Dynamic UI Element Selectors with PowerFX Enabled?

Posted on 4 Apr 2024 15:44:38 by 43

Apologies in advance if this isn't appropriate content for the forum...I'm not seeking technical advice for a specific flow. Rather, I'm wondering if anyone has had luck trying to do something that I was unable to make work. Have any of you built a desktop flow, with PowerFX enabled, that used browser automation actions using dynamic UI element selectors, i.e. selectors in which a flow variable is incorporated into the selector text?

    D'oh! I just realized the red notations were part of your screenshots and not the picker itself. Not my proudest moment.
    Thanks once again for your help, as always.

    I understand your concern. Just to clarify, Power Fx enabled flows do not support dynamic selectors.

    This limitation is also mentioned on the Microsoft website, as shown in the screenshot below (highlighted in yellow).

    Dynamic selectors are only supported for workflows that are not enabled with Power Fx.

    Re: Dynamic UI Element Selectors with PowerFX Enabled?

    Thank you very much. Seeing that red warning at the top of the Selectors window would have saved me a lot of time. However, it does not appear in my Power Automate Desktop environment when I go to edit GUI selectors in a PowerFX enabled flow:

    Any idea why it doesn't appear? Is there a setting I can change somewhere?

    Dynamic selectors are not supported in Power FX-enabled flows. Please refer to the screenshot below.

    The variable picker is not available in Power FX-enabled flows, unlike what we see in Power FX-disabled flows.
