Bug 288477 – [WPE] Mouseklick not working anymore with 2.46.x using ENABLE_WPE_PLATFORM

• Status: RESOLVED
• Resolution: INVALID
• Component: WPE WebKit

Hello,

we're using a snap based on https://snapcraft.io/wpe-webkit-mir-kiosk, and updated to webkit 2.46.x (https://wpewebkit.org/release/)
Since wpewebkit2.44.x the mouse click event does not work anymore. I found some changes mentioned in

https://github.com/WebPlatformForEmbedded/WPEWebKit/blob/wpe-2.46/Source/WebKit/wpe/NEWS:

"Add a ENABLE_WPE_PLATFORM build option to CMake. This is disabled by
default because the WPEPlatform API is in development and provided as
part of the 2.46.x releases as a preview feature."

Because I'm not sure if the feature is temporarily not available or has to be enabled explicitly with some options, please let me know how to get this working again. We appreciate any help.

https://github.com/WebKit/WebKit/blob/main/Source/cmake/OptionsWPE.cmake:

if (ENABLE_WEBDRIVER)
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_KEYBOARD_INTERACTIONS ON)
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_MOUSE_INTERACTIONS ON)
if (ENABLE_WPE_PLATFORM)
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_TOUCH_INTERACTIONS ON)
else ()
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_TOUCH_INTERACTIONS OFF)
endif ()
SET_AND_EXPOSE_TO_BUILD(ENABLE_WEBDRIVER_WHEEL_INTERACTIONS ON)
endif ()

What do you mean by "Mouseklick"? Is it the JS onclick event? Or something related with WebDriver?

We have a angular 2 app and clicking on buttons, text fields or menu entries etc. has no effect at all, with all versions greater than stable 2.44.4 where everything worked fine.
If I could collect more detailed information's about this issue for you, please let me know (e.g. trace, etc.) !

Hello ! , i can confirm this, on
- Cog 0.18.4
- WPE WebKit 2.46.6

I built the two packages from tarball releases on ubuntu 22.04 native x64 , i have the same problem , the onClick event never fires, using this simple demo : https://unixpapa.com/js/testmouse.html i can see that mousedown and mouseup event fires correctly but no onClick event , 

the onClick event fires correctly on chrome, i havent checked with touch screen , ill test it on my iMX8 after i cross compile it.

Hello,

did you find the root cause and is there already a fix available or is there a chance to one in near future?
Is this a bug in WPE WebKit or Cog? This is preventing us to update to latest WebKit WPE version, so we would be happy to get this done.
Please could you provide us a short status of the issue. Thank you in advance.

I can reproduce with cog, but not with MiniBrowser, and only with wayland platform, gtk4 works fine, so I think this is a bug in cog wayland implementation.
