a beforeopen script on a data set can not include a line feed inside a quoted string so, for example, this.querytext = "select whatever from table where ...[ all the select query must be on a single line]"
this makes maintenance of the query very difficult when it is complex.

with 2.3.2, the beforeopen script window showed an error flag, with 2.5.2 no error is shown until the report is run.
note, i don't want the error flag: i want to be able to enter a multiline script!

reproducible: always

steps to reproduce:
1. set a dataset beforeopen script to this.querytext = "select whatever 
from table" (with the line break)
2. run the report: the script will be reported as an error.
3.
the before open script use java script syntax. so if you want a string to split to more than one lines you should use "+" operator.
thanks
