Controlling two remote library instances in one test case

Robot Framework
1

Hello!

We would like to control two Java FX application from the one test case. Below is simplified example from our test case (mytestcase.robot). I can control two UI instances via python code (see MyLib.py) but how the same functionality are done by robot keyword? We have already implemented one “middleware library” on top of JavaFXLibrary using robot keywords, and it is last option to port all this functionality to the python code.

Thanks in advance,
Tarmo

*** Keywords ***
Robot Run Keyword
    [Arguments]    ${libraryName}   ${keyword}  ${keywordParam}
    # How to implement this method in order to get same functionality as in "Python Run Keyword"?
    ${fxLib}=   Get Library Instance    ${libraryName}
    ${fxLib}  Run Keyword     ${keyword}   ${keywordParam}

MyLib.py

from robot.libraries.BuiltIn import BuiltIn
class MyLib:
  def python_run_keyword(self, fxLibraryName, keyword, keywordParams):
      BuiltIn().get_library_instance(fxLibraryName).run_keyword(keyword, keywordParams, None)
