copied!<p>If I understood correctly you want to disable the <em>New</em> button when you click on the <em>Open</em> button.</p> <p>You don't need to put your toolbar into a form, you can disable that button through JavaScript:</p> <pre><code><p:commandButton type="button" value="New" icon="ui-icon-document" widgetVar="disablethis"/> <p:commandButton type="button" value="Open" actionListener="#{bean.anyMethod}" update=":frm" onclick="disablethis.disable()"/> </code></pre> <p>Also try referencing your form with <code>:frm</code> in your <code>update</code>.</p> <p>You should also consider changing the <code>onclick</code> action depending on your requirements to:</p> <ul> <li><em>onstart</em></li> </ul> <p>Client side callback to execute before ajax request is begins.</p> <ul> <li><em>onclick</em></li> </ul> <p>Client side callback to execute when button is clicked.</p> <ul> <li><em>onsuccess</em></li> </ul> <p>Client side callback to execute when ajax request succeeds.</p> <ul> <li><em>oncomplete</em></li> </ul> <p>Client side callback to execute when ajax request is completed.</p> <p><strong>EDIT</strong></p> <p>If you want to solve this without explicit JavaScript you need to have a flag in your backing bean (as you already discovered), indicating is the Open button disabled or not. Then call the <code>anyMethod</code> of your backing bean (which will set that flag inside as you described) and finally update the <em>Open</em> button:</p> <pre><code><p:commandButton value="New" action="#{bean.anyMethod}" icon="ui-icon-document" update="button1"/> <p:commandButton id="button1" value="Open" type="button" disabled="#{bean.disabled}"/> </code></pre> <p>Have the appropriate getters/setters in your backing bean, and set the flag in <code>anyMethod</code>:</p> <pre><code>private boolean disabled; public boolean isDisabled() { return disabled; } public void setDisabled(boolean disabled) { this.disabled = disabled; } public void anyMethod() { if (disabled) { disabled = false; } else { disabled = true; } } </code></pre>
