[Can we create a sftp connection for exporting report from jasperserver ?]

It's still an open issue

[Issue with Parameters that are from a List]

Hello Irewell,

"When I run the report I get this error.

        at java.lang.Thread.run(Thread.java:595)
net.sf.jasperreports.engine.JRRuntimeException: Invalid type + java.lang.String
for parameter A used in an IN clause; the value must be an array or a col
lection."
It caused by Multiple options, so if you used the Single option with the syntax: "where $X{IN,table.value,AA}", it was wrong. Maybe you should try to use  like this:
where $P{Parameter} = '#string' 
Hope It's helpful
