[TYPO3-shop] [Typo3-shop] Problem extending tt_products

[K. Zugberg]

Hello Franz,

thanks for your answer. I followed your advice and did the following:

I added a file named ext_localconf.php to my extension and inserted the 
code shown below (Initially there was no ext_localconf.php because I 
created the extension with the kickstarter)
The extension itself has a file named ext_tables.php where the functions 
loadTCA, addTCAcolumns and addToAllTCAtypes are called in order to 
extend tt_products.
When debugging I can see that the ext_localconf.php of my extension is 
loaded.
Nevertheless I can not see the new fields added by my extension in the 
backend form for editing products. Do you have any idea what might be 
wrong? Have I forgotten something? Do I need to use a hook to display 
the fields in the backend form?

Greetings

Katharina Zugberg
