Am I making it unessesary complex when I use the class? Is there maybe a way to declare the data list global within the module? Or is there another, possibly different, way to do this? Take out all the "import __main__" statements and you should be fine. Python lets you access two namespaces at once: the "local" namespace and the "global" namespace. Were it not for the global namespace, you would need to do something like "import __main__". But since globals are there, everything available at the module level is also available at the function level.

I did what you suggested, but I am still a bit stuck. Maybe I call them
wrong in my code. I use the call below but get an error.
dtml-call expr="createdata('test1','test2','test3')"
dtml-var expr="returndata()"
Error Type: AttributeError
Error Value: data
any suggestions what I do wrong,
I suggest you run Zope in "-D" mode so you can see tracebacks easily.
They can pinpoint the exact source of problems like this.

[Zope-dev] Problem using External Method
The module below works using the python compiler class Testclass: def setdata(self,val1,val2,val3): self.data = [val1,val2,val3] def updatedata(self, index): self.data[index] = self.data[index]+1 def display(self): print self.data x = Testclass() def createdata(): import __main__ __main__.x.setdata(10, 20, 30) __main__.x.updateLog(2) __main__.x.display() createdata() [10,20,31] However if I try to add it as an External Method( id= createdata) it doesn't seem to work. I've tried to call it using dtml-var/call createdata without success. Any suggestions what I do wrong.

Re: [Zope-dev] Problem using External Method
Espen, The files that external methods actually live in are not Python modules, like normal Python modules. Though I haven't tried your example, it's likely that your reference to __main__ is confusing the external method machinery. Additionally, the output of "print" doesn't go to the remote browser, it instead goes to the console. You need to return a value to the caller for it to be displayed on the remote browser. Try instead (as an example): class Testclass: def setdata(self,val1,val2,val3): self.data = [val1,val2,val3] def updatedata(self, index): self.data[index] = self.data[index]+1 def display(self): print self.data def createdata(): x = Testclass() x.setdata(10, 20, 30) x.updatedata(2) return x.display() - Original Message - From: "Espen Sorbye Frederiksen" [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, January 23, 2001 5:52 PM Subject: [Zope-dev] "Problem" using External Method The module below works using the python compiler class Testclass: def setdata(self,val1,val2,val3): self.data = [val1,val2,val3] def updatedata(self, index): self.data[index] = self.data[index]+1 def display(self): print self.data x = Testclass() def createdata(): import __main__ __main__.x.setdata(10, 20, 30) __main__.x.updateLog(2) __main__.x.display() createdata() [10,20,31] However if I try to add it as an External Method( id= createdata) it doesn't seem to work.
