Solved: It seems that the problem only occurs with PythonWin. I ran everything through the IDLE's python shell and it worked just fine. Must be a bug with PythonWin and not the code itself. I can't seem to figure out why the following code is giving me a <code>TypeError: 'type' object is not iterable</code> pastebin: <a href="http://pastebin.com/VFZYY4v0" rel="nofollow">http://pastebin.com/VFZYY4v0</a> <pre><code>def genList(self): #recursively generates a sorted list of child node values numList = [] if self.leftChild != 'none': numList.extend(self.leftChild.genList()) #error numList.extend(list((self.Value,))) if self.rightChild != 'none': numList.extend(self.rightChild.genList()) #error return numList </code></pre> code that adds child nodes (works correctly) <pre><code>def addChild(self, child): #add a child node. working if child.Value < self.Value: if self.leftChild == 'none': self.leftChild = child child.parent = self else: self.leftChild.addChild(child) elif child.Value > self.Value: if self.rightChild == 'none': self.rightChild = child child.parent = self else: self.rightChild.addChild(child) </code></pre> Any help would be appreciated.

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
