[xwiki-users] How to made readonly text input

Hello, I reuse code from Polls (proposal for a voting system) to made a text input:

println(doc.displayEdit(cclass.get(field.getName()), "${doc.getFullName()}_", survey)) After I try to made it read only: field.setStringValue("readonly","readonly") But it doesn't work: output html doesn't contain /readonly/ attribute.

Who can help me? Regards, Arnaud Bourrée
