I have been working for years with OpenClinica 3.1 (PostgreSQL 8.4, tomcat 6.0.32).
Now we have just installed a new openclinica server, OpenClinica 3.11 (PostgreSQL 9.3, tomcat 7.0.52)
In this new server, many validation expressions of the items are not working. Same validations (CRF) are working in the oc 3.11 server.
After analysing we have found out that the validation does not work when it includes a regular expression using the scape character '\'.
For example, this validation:
does not accept a value of 2001-01, openclinica shows the validation error message.
Can anyone help to fix this problem.
