Hello,
I'm building a custom wizard that allows the user uploading an XLS file and importing it into a purchase order. For users' convenience I want to provide an XLS template so they download, fill and upload it back. I'm passing the template into the wizard as a read only Binary field with its value established through the _default_get function.
The problem is that when I open the wizard, the template field is locked and can't be downloaded. The data is there, and so is the filename, but when I pass the cursor over the filename it becomes a "forbidden" (🚫) sign.
How can I fix this?
Thanks.
