  • Open `GetHomeSampleData` object and check the rules section to see if there is a `parm` rule there. If it's commented or you see none then check the history of that object for modifications or reimport it again – gusbro Aug 10 '22 at 15:35
  • @gusbro yeah I don't see the parm rule but I don't have any rule to begin with, the other fellows in my group also don't have the parm rule but their app still run normally! – dragonquila Aug 11 '22 at 08:10
  • Check the events section of the `Home` webpanel at line 19. What does it say ? – gusbro Aug 11 '22 at 15:31
  • @gusbro &HomeSampleData = GetHomeSampleData() – dragonquila Aug 11 '22 at 15:34
  • I don't think the problem is in the Home webpanel. All the error just point to the GetHomeSampleData DP – dragonquila Aug 11 '22 at 15:36
  • Ok, I didn't know `GetHomeSampleData` was a dataprovider. In that case it does not need a `parm` rule because the output is implicit (defined in the `Output` property of the dataprovider). I would try creating a new DataProvider, set the output property just as it is defined in the problematic dataprovider and put some dummy data, then change the statement in your `Home` webpanel at line 19 to point to this new dataprovider. It seems that somehow the signature for `GetHomeSampleData` got corrupted. – gusbro Aug 11 '22 at 15:57
  • It doesn't work, maybe my computer has some problem? I have tried to reinstall both genexus and WWP but it seems like this never work for me – dragonquila Aug 11 '22 at 16:21
  • I am certainly sure its not your computer, but I have not enough information to help you either. Which version of GeneXus are you using, including the build number as shown in Help->About ? – gusbro Aug 11 '22 at 16:24
  • I'm using GeneXus 17 trial version, it's the latest version and also the latest trial version of WWP. I don't think my installation have issues since I and my fellow follow the same process but I got this bug and he didn't :( – dragonquila Aug 11 '22 at 16:35
  • I don't even change anything after installing WWP, and how come this error appear – dragonquila Aug 11 '22 at 16:36
  • This is all about my version. GeneXus Trial - Version: 17.0.162473 U10 – dragonquila Aug 11 '22 at 16:37
