Ternary Operator In Set Value Not Working ASP .NET

Wappler General Bugs
#1

Wappler Version : 4.9.1
Operating System : W10
Server Model: ASP .NET
Database Type: MSSQL

{{$_POST.strWeekDay == 'Monday' ? 1 : 5}}

Putting this in a SET VALUE step returns an error: Specified cast is not valid.
If I remove the ternary operator, the output of the condition is True - which seems weird as it should be true.

Wappler 5.0.3 Released
#2
#3

Does it also tell a filename/linenumber in the stacktrace of the error?

#4

Trying a different method to do an explicit cast, here the update:

DMXzone.ServerConnect.zip (56.6 KB)

I can’t reproduce the error myself, so I don’t know exactly what goes wrong and can’t test it.

The error is in the expression parser, original code was:

(bool)left() ? middle() : right()

changed it now to:

Convert.ToBoolean(left()) ? middle() : right()
