Problem using Filter and NewList with OTA API 12.50

Hello,

I'm currently trying to create a routine where I export some data from the QC to an Excel Sheet, but I need to set some Filter/Filters to retrieve the necessary information in a viable time. ( due the large amount of information in the QC I'm connecting )

Here's a snippet of the code that's giving me trouble:

^{Set testFiltro = testFactory.Filter
    testFiltro.Filter("TS_PATH") = """Root\2015\Release/Speed Line/Pacote/Programa\Pacote P36A%"""
    Set testList = testFactory.NewList}

UFT sends me a error message telling the the "NewList" function is missing arguments. I've already tried to use it like:

^{Set testList = testFactory.NewList("")}

But this way it doesn't follow my Filter rules.

Thanks,
Gabriel Quirino
