Title: Expression Language - Bug reading brackets? [solved - user error]
Post by: Ferdi on August 22, 2020, 07:29:33 am

I am trying to build a field that shows me

• Song Title, if the rating is 0
• Song Title (Rating), if the rating is greater 0

I use this to achieve that: IfElse(isequal([Rating], 0, 2),[Name],1,[Name] ([Rating]))

Output is correct when a rating exists, but includes a closing bracket if no rating exist. For example:

• All Our Songs), with zero star rating
• Life In Vain (4), with a 4 star rating

Is that a bug or a user error?

User error :)
brackets are a part of the expression language, so, those that you want to be part of your output must be escaped, like so...

IfElse(isequal([Rating], 0, 2),[Name],1,[Name] /([Rating]/))
