title: Invoking methods with parameters by EL in JSF 1.2
body: <p>I am using a datatable and for each row I have two buttons, an "Edit" and a "Delete".</p>
  
  <p>I need these buttons to be read-only, i.e. disabled, if a certain condition is met for the row in question. I have seen in <strong>JSF 2</strong> that it is possible to pass parameters to method calls. Is there anything equivalent in JSF 1.2?</p>
  
  <p>Ideally what I would like it something like (the looping variable is <em>loop</em> and there is another bean, <em>helper</em>, which contains the method I would like to invoke):</p>
  
  <pre><code>&lt;h:commandButton value="Edit"
                     disabled="#{helper.isEditable(loop.id)}" /&gt;
  </code></pre>
  
  <p>In this case it does not make semantic sense to add an <em>isEditable</em> attribute to the bean and it is not practical to create a wrapper Object around the bean.</p>
  
  <p>Thanks in advance.</p>
