Set enabled after delay not working on Android #6612

Open TylerBoyes opened 5 years ago

TylerBoyes commented 5 years ago

I believe there is a bug on Android versions when using a delay to "fade to" a button and then setting it enabled. Everything works as expected on the iOS build but fails for become enabled on the Android build. I have reproduced this issue with a minimum project and uploaded said project in TestApp.zip.

Steps to Reproduce

To reproduce bug

  1. Setup environment for android development
  2. Build app for Android
  3. Run app
  4. Click button "Show Button"

    Observe "Click Me" fade in

  5. Tap button "Click Me"

    [BUG] Button is not enabled although it has been set so

TestApp.zip

Expected Behavior

Click "Show Button" Button "Click Me" appears and is set enabled When pressing "Click Me" text message should change

Actual Behavior

Click "Show Button" Button "Click Me" is still disabled

Looks like XForms issue. @StephaneDelcroix, could you please take a look at it or reassign to someone in XForms team?

Confirmed the behavior. An easy workaround is to reverse the statements (enable the Button first). Thanks!
