Approval issue created: CONTRIB-10340

I identified an issue when using this course format plugin on Moodle version 5.0.1. During course editing, a failure occurs in the page editing functionalities (dropdown), resulting in JavaScript errors.

After analyzing the problem, I found that it is related to the component.init call in the templates/local/content module. In Moodle 5.0.1, the third parameter (sectionreturn) may not be defined, causing an empty value to be passed to the function. This leads to execution errors and breaks the course editing interface.

It is important to note that this behavior does not occur in more recent Moodle versions (tested from 5.0.6+), where this parameter is already properly handled.

Original code:
{{#isediting}}
{{#js}}
require(['core_courseformat/local/content'], function(component) {
component.init('#page', {}, {{sectionreturn}}, {{#pagesectionid}}{{.}}{{/pagesectionid}}{{^pagesectionid}}null{{/pagesectionid}});
});
{{/js}}
{{/isediting}}


Applied fix:
I implemented a check to ensure that if sectionreturn is not defined, null is explicitly passed, preventing the JavaScript from breaking:
{{#isediting}}
{{#js}}
require(['core_courseformat/local/content'], function(component) {
component.init(
'#page',
{},
{{#sectionreturn}}{{.}}{{/sectionreturn}}{{^sectionreturn}}null,{{/sectionreturn}}
{{#pagesectionid}}{{.}}{{/pagesectionid}}{{^pagesectionid}}null{{/pagesectionid}});
});
{{/js}}
{{/isediting}}


With this adjustment, the issue was resolved in the affected environment, restoring normal course editing functionality.

I suggest considering adding this validation to the plugin to ensure compatibility with older Moodle versions, especially 5.0.1.
