I have a script that gets all of the UIATableCell from a UIATableView. Works great, returns a number of WebdriverElement as expected. Here’s a snippet from the page source.

<UIATableCell name="What&apos;s Happening on the Community in March" label="" value="" dom="" enabled="true" valid="true" visible="true" hint="" path="/0/1/3/1" x="0" y="153.03125" width="375" height="93.75">
                    <UIAStaticText name="What&apos;s Happening on the Community in March" label="What&apos;s Happening on the Community in March" value="What&apos;s Happening on the Community in March" dom="" enabled="true" valid="true" visible="true" hint="" path="/0/1/3/1/0" x="169.921875" y="157.71875" width="163.810546875" height="61.435550689697266">
                    </UIAStaticText>
                    <UIAStaticText name="March 11, 2015" label="March 11, 2015" value="March 11, 2015" dom="" enabled="true" valid="true" visible="true" hint="" path="/0/1/3/1/1" x="169.921875" y="219.828125" width="194.53125" height="24.609375">
                    </UIAStaticText>
                </UIATableCell>

However, my problem occurs when trying to interact with the WedriverElements using code such as:

cells = table.find_elements_by_class_name('UIATableCell')    
for cell in cells:
        name = cell.find_elements_by_class_name("UIAStaticText")[0].get_attribute("name")
        return name

This results in my test code failing with:

AttributeError: 'WebElement' object has no attribute 'find_elements_by_class'

I’ve done this exact same thing in other screens without any issues. Oddly, reviewing the Appium log seems to indicate the element is found, as well as the UIAStaticText children I want.
