Hi,

I’m new to Gatling and scala, and have now been struggeling for too long with following:  
In a request response I want to pick up the “data-lessonstatus” string value, and make some simple char replacement before storing it as session string var “lessonStatus”  
But there seems to be some type mismatch: _.saveAs_ takes a string, but _.transform_ gives a option[String]

.exec(http(“request\_6”)  
.check(regex(""“data-lessonstatus=’([A-Z,0-9,&,#,;]\*)’”"")  
.find.transform( s =\> {  
s.get.replaceAll(“Ö”, “Ö”).replaceAll(“Å”, “Å”)  
s  
}  
.saveAs(“lessonStatus”))

any hints welcome!

Hi,

.check(regex(""“data-lessonstatus=’([A-Z,0-9,&,#,;]\*)’”"")  
.find.transform( _.map(_.replaceAll(“Ö”, “Ö”).replaceAll(“Å”, “Å”) ))  
.saveAs(“lessonStatus”))

Is this working ?  
Do you get it?

cheers  
Nicolas
