find the answer

JDatabaseQuery is now abstract due of the work done to support new
database engines (Windows Azure and Microsoft SQL Server). This means
you must use $db->getQuery(true); to instantiate a query as is the
correct practice in Joomla 1.6.

The correct, advertised way to use JDatabaseQuery in 1.6 was:

$db = JFactory::getDbo();
$query = $db->getQuery(true);

The following incorrect practice will no longer work in 1.7.

$db = JFactory::getDbo();
$query = new JDatabaseQuery;

Developers of 1.6 extensions are advised to upgrade their code
immediately to the correct format (which will work fine in both Joomla
1.6 and 1.7).

I’m not sure why this is marked as a solved problem!

There is still an issue with Joomla 1.7 and JA Rave as shipped.

Is there a particular file that one can edit to implement the recommended code fix?

This is not solved because JA have not yet released their templates as J1.7 compatible. Please do not upgrade until they are released.

There will likely be a lot of folks updating since a Joomla security alert went out a couple of days ago recommending an immediate update to 1.7 to fix a security issue.

Personally I think that alert is extremely unfair thing for the Joomla team to have done. They should be fixing J1.6.x rather than trying to force the update to J1.7 so quickly. IMHO it is very unfair on all the extension developers, especially the ones who do it as a hobby, out there to be forced to update their work at the drop of a hat.

It is especially wrong in my mind as by not fixing their problem Joomla.org are effectively ending their support for their own project 1 month early.

Edit plugins/system/jat3/jat3/core/joomla/modulehelper.php and replace line 292 with “$query = $db->getQuery(true);”

This seems to fix the issue for me.
