Y.one(...) is null

[fabianp60]

Hi Andre, I am a student of software engineering and am trying to use your DASIS package blocks, but I am getting an error when I try to configure the learning paths, the problem is I can not create a learning path and believe it is due to a error with the YUI module since Firebug tells me that Y.one(...) is null. Could you give me your help? I am using Moodle 2.1

Hi Fabian,
could you decribe your problem more precisely?
What exactly is your interaction?
Did you tried it with other browsers?
Cheers, Andre

Hi Andre I already solve the problem by myself, I was trying to create learning paths logged as a teacher, when I read de access.php file I understand that the teacher can't create learning paths, only admin.

The problem was in the semantic_web.js file when used in the edit_form.php logged as a teacher, the link with id="id_delete_path" was not created because capability of the teacher. And when semantic_web.js try to execute:

Y.one("#id_delete_path").on("click", removeLearningPath);

an error occurs because the object Y.one("#id_delete_path") is null, then I replace that line by:

var deletePathObj = Y.one("#id_delete_path");
if(deletePathObj) {
deletePathObj.on("click", removeLearningPath);
}

delete my browser and Moodle themes cache, login as a teacher again and update the plugin edit page, that works for me.

I apologize for my bad English, I have not much experience writing it

Greetings and thanks for replying

I thought the teacher could not create learning paths because a javascript error, but then I realized that the teacher could not create paths because have no capabilities

You can change the capabilities of blocks is their block settings or even in the access.php file.

I am a begginer using github, I still dont know how to make forks and pulls, I just download your code from Moodle plugins page and modify it using netbeans :(

I can make a pull or modification just using this web? the change implies only one line in semantic_web.js file

I Just did it!! ... what a nice tool is github

Cheers, Fabian

Fine! I'm also new to github to collaborate. But it seems to work fine :-)
