BUG: Item type property not displayed in Report

Ivan Galik said:

However one of the properties is not displayed in the Report:

It's weird, I guess somebody from developers will have to check what's happening internally.

In the past I reported bug (discussed also in this forum), when expressions results were not available in reports (I hope I remember it right). But in your case, 3 expressions look nearly the same, but only one does not work.

looks to me like wrong expression… (last one)
this correction works fine for me

IIf(System.String.LastIndexOf(this.GetElement().GetDisplayString("Level"),"-")>=0,System.String.Substring(this.GetElement().GetDisplayString("Level"),System.String.LastIndexOf(this.GetElement().GetDisplayString("Level"),"-")+1,(System.String.Length(this.GetElement().GetDisplayString("Level")))-(System.String.LastIndexOf(this.GetElement().GetDisplayString("Level"),"-")+1)),"")

please verify it

now it works. thank you

funny thing is that the wrong one worked fine to be displayed in properties but not in the report.

could you please have a look at this post of mine which is related

I've come across that puzzle, where an Expression works as an Item Type property but fails in a Report definition.  The solution is to be very precise with the Expression syntax.

Unfortunately there's not an Expression debug tool.  Or to put it another way, the Expression Builder is not very informative when we get things wrong.
