When SSO is enabled, multipart form and form enconding stop working. -------------------------------------------------------------------- Key: ELY-1525 URL: https://issues.redhat.com/browse/ELY-1525 Project: WildFly Elytron Issue Type: Bug Affects Versions: 1.1.6.Final, 1.2.1.Final Reporter: Estevão Góes Priority: Critical Attachments: 0001-ELY-1525-Initialize-FormParserFactory-with-FormEncod.patch, ely-1515-reproducer.zip I developed a JSF application with "h:inputFile" component and it requires a form with " enctype="multipart/form-data" ". I use this tutorial for SSO: https://docs.jboss.org/author/display/WFLY/Web+Single+Sign-On . When I execute the last step: " /subsystem=undertow/application-security-domain=other/setting=single-sign-on:add(key-store=example-keystore, key-alias=localhost, domain=localhost, credential-reference=clear-text=secret}) ", all commandButtons stop working. If I remove the "h:inputFile" component and " enctype="multipart/form-data" " from form all buttons works again, but all words with accents are corrupted.
