[gatein-issues] [JBoss JIRA] (GTNPORTAL-1673) make UI validation regular expressions configurable by users

make UI validation regular expressions configurable by users ------------------------------------------------------------- Key: GTNPORTAL-1673 URL: https://issues.jboss.org/browse/GTNPORTAL-1673 Project: GateIn Portal Issue Type: Feature Request Security Level: Public(Everyone can see) Reporter: Gary Hu Assignee: Chris Laprun Fix For: 3.2.0-CR01 The current exoadmin portlet uses hard coded regular expressions to validate the UI component form in multiple java files under portlet/exoadmin/src/main/java/org/exoplatform/organization/webui/component. For example, the org.exoplatform.organization.webui.component.UIGroupMembershipForm class has the following lines: addUIFormInput(new UIFormStringInput(USER_NAME, USER_NAME, null).addValidator(MandatoryValidator.class) .addValidator(ExpressionValidator.class, "^\\p{L}[\\p{L}\\d._\\-,]+$", "UIGroupMembershipForm.msg.Invalid-char")); Can we make the validation expressions configurable by users? We can still keep the current validation expressions as the default but allow the user defined expressions to override the default.
