[jbossseam-issues] [JBoss JIRA] Resolved: (JBSEAM-3535) don't add parameter to Url if value is null

don't add parameter to Url if value is null ------------------------------------------- Key: JBSEAM-3535 URL: https://jira.jboss.org/jira/browse/JBSEAM-3535 Project: Seam Issue Type: Feature Request Components: JSF Controls Affects Versions: 2.1.0.CR1 Reporter: Dan Allen Assignee: Dan Allen Fix For: 2.1.0.GA Attachments: JBSEAM-3535.txt Original Estimate: 15 minutes Remaining Estimate: 15 minutes When the value of a parameter declared inside of a Seam UI command control using <f:param> is null, then it should not be appended to the URL. Currently, it is appended with a blank value. The problem is that there is a difference between an empty string (blank value) and not being present. Additionally, by setting the value to null (or leaving off the value attribute), it provides a way to suppress a parameter from being added the URL. Assuming the link was defined as follows: <s:link view="/UserEdit.xhtml"> <f:param name="userId"/> </s:link> The URL should be: /UserEdit.seam This might override a page parameter for instance.
