I have an embedded form with a tabset that has 5 tabs. I know that based on other posts in the old forum that a tabset can cause issues with the cam variable directives. I have worked around the saving issues for text and checkboxes based on the following. https://groups.google.com/forum/#!msg/camunda-bpm-users/Qvm-CE-7O4w/GWKA-5XVyt0J
However I have an issue where I want to have multiple file upload fields (one file upload control in each tab). How do I handle the file upload for a tabset? Is the following the best approach?
How did you handle the generation of the link to the file to allow someone to dowload? I was having trouble on load of the embedded form if the file upload process variable is not set yet.
I know there is the cam directive but it appears that only works once you have posted a file and the variable is set.
It is a known bug that the file download directive throws an exception when the file variable is not set as a variable.
A workaround is to add it nevertheless with a null value.
