How to enable/disable primefaces commandButton?

Question

I have two buttons on screen. When page first loaded I want to button2 is disabled until button1 is clicked. When button1 is clicked, button2 must be enabled.

I tried:

<p:commandButton value="Normalize"
    actionListener="#{mainTable.normalize}" update="dataTable"
    id="normalize" styleClass="ui-priority-primary"
    style="font-size: 14px">
    <f:setPropertyActionListener value="#{true}"
        target="#{mainTable.disable}" />
</p:commandButton>
<p:commandButton value="To Verify Next->" action="verify.xhtml"
    actionListener="#{mainTable.verify}" id="next"
    styleClass="ui-priority-primary" style="font-size: 14px"
    disabled="#{!(bean.disable)}">
</p:commandButton>

My bean:

@ManagedBean
@SessionScoped
public class MainTable
{

    private boolean disable;

    public MainTable()
    {
        disable = false;
    }
    public boolean isDisable()
    {
        return disable;
    }

    public void setDisable(boolean disable)
    {
        this.disable = disable;
    }
}

But it doesn't work. When I clicked button1, button2 is still disabled. What is wrong?

Debug your code. Is the `disable` property being set? Also why are you using `f:setPropertyActionListener` tag when you have the `normalize` action listener? Just set it to true when `normalize` is called. — Aritz, Oct 04 '13 at 07:55
@XtremeBiker I tried it also ( setting it in normalize method) but it is not working also. — yetAnotherSE, Oct 04 '13 at 08:21
Sorry it is about line: disabled="#{!(bean.disable)}"> it should be mainTable.disable Problem solved. — yetAnotherSE, Oct 04 '13 at 08:27
Glad to see it worked. Try to publish an answer for your own question instead of editing the question itself to publish the answer there. — Aritz, Oct 04 '13 at 08:43
I think instead of `disabled="#{!(myTable.disable)}">` you mean `disabled="#{!(mainTable.disable)}">`? If that's the case, you might edit the question, or add your own answer and accept that one. — Wisco crew, Apr 23 '14 at 17:17
This question appears to be off-topic because it is about thoughtfulness mistake. — yetAnotherSE, Jun 06 '14 at 08:03

Try to update the second button on clicking the first one like the dataTable

You should replace the bean in disabled="#{!(bean.disable)}"> with mainTable => disabled="#{!(mainTable.disable)}">

Any error message? Maybe try to wrap the two buttons in a container like the primefaces outputPanel (`p:outputPanel`) – JulianG Oct 04 '13 at 08:02
Did my answer helped you? I see you solved it, but without updating the button it shouln't be working. – JulianG Oct 04 '13 at 08:34

You should swap 2 buttons in a Outputpanel, and update this outputpanel alter for next button, like this:

<p:outputPanel id="pnltest">
  <p:commandButton value="Normalize"
    actionListener="#{mainTable.normalize}" update="dataTable,pnltest"
    ...
  </p:commandButton>
  <p:commandButton value="To Verify Next->" action="verify.xhtml"
    actionListener="#{mainTable.verify}" id="next"
    ...
  </p:commandButton>
<p:outputPanel>

How is this supposed to solve it? This issue is not related with `rendered` attribute, but with `disabled` one. – Aritz Oct 04 '13 at 08:00
@XtremeBiker This is my experience, and it works fine for some project :-) – Rong Nguyen Oct 04 '13 at 08:03
@XtremeBiker in some cases, OP example is work fine, but some cases i must do as i answer. – Rong Nguyen Oct 04 '13 at 08:05
But you're updating the whole panel when there's no need to do it... Just updating the target command button should work. – Aritz Oct 04 '13 at 08:05
@İlknurKabadayı Your code and my code are work fine, i have just tested! – Rong Nguyen Oct 04 '13 at 08:26
@İlknurKabadayı I don't know your environment, i tested with liferay 6.1.2 in portlet environment. – Rong Nguyen Oct 04 '13 at 08:28
