Question

I have a datatable which provides objects from a list. Within this data table I would like to use a tag like p:columns(primefaces) which provides strings from a list that represent the name of a field.

I will now need a subexpression to be able to use the dynamic field name like:

#{entry.#[column.fieldName}}

Is there any possibility to do this in JSF2?

Answer 1

If entry has get/set accessors for columns values, you could use this syntax :

#{entry[column.fieldName]}

In EL you can use two syntaxes to access to the value of the “lastname” property of an object :

#{myObject.lastname}
#{myObject["lastname"]}
