selectBooleanCheckbox checked

[Gantz]

hi im using a table with a selectBooleanCheckbox column, i have to indicate if a item is already saved in the database and i want to show the selectBooleanCheckbox cheked but the only way i found to do it is this

Code: Select all

<p:selectBooleanCheckbox value="#{unidadesController.asignadosFromDB.contains(item) ? true:false}">

but when i try to perform an ajax action gives this error

Code: Select all

value="#{unidadesController.asignadosFromDB.contains(item) ? true:false}": Illegal Syntax for Set Operation

theres another way to show the selectBooleanCheckbox cheked ??? or a way to solve this error?
thanks!

Tried making it readonly or disabled? Since you can never manipulate it

[Gantz]

i cant put it disabled because i do manipulate the checkbox, when the user selects the checkbox it performs an ajax action

"value" requires a ValueExpression (property + getter/setter)

Hmmm if you do manipulate it, it is strange that you expect a conditional expression would work. Thomas is right then... Use a pure value expression then
