ScriptEval is an operator on a model object (the context) that lets you have expressions as data and evaluate them.
You must state the valid Return type.
let info=self.ScriptEvalCheck(false,Double, self.SomeString) in ( vSomeStringResult:=(info='ok').casetruefalse(self.ScriptEval(false,Double, self.SomeString).asstring,info) )
The above code will check if the self.SomeString value is a valid expression in the context of self and whether it returns a double - if so, the result will be converted to string and assigned to vSomeStringResult. If it's not a valid expression, the problem with the expression will be in vSomeStringResult.
Using the default model:
0.2222+self.SomeInt+self.SomeDateTime.Ticks
