    copied!<p>I am using JSF Myfaces Impl 1.2 without tomahawk and other libs :</p> <p>I am using different styles + images to show JSF Error messages, find below a sample.</p> <pre><code>&lt;h:panelGroup rendered="${adminBean.showErrorIcon==2}"&gt; &lt;table width="375" align="center" class="InfoMsg" border="1" cellspacing="0" cellpadding="0"&gt; &lt;tr&gt; &lt;td&gt; &lt;table width="375" align="center" class="InfoMsg" border="0"&gt; &lt;tr&gt; &lt;td width="50"&gt;&lt;img src="static/images/info_icon.gif" width="40" height="40" border="0" /&gt;&lt;/td&gt; &lt;td width="325" align="left"&gt;&lt;h:messages layout="table" errorClass="InfoMsg" /&gt;&lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; &lt;/td&gt; &lt;/tr&gt; &lt;/table&gt; </code></pre> <p></p> <p>Based on the int variable of the Backing Bean , I am displaying a diff image and the corresponding FacesMessage(s) in the screen - only 2 cases - error or an information.</p> <p>I am using the below code to set the variable of the Backing Bean </p> <pre><code>//Checking if there are messages! log.debug("Checking if there are messages to be shown ]"); if(getShowErrorIcon()==99){//Set only if the value is still the default : log.debug("getShowErrorIcon was DEFAULT - Changing it ]"); Iterator&lt;FacesMessage&gt; messages = FacesContext.getCurrentInstance().getMessages(); if(messages != null &amp;&amp; getShowErrorIcon()==99){//Set Error/Info for messages that are not added here : while(messages.hasNext()){ log.debug("There are ***messages***"); FacesMessage aMessage =(FacesMessage) messages.next(); if(aMessage.getSeverity().compareTo(FacesMessage.SEVERITY_ERROR)==0){ setShowErrorIcon(1); break;//just once is enough } if(aMessage.getSeverity().compareTo(FacesMessage.SEVERITY_INFO)==0){ setShowErrorIcon(2); break; } } } }//if it is not default, then something has been set already, why again? </code></pre> <p>Now the problem I have is , There are FacesMessage(s) that are added by the MyFacesImpl - like the required=true and the custom validator messages which are added during PROCESS_VALIDATION Phase, These are not shown in the screen since my integer variable of the Backing Bean is not set , and since the INVOKE_APPLICATION Phase was not called (and that means the above code was not called!!!) </p> <p>How do I resolve this? Or Whats the best way / Where's the best place to place the above checking code ?</p> <p>Appreciate your help.Thanks!</p>
