[ https://issues.jboss.org/browse/JBIDE-15937?page=com.atlassian.jira.plugi... ] Martin Malina commented on JBIDE-15937: --------------------------------------- OK, now I get why it happens (probably) - the seam runtimes are all effectively default (unless you have two or more of the same version). I agree, it would be better to ensure they stay checked, but I'm not sure how to handle this - maybe take the approach of Installed JREs? When you uncheck the default JRE, you get an error message that at least one has to be selected (in this case we would need to add "of this version"). -- This message is automatically generated by JIRA.
