    <p>I am using jsf h:commandButton . My Requirement is that based on value of Button , i have to handle the action . I have used following </p> <pre><code>&lt;h:commandButton id="raisecm" render="@all " styleClass="btn btn-primary" execute="@this" value="#{scenarioConfigurationMB.status}" actionListener="#{scenarioConfigurationMB.createPatchingCMTicket()}" onclick="if(this.value=='Edit Ticket'){this.form.target='_blank';}"&gt; &lt;/h:commandButton&gt; </code></pre> <p>Here status can be either "Create Ticket" or "Edit Ticket". If status is "Create Ticket" i have to create a ticket in Backing Bean method "createPatchingCMTicket" , otherwise if the status is "Edit Ticket" i have to return open a page in new tab showing its details.</p> <p>Method in backing bean is as:</p> <pre><code> public String createPatchingCMTicket() { System.out.println("***********************Ticket ID"+ ticketId); ticketId="123"; System.out.println("Checking Status of CM Ticket For Patching ......"); if (status.equals("Edit Ticket")) { System.out.println("*********Status is \"Edit Ticket\""); try{ ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext(); externalContext.redirect("/cm/view_ticket.xhtml?changeTicketId="+ticketId); } catch(Exception e){ System.out.println("Redirection Failed........`enter code here`..................***************"); throw new FacesException("Redirection failed......"); } System.out.println("********Redirected........"); return null; } System.out.println("Creating Ticket.............***********"); log.info("Creating CM Ticket For Patching ......"); //Code for Creating Ticket </code></pre> <p>}</p> <p>If I am using above concept in h:commandButton , if the status is "Edit Ticket" , it is working fine and redirecting to the other url in new tab but only for first click and if I again click on 'Edit Ticket' it is opening the same base page in new tab and not redirecting to new page. </p> <p>I have struggled a lot to resolve this unexpected issue. Kindly help.</p>

    2. CO@HatemAlimam : status is just a string variable , for that getter and setter are present in backing bean. "status" represents the value printed on the command button.

    3. CO@learner...first thing first. `<h:commandButton>` doesn't have inbuilt `ajax` capability. So it doesn't have `render`and `execute` attributes.So, Please go thorough documentation (http://docs.oracle.com/javaee/7/javaserverfaces/2.2/vdldocs/facelets/) first and get to know `API` existed in the documentation

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
