I'm automating a process that starts on a website and when I click a link it opens a Java iframe on the desktop. This is the window that opens:

I can interact with the interface by getting the data from the text fields, clicking buttons, etc. But I can't get the text of the selected item in a combobox.

If I try to extract the Name attribute from the combobox, I can extract it, but if I want to extract the Own text I get the following error:

Object reference not set to an instance of an object.: Microsoft.Flow.RPA.Desktop.Modules.SDK.Extended.Exceptions.InternalActionException: Error in extraction (could not be extracted) System.NullReferenceException: Object reference not set to an instance of an object.

What should I do?

It's very strange, I can do any action on the element, like click, select item from list and get attribute data and it lets me get any attribute except text :S

Failed extract the text of the selected item in a combobox from a java application

Hi @CFernandes!

I had already read that link and as for limitations in combobox it is only limited to click activities in simulation mode, but I do not see any limitation in the Get details of a UI element in window activity.

As I said, the element recognizes it since I can select an option from the combobox or obtain its name attribute. What I cannot do is get the Own text since it gives me the error I mentioned (Object reference not set to an instance of an object).

When you tell me to get the data from the source, it is not a solution for me since it is a third-party application and I do not have access to the direct query to the database.

Out of curiosity I have tried with another RPA (uipath) and the text can be obtained without difficulty, so I understand that the element has no restrictions in terms of obtaining the text from the combobox.

There should be some way to get the text. What am I missing?

Hey @CU09081859-0

I have seem this error in the past and there are limitation on https://learn.microsoft.com/en-us/power-automate/desktop-flows/actions-reference/uiautomation#known-limitations-for-performing-an-action-by-simulation

See if you are hitting one? You might want to query the Data-Source(SQL, etc) and then fetch the data directly from DataSource. That should be an easier solution.
