I have successfully imported Common Cartridge v1.1 into Moodle v2.3.
The cartridge consists of a number of LTI links.
The links to the Tool Provider import correctly but the TP requires a custom parameter. The LTI markup is as follows:
[see lti_snippet.txt attached]
If I use Chrome Developer Tools I can see the POST data sent to the Tool Provider and there is no custom parameter.
If I look at the LTI link in Moodle, there is no custom parameter and none in the database either. The value is "0".
If I create the LTI link manually in Moodle, it works perfectly.
If I then backup the course as Common Cartridge v1.1 it exports everything except the custom parameter.
Looking at the PHP code, it appears that the <blti:custom> element is ignored during backup/restore.
Is this true? Does the CC backup/restore in Moodle ignore the LTI <blti:custom> element ?
Thanks in advance for any confirmation or advice.
