Unhappy nuke.render() can't work!

I made a tool called Make Snapshots which worked pretty well.
And then I wanted to make a panel and put some button and label on it.
But this time I got some problems.The nuke.render() didn't work.
So to find why I made a simply test and here's my simplified script:

 def startMakingSnaps(): 
      wt = nuke.selectedNode()
      nuke.render(wt.name(), 1, 1)
                 
   # create a panel class
   makeSnapsPanel = nukescripts.PythonPanel('Make Snapshots', 'makeSnaps')
   
   # Create knobs
   qtPathKnob = nuke.String_Knob('qtPath', 'QT Path:')
   snapsPathKnob = nuke.String_Knob('snapsPath', 'Snapshots Path:')
   fsOffsetKnob = nuke.String_Knob('fsOffset', 'Frames Offset:')
   makeSnapsKnob = nuke.PyScript_Knob('makeSnaps', 'Make Snapshots')
  
   makeSnapsKnob.setCommand('startMakingSnaps()')
    
   # Add knobs
   makeSnapsPanel.addKnob(qtPathKnob)
   makeSnapsPanel.addKnob(snapsPathKnob)
   makeSnapsPanel.addKnob(fsOffsetKnob)
   makeSnapsPanel.addKnob(makeSnapsKnob)
   
   makeSnapsPanel.show()


Then I got a panel and I clicked the button and a message window poped up to me which said that: Nothing is named "Write1".
But the write node's name is really "Write1".
Then I run this line alone nuke.render(wt.name(), 1, 1) and it worked.


I don't know why.
Is there something different when putting function to the panel?

Pass nuke.render the node object instead of the node name.


 def startMakingSnaps():
	nuke.render(nuke.selectedNode(), 1, 1)
