Keyword "Find All Elements" fails (here: Property "ClassName" is "Not Supported")

[JanR-W]

Hello,
in our AUT the UI elements have the property "ClassName" show up as "Not Supported":

Apparently this leads to an error when using the keyword Find All Elements (I'm using the rfdebugger library to debug my keywords interactively inside of my console, but the same error occurs if I use the keyword inside of my test scripts):

> ${edit}= Set Variable /Window/Pane[3]/Window/Pane/Pane/Window[2]/Edit[@Name='user_s']
# ${edit} = "/Window/Pane[3]/Window/Pane/Pane/Window[2]/Edit[@Name='user_s']
> Find All Elements ${edit}
! keyword: Find All Elements ${edit}
! handler execution failed: PropertyNotSupportedException: The requested property 'ClassName [#30012]' is not supported bei FlaUI.Core.FrameworkAutomationElementBase.GetPropertyValue[T](PropertyId property)

Would it be possible to extend Find All Elements with an (optional) argument so that it only tries to read the property of the found elements I actually need and know is supported in my AUT? If not specified it could keep its old behaviour to return all three properties (making it hopefully a non-breaking change to the keyword).

To make it hopefully a bit more clear: I'm thinking of something like this:

Keyword	Arg1	Arg2	Arg3
Find All Elements	<identifier>	msg=None	<property: Either XPATH or AUTOMATION_ID or CLASS_NAME or None, if not specified>

@JanR-W
Thank you for reporting the issue.

This was not considered within the method that properties are not available.

def _find_all_elements(self, xpath: str):
        values = []
        elements = self._get_all_elements_by_xpath(xpath)
        for element in elements:
            values.append(AutomationElement(
                element.AutomationId,
                element.Name,
                element.ClassName,
                FlaUIDebug.GetXPathToElement(element)
            ))

        return values

Since these are accessed in the Find_All_Elements method and should be saved as a list, there is probably an exception within the execution on this element.

This is a bug that we will fix.

We could solve this with an argument that can be selected and also that there is simply an empty string.

That was a very quick fix, thank you so much!

EDIT: I can also confirm that Find All Elements for me now works as intended 👍
