Reported in this thread:
http://dspace.2283337.n4.nabble.com/Publication-Date-Metadata-td4673384.html
This issue seems to occur in the following scenario:
* You are using DSpace 4 with JSPUI
* You have re-enabled the "Initial Questions" step in the submission forms
* You have enabled one or more Workflow approval steps on the Collection
To reproduce:
1) Submit an Item to the Workflow-enabled Collection and leave the "The item has been published or publicly distributed before" UNCHECKED. Complete the submission. Behind the scenes, dc.date.issued has been temporarily set to the literal string "today" (see
DS-1745
)
2) Once the submission is completed it will head into Workflow approval. Claim the task, and you'll see an error like this:
-- Method: POST
-- Parameters were:
-- submit_claim: "Take Task"
-- workflow_id: "186"
-- step: "0"

The problem seems to be that the JSPUI is attempting to display the 'dc.date.issued' value as a DCDate...however, it was temporarily set to the literal string "today", which is NOT a valid DCDate. The error occurs here:
https://github.com/DSpace/DSpace/blob/master/dspace-jspui/src/main/java/org/dspace/app/webui/jsptag/ItemTag.java#L541
There's one of two ways to fix this:
Option #1 - Change the "Initial Questions" to actually set today's date, instead of the literal string "today". See: https://github.com/DSpace/DSpace/blob/master/dspace-api/src/main/java/org/dspace/submit/step/InitialQuestionsStep.java#L227
Option #2 - Change the JSPUI ItemTag to have a special case if 'dc.date.issued' is set to "today".
This bug does NOT occur in the XMLUI,
