a4j:actionparam doesn't support comma in value ---------------------------------------------- Key: RF-7604 URL: https://jira.jboss.org/jira/browse/RF-7604 Project: RichFaces Issue Type: Feature Request Components: component-a4j-core Environment: richfaces-ui-3.2.1.GA Tomcat 6.0.16 Facelets 1.1.14 Reporter: Stephen Kinser Priority: Minor I attempt to define a value that contains a comma, as follows: <a4j:actionparam name="metricName" value="Host:type=Processors,name=CPU.UserMode" assignTo="#{GraphPageBean.metricName}"/> Here's the method that I expect to be passed Host:type=Processors,name=CPU.UserMode: public void setMetricName(String metricName) { this.metricName = metricName; } setMetricName is called with a metricName value of "Host:type=Processors". I modified the value to use a '|' instead of a ',' and I got the full value of Host:type=Processors|name=CPU.UserMode.
