Summary of Changes

There are several errors introduced by PR #47495

• Template might have already has language item use for title of the layout, but the PR dropped support it, so it is kind of backward incompatible change. This PR restored that behavior. The language item (if available) in template language file has highest priority
• The PR changed the value of the option associated to the layout, added the view associated to the layout to value of the option. I can see the purpose of that change, but it causes two things: The selected layout before will be lost (not selected anymore) and also the selected layout could not be realized by our view system when rendering layout.

Testing Instructions

• Use Joomla 5.4
• Copy two files default.php, default.xml from components/com_content/tmpl/article folder to templates/cassiopeia/html/com_content/article folder (please create the folders in the template if it does not exist before)
• Rename the two files to alt.php and alt.xml
• Edit the file alt.php, change the code to below so that the layout is easy to relialize:

<?php
echo 'Alt Article Layout';

• Edit the file alt.xml, find layout element and change it to:

<layout title="Alt Article Layout Title" option="Alt Article Layout">

• Create a menu item to link to Category Blog menu item type. In the Options tab of the menu item, look at Choose a Layout parameter and make sure the text option for the new layout we added earlier has text text entered in the option attribute of layout element displayed (in this case, it is Alt Article Layout). Select that Alt Article Layout option for the parameter
• Access to the menu item above, and from there, access to an article

Actual result BEFORE applying this Pull Request

• The default layout from article view still being used to display the article, not the custom layout which we created and selected in Choose a Layout parameter of the menu item above

Expected result AFTER applying this Pull Request

• The layout which we selected for Choose a Layout parameter of the menu item is used to display article. When access to article , we see the text Alt Article Layout which we added to the custom layout. Please note that after apply the PR, you need to edit the menu item and reselect the layout to see the change.
