I try to use expression in a text field, and the language is set to groovy, what I input is a very simple if else statement

if ($P{P_TFE_TYPE} == null || $P{P_TFE_TYPE} == ""){   "abc"}else{   "def"}.[/code]

but this already throw exception as

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
calculator_RPT0010_1542190583832_137322: 472: unexpected token: if @ line 472, column 22.

what is the problem?

I see a red underline under the opening {, and the tool tip is

missing EOF at '{'

if I use expression like

($P{P_TFE_TYPE} == null || $P{P_TFE_TYPE} == "")?"abc":"def"[/code]

it can compile, everything run as expected.

I know I can use ?: operator but don't want to as my if..else if condition is quite lengthy and complicated in reality, and feel hard to see if use tenary operator ?:
