top level globals, however I still have
the same issue for other variables and if I drill inside globals. The error
log tells an unhappy story:

Could you give me some pointers to sort this out? Is this configuration
correct/supported? Anyone else have/had this issue?
Cheers, Ben
