TOPIC: 2.7b experience log

Ok, I'm tired of creating tickets and filling captcha and etc. again and again.
For admin it's easier to monitor all in one log than jumping from one ticket to another. It will also prevent duplicating reports.

I'm going to report my experience of using 2.7b here.

I have uninstalled the 2.7b without deleting mysql rows.

After installing 2.7b I got the following message
===============================
With DT Register, you can take online registrations for your event and collect a registration fee through various payment gateways. Fully integrated calendar is included.
Can't DROP 'PRIMARY'; check that column/key exists SQL=ALTER TABLE `jos_dtregister_group_event` DROP PRIMARY KEY

DT Register component Installed Successfully!
===============================

Is this message suppose to be or I need to delete all my rows in phpmyadmin associated with DTR prior to the new installation?

----
All the events, created in 2.7a is absent in 2.7b

Creating new event with the same name I had in the uninstalled 2.7a

caused the error
Warning: Invalid argument supplied for foreach() in /home/alexey/public_html/ohmygod/administrator/components/com_dtregister/models/event.php on line 1407

==============
However the events are created in the list
The records I had for those events are visible in the backend, but without names of the registrants and information about them. Of the frontend I can't see numbers of registered users in the associated field
=====

same problems persist from 2.7a to 2.7b.

issues:

Radio buttons don't appear for "no" option in custom question fields.

frontend: registration submission produces a blank screen.

backend: no records stored for registrations. All previous event registrations have been lost.

Rollback to 2.6 does not restore entries and creates sql errors when attempting to register on front end.

registration details for existing events are still in the sql database but not being displayed by DTRegister.

Also, during install I get the following error but it says the component installed successfully:

JInstaller::install: File '/home/webadmin/elrig.org/html/tmp/install_4ceb907ad2ba5/language/fi-FI.com_dtregister.ini' does not exist.

----
After adding 2 items in the cart and proceeding to the checkout one of the item has no price and payment method in the backend
In user frontend CP the status of one of them is marked as "paid" despite I choose "paylater" for both of them

My fault, sorry. it;s ok
