    That is roughly what I am doing. I will ask you to peer review the patch when it is done.

    I had a client reported the following JME problem. Please help to identify the issue.
    The JME editor now seems to work perfectly; however, the question engine does not recognize either of the correct answers when they are given. I assume this is a problem with the pattern match mechanism, since there is a function in the JME Editor to acquire the SMILES string and it is identical to the SMILES string entered in the question (although the question version requires escape characters, as per the manual: "

    I am running into issues with this plugin on my moodle 2.6.4 installation. I have installed version 1.4 following the instructions listed here however when I create and preview a question of this type in moodle the JME applet does not load.

    I see in my access logs that a request is being made for /question/type/pmatchjme/jsme/jsme.nocache.js

    This file(s) are not included in this plugin. I have the jmol/jsmol filter installed in my moodle installation. Any help would be appreciated

    Great spot jason. Sorry about that.

    It turns out that the zip in the Plugins directory is a bit out of date.

    The git repository is more up to date but there are two fixes that still need to be deployed to it.

    I'm in the process of applying and testing the fixes. Then I will push to the repository and get the plugin zip in the plugins database updated.

    I've updated the git repository with the latest fixes (There was a javascript problem in IE 8) You'll find the JSME folder with the jsme.nocache.js file in there.

    If you're comfortable with git just pull the latest version, visit admin > notification and pmatchjme will be updated (the caches need to be flushed to get the latest javascript files).

    I'll look at getting the version in the Moodle plugins directory changed.

    Thanks Colin. The version of github works. I should have spotted it sooner. I was assuming the zip here and on github were identical.

    Is a version for Moodle 3.7 planned? We have problems with this type of question on our installation. The question type gives no points or other reaction when answering questions.

    I have not yet had time to test my plugins with Moodle 3.7. It surprises me if it has stopped working, because I don't think anything significant changed in 3.7 that would affect this question type, so I don't know why it is not working for you.

    I am also having difficulty with this plugin under Moodle 3.7.1. The JSME Molecular Editor shows up OK, and allows drawing the answer structure, but upon submitting the answer, the question page is re-drawn with red "Please enter an answer" text below the editor area. I can't find anything obviously alarming in the Apache log files. This happens with both Boost and Clean themes. Maybe co-incidentally, a similar issue is also affecting my qtype_fwstructmatch questions in 3.7.1 (these worked fines in 3.5).
