On ActivityStream or Activities, I want to change the field type of "data" to varchar.
I've tried on custom/Extension/modules/ActivityStream/Ext/Vardefs/nativefield_data.php and on custom/Extension/modules/Activities/Ext/Vardefs/nativefield_data.php
with the contents: $dictionary['Activity']['fields']['data']['type']='varchar';
Also tried changing it to $dictionary['ActivityStream']['fields']['data']['type']='varchar'; Still doesn't work.
Can anyone help change the data type of a field in ActivityStream / Activities?
