Dear Tecnoteca,
in openMAINT-2.1_cmdbuild 3.3.1, I created a test process, with no attributes but the default Code and Description.
Then, in TWE I created a process with just three Human Tasks in sequence:
-
Start(empty) -
Attachments Manager(with just one openAttachment widget) -
Verify attachments(empty)
When I run an instance of this process and go to the “Attachment Manager” step I use the button to open the attachments window, but when I try to upload a new document I receive the following message in the “generic error” popup:
“java.lang.NumberFormatException: Illegal embedded sign character”
I tried with PDF files, but the issue is present with other formats too, even with common text files.
I can then “Execute” this step, and the process stops to the last one “Verify attachments”, where I can confirm in the attachments tab that the document was correctly uploaded.
What may be the root cause of the Java Exception?
Following is the content of the cmdbuild_req.log file, in case it may help:
