Joomla.renderMessages - Cannot read property 'joomla.jtext' of null

[Wojton]

Steps to reproduce the issue

  var messages = { "message": ["Message one", "Message two"],
                            "error": ["Error one", "Error two"]
                        };
 Joomla.renderMessages(messages);

   jQuery.ajax({
                    url: "index.php",
                    type: "POST",
                    data:
                    { 
                        option: "<?php echo $option ?>",
                        task: "messageform.sentMessage",
                        params: "<?php echo $this->params64 ?>",
                        "<?php echo JSession::getFormToken() ?>": '1',
                        msg:jQuery("#gs-message").val()
                    },
                    dataType: "JSON",
                    success: function(json){
                        var messages = { "message": ["Message one", "Message two"],
                            "error": ["Error one", "Error two"]
                        };
                        Joomla.renderMessages(messages);
                      //  Joomla.renderMessages(json.messages);

                        if(json.data == "message_send"){
                            jQuery("#ga-jq-submit-message-form").fadeOut('fast',function(){
                                jQuery(this).remove();
                            });
                        }
                    }
                });

I can't replicate this! Please make sure that core.js is loaded in your view!

code I used:

   jQuery.ajax({
                    url: "index.php",
                    type: "POST",
                    data:
                    { 
                    },
                    dataType: "JSON",
                    success: function(json){
                    }, error: function() {
var messages = { "message": ["Message one", "Message two"],
                            "error": ["Error one", "Error two"]
                        };
                        window.Joomla.renderMessages(messages);}
                });

I can confirm this issue exists. And since I had not enough time to dive in, I am using a workaround that is making a useless JText:: script() call in my layouts.

@Wojton please enable Debug mode, and post here the javascript error again?

[tonypartridge]

Is this not caused by not having the system-messages container rendered?

[andrepereiradasilva]

could this also be related to the progressive cache issue like https://github.com/joomla/joomla-cms/issues/16375#issuecomment-305864460 ?

1. The JHtml::_('behavior.keepalive'); inside the mod_login template file is not being processed when cache in conservative mode.

[Fedik]

it should be fixed with #16488

@Wojton can you please test #16488 if it fixes this Issue & in so close this Issue – thanks.

[andrepereiradasilva]

https://github.com/joomla/joomla-cms/pull/16488 should resolve the js error

But there is the issue of the joomla.jtext json could not being loaded in certains conditions and that could be the same issue as https://github.com/joomla/joomla-cms/issues/16375#issuecomment-305864460

@Wojton is this used in a module? does this happen with Progressive cache enabled?
