I’ve tried to make a simple account template with a plain textbox and an option to add attachtments. When there is more than a few lines of text with a couple of enters, I get something weird in my export.
This error in export can indeed occur in case your input text contains some enters. This can easily be resolved by putting the input field between ‘ic’-tags (so the field only displays in input) and by putting the content between ‘nic’-tags (so the content is displayed in export). Make sure you also use the ‘multiline_table’ when printing the content.
