Catalog text field size restriction

[Dmitry]

Hi,
I found a very strange behaviour of catalog module - I can't create fields bigger that TEXT field type.
Even if I change field type manually to MEDIUMTEXT in MySQL it will be reset to the TEXT when I will edit something inside that catalog item (NOT the field, for example check searchable checkbox).
I think this happened because of this in config.php...

			'longtext' => array
				(
					'typeimage'    => 'system/modules/catalog/html/longtext.gif',
					'fieldDef'     => array
						(
							'inputType' => 'textarea'
						),
					'sqlDefColumn' => "text NULL",
				),

So the questions are: How it is better to override this setting, and is it possible to add one more option at field set-up for the future releases.

Thank you in advance..
P.S.
Catalog is the great module. This is first time I met something which catalog can't handle..

Hi,
please try putting the following in your system/config/dcaconfig.php

$GLOBALS['BE_MOD']['content']['catalog']['fieldTypes']['longtext']['sqlDefColumn'] = "MEDIUMTEXT NULL";
