1. ELException when trying to login at the DARIAH IdP

Issue: When trying to login at the DARIAH IdP, the following error occurs:

org.springframework.binding.expression.EvaluationException: An ELException occurred getting the value for expression 'authenticationContext.setAttemptedFlow(thisFlow)' on context [class org.springframework.webflow.engine.impl.RequestControlContextImpl]

Explanation: This is a known issue with the Shibboleth IdP software, the DARIAH IdP is based on. We reported this issue in April 2017 and currenctly there is an open bug regarding this error (cf. https://issues.shibboleth.net/jira/projects/IDP/issues/IDP-1163).

Workaround: Until this bug is fixed, the only solution is to reload the page. Since this error happens very rarely, it should be possible to login properly now.
