Hi,

i have found some minor Bugs and solutions for them and want to share them her with you:

problem:
The lines in the line plot are not showed.

solution:
I get the message some array index was zero. I found the lines were they getting decrementet in file /components/plot/line/plugin.class.php. Just take this lines out to solve the Problem.

problem:
The report logs the information without setting the modul field in the log table. So you can not find the log entrys belonging to the plugin.

solution:
Just add a string(for example "configurable_reports") as second parameter to the add_to_log commands in the files:
viewreport.php
editcomp.php
editplugin.php
editreport.php

Some more issues which are only in the 1.9 Version:

problem:
When importing a report it is always as a report on the main page.

solution:
Course id is missing here so the default id is taken for every import. Just add following lines to import_form.php:

$mform->addElement('hidden', 'courseid', $this->_customdata['courseid']);
$mform->setType('courseid', PARAM_INT);

And add the courseid in the $mform declaration in managereport.php:

$mform = new import_form(null, array('courseid'=>$course->id));

problem:
The string for the quickinfo of the helpbuttons is not found.

solution:
The Pluginame as second parameter is missing in the get_string methods here. Just add them in all add_help_button calls of the plugin.

One more issue for Moodle 2:

The layout for the showreports page should be changed from incourse to report. Otherwise in some themes the tables are cut of on the rigt side. Just change $PAGE->set_pagelayout('incourse'); to $PAGE->set_pagelayout('report'); in the viewreports.php.

Greetings
