CDK server adapter can be saved even though that there is error --------------------------------------------------------------- Key: JBIDE-25351 URL: https://issues.jboss.org/browse/JBIDE-25351 Project: Tools (JBoss Tools) Issue Type: Bug Components: cdk Affects Versions: 4.5.1.Final Reporter: Ondrej Dockal Assignee: Rob Stryker Fix For: 4.5.2.Final CDK 3.2+ server editor allows user to save the editor even if it shows error in server's name that is already in use. Also, error decorator is placed in the bottom part of the field, and in page header, there is only message "1 error detected". Change the error message in header or just do not show anything as is happening with validation of field like Minishift Binary.
