Run Keyword In Separate Thread keyword not found even though it's in the script - robotframework-swinglibrary

Question

I have a robot script with the following keywords:
Enter New Data Group
SelectDialog New Data Group
Button Should Be Disabled okButton
Type Into Text Field nameTextField EnteredByRF1
Type Into Text Field descriptionTextArea EnteredByRF1
Button Should Be Enabled okButton
Push Button okButton
Run Keyword In Separate Thread Check OverWrite
Check OverWrite
SelectDialog New Data Group
Push Button OK
SelectDialog New Data Group
Push Button Yes
When I run the script, it gets to the Run Keyword in Separate Thread and produces a Keyword Not found error. I understand from the docs that to handle a popup that may or may not appear, it needs to go in a separate thread.
If I run it without the Separate Thread keyword, it works fine, IF the popup appears. No popup, it fails.
How are you supposed to use this keyword? Is it the right solution for this test scenario?

Answer 1

After some experimentation, it appears Run Keyword In Separate Thread only works for pre-defined keywords in the SwingLibrary package.
By changing the sequence to:
Run Keyword In Separate Thread SelectDialog New Data Group
Run Keyword In Separate Thread Push Button OK
Run Keyword In Separate Thread SelectDialog New Data Group
Run Keyword In Separate Thread Push Button Yes
The RF script now works as expected.
