404 View not found [name, type, prefix]: about, html, Administrator

Hi schnuti,
I just installed Jdump on the last 4beta1dev of Joomla! (nighty build 2020/02/23) and have that error when trying to display the component page.
The plugin is enabled and at the first position of system plugins.
Thanks,
fontanil

Hi @fontanil
did you download the correct package from the code here?
jdump_package_4_0_0_jbeta1.zip --- tested with Joomla 4.0 beta 1
I do not have the latest 4.0.0 beta1 - but only a few days old - and it still works as expected.

Hi schnuti,
Yes, I used "jdump_package_4_0_0_jbeta1.zip"
Joomla! 4 beta1 dev updated this morning, on PHP 7.4.2

In the Joomla beta version I have, there are some bugs e.g. when trying to set any component options I get a "Invalid controller class: display" Related or is this solved by now?
I'll test with a new Joomla instance in the next days.

Thanks !

I made a quick test sitting on my sofa with the Jooma 4.0 beta package from today 23/2.
No problems installing the JDump package downloaded from here.
It looks more like the first issue reported where this JDump was installed to a Joomla 3 version.
Component Not Found Error
I tested on a win10 with xampp and PHP 7.3.12 but that shouldn't be a reason.

I tested yesterday J!dump on a website: it works.
Only the main component page is not displayed with error 404 or opening administrator main page.
I tried to understand why and did'nt find. :-(

Hello.
I use jdump_package_4_0_0_jbeta1.zip on
PHP 7.3.16
MySQLi 10.1.44-MariaDB
Joomla! 4.0.0-beta3 Beta [ Mañana ]

In backend the J!dump Component is redirected at index.php, no options are displayed.
The JDump plugin is on and ordered as being first.

In frontend a popup is opened at the /index.php?option=com_jdump&view=tree&format=raw but the page is empty.

Hi,

Always the same 404 error on remote sites (two different servers) with joomla! 4.0 RC2 and RC3dev (PHP 7.3 to 8.0).

404 View not found [name, type, prefix]: about, html, Administrator
3 | Joomla\CMS\MVC\Controller\BaseController->display() | JROOT/administrator/components/com_jdump/Controller/DisplayController.php:47

No error on a local server Wampserver 64 (PHP 7.3 to 8.0.7)

Hi,
Here the "factory->createView fails on my remote servers and succeds on my local Wampserver 64
protected function createView($name, $prefix = '', $type = '', $config = array()) { $config['paths'] = $this->paths['view']; return $this->factory->createView($name, $prefix, $type, $config); }
The file is "libraries/src/MVC/Controller/BaseController.php"

Hi,
I found the problem.
By renaming the file "HTMLView.php" to "HtmlView.php", the 404 error disappeared ( HTML <> Html on the remote servers ).
We need to replace "setVar" by "set" in "RawView.php" line 48
Last problem: the "popup" button doesn't open a popup but replaces the about page by the results page.

I changed in HtmlView.php line 39 and have now a popup

$toolbar->LinkButton('link')
		->text('Popup')
		->url('index.php?option=com_jdump&view=tree&format=raw&closebutton=0');

by
$toolbar->appendButton( 'Popup', 'default', 'Popup', "index.php?option=com_jdump&view=tree&format=raw&closebutton=0" );
