Question

I want to disabled a commandLink with this condition:
<p:commandLink id="buttonchoix" value="choisir" disabled="#{editCommandController.result < car.stock}" />

but it generated for me this error (in French):

Error Parsing /vues_admin/editCommand.xhtml: Error Traced[line: 88] La valeur de l’attribut “disabled” associé à un type d’élément “null” ne doit pas contenir le caractère ‘<‘

How can I achieve this?

Answer 1

use lt (less than) instead

<p:commandLink id="buttonchoix" value="choisir" disabled="#{editCommandController.result lt car.stock}" />
