[TYPO3] How do I get ###TCA_INPUT_module_sys_dmail_category### to work in sr_email_subscribe

[Andreas]

Hi list!

In sr_email_subscribe there is a marker in the html template named 
###TCA_INPUT_module_sys_dmail_category### that i guess is supposed to be 
substituted with a category selector. The problem is it isn't.

I have followed the documentation and have set all the necessary 
configuration values (I think).

TS constants:
plugin.tx_sremailsubscribe.module_sys_dmail_category_PIDLIST = 252
plugin.tx_sremailsubscribe.dmailCategories = 0;1;2;3
plugin.tx_sremailsubscribe.formFields = 
email,first_name,last_name,address,city,zip,static_info_country, 
module_sys_dmail_category,hidden,module_sys_dmail_html

Page TSconfig:
TCEFORM.tt_content.module_sys_dmail_category.disabled = 0
TCEFORM.tt_address.module_sys_dmail_category.disabled = 0
TCEFORM.fe_users.module_sys_dmail_category.disabled = 0
TCEFORM.sys_dmail_group.select_categories.disabled = 0
TCEFORM.tt_content.module_sys_dmail_category.PAGE_TSCONFIG_IDLIST = 252
TCEFORM.tt_address.module_sys_dmail_category.PAGE_TSCONFIG_IDLIST = 252
TCEFORM.fe_users.module_sys_dmail_category.PAGE_TSCONFIG_IDLIST = 252
TCEFORM.sys_dmail_group.select_categories.PAGE_TSCONFIG_IDLIST = 252

Page with id 252 is a sysfolder that contains direct mail categories.

System info:
Typo3 4.0, direct_mail 2.1.1, sr_email_subscribe 0.3.1, 
sr_feuser_register 2.3.3


Any help on this would be much appreciated. Has anyone made this work?
