As recommended while I was trying to figure out, and finally succeeding with
a Simple Drop Down List (hard coded, not from db), I decided to try it
another way, by following the step by step. I created a table in the
database called states:
CREATE TABLE IF NOT EXISTS states (
pkid INT NOT NULL auto_increment,
statename CHAR(40) NOT NULL,
stateabbrev CHAR(2) NOT NULL,
PRIMARY KEY (pkid)
)
Good so far.
Modified the ClientAddForm.cdxml file for the stateprov field:
<dDropdownList code-ID="dDropdownList-dPanel" sizerInfo="{'RowSpan': 1,
'ColSpan': 1, 'HAlign': 'Left', 'ColExpand': True}" rowColPos="(5, 1)"
Choices="[]" designerClass="controlMix" DataSource="clients" RegID="ddState"
DataField="stateprov"></dDropdownList>
Again...good so far.
Now following the step by step for the HoursForm portion I changed the code
for buttons & drop down etc with appropriate changes (deleted the old
ClientAddForm-code.py file) in Class Designer accordingly to populate the
dropdown from the states field so that I end up with a new
ClientAddForm-code.py file as follows:
# -*- coding: utf-8 -*-
### Dabo Class Designer code. You many freely edit the code,
### but do not change the comments containing:
### 'Dabo Code ID: XXXX',
### as these are needed to link the code to the objects.
## *!* ## Dabo Code ID: dButton-dPanel-182
def onHit(self, evt):
self.Form.cancel()
## *!* ## Dabo Code ID: dDropdownList-dPanel
def afterInit(self):
biz = self.Form.getBizobj("client")
names, pks = biz.getStates()
self.Choices = names
self.Keys = pks
self.ValueMode = "Key"
## *!* ## Dabo Code ID: dButton-dPanel-205
def onHit(self, evt):
self.Form.close()
## *!* ## Dabo Code ID: dForm-top
def afterInitAll(self):
self.new()
def afterSave(self):
# This will only get called if the save succeeds
self.new()
self.clientName.setFocus()
def beforeSave(self):
bizobj = self.getBizobj(self.dataSourceParameter)
# If the bizobj hasn't changed, we want to notify the user
# and abort the save process, so that the new record is
# not added afterwards.
if not bizobj.isChanged():
return "No changes have been made; cannot save."
def createBizobjs(self):
conn = self.Application.getConnectionByName("ConsultHours")
bizClient = self.Application.biz.ClientBizobj(conn)
self.addBizobj(bizClient)
## *!* ## Dabo Code ID: dButton-dPanel
def onHit(self, evt):
self.Form.save()
I figured I was good to go. Saved the ClientAddForm file and closed CD. Ran
my main.py file and got the following error:
AttributeError: 'NoneType' object has no attribute 'ClientBizobj'
Here's the full trace back:

What am I doing wrong???
Thanks in advance
