Have a new project with one action to compile a Delphi 10.2 project. Everything looks OK, but when I run it, I’m getting a “An unhandled exception (‘Type mismatch: ‘Action.MajorVersion’’) occurred in FinalBuilder8.exe [600864].”
This was action was copied from another project and then tweaked. I created a new action that is basically the same and it works. Comparing the DSL, I see
action.script
begin
name = BeforeAction
script \>
beginscript
Action.MajorVersion = VERSION1\_MAJOR
Action.MinorVersion = VERSION2\_MINOR
Action.ReleaseVersion = VERSION3\_RELEASE
Action.BuildVersion = VERSION4\_BUILD
endscript
scriptlanguage = VBScript
end
in the one that fails. Defining the variables make the error go away. However, I cannot find where in the action dialog tabs that this is accessible to remove/edit/etc. Is it an artifact from FB7? Reporting this since a more user friendly error than an unhandled exception is probably desired.

What version/build of FinalBuilder 8 is this. Undefined variables shouldn’t cause an av. To edit the script, select the action, then look at the script editor tab (if you have trouble finding it, use the view menu, script editor).

FinalBuilder 8.0.0.2370
View Script Editor is what I needed. Removed script and it is happy. But above version does show the unhandled exception dialog.

I believe it was fixed after that version, I’m not able to reproduce the problem with the current release.

OK, thanks. I’ll upgrade after our next release.
