CommandButton : EL expression for Update

[denisduval75]

Hello,
On a commandbutton, I want to condition the value 'update' according to a boolean, like this:

If boolean is true: <p: commandButton ... update = "a b c">
If boolean is false: <p: commandButton ... update = "d e f">

I do not know how to code the EL expression. Something like this:

<p: commandButton ... update = "# {bean.boolean == true: a b c, bean.boolean == false: d e f}"

Thanks a lot for your help.

For a JSF beginner it can be confusing, but you can simply use shorthand if (like mentioned above) to return 2 different strings:

Code: Select all

#{bean.boolean ? 'a b c' : 'c d e'}
