when i click start the faram set the process_id in the url but not in the backing bean "processList"
the set method is not invoked

The code source of the bean

package beans;

import java.util.List;

import javax.enterprise.inject.Produces;
import javax.inject.Inject;
import javax.inject.Named;

import org.activiti.engine.RepositoryService;

@RequestScoped
public class ProcessList {
  
  private String processDefinitionKey; 

  @Inject
  private RepositoryService repositoryService;

&nbsp; public List<ProcessDefinition> getProcessDefinitionList() {
&nbsp;&nbsp;&nbsp; return repositoryService.createProcessDefinitionQuery()
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; .list();
&nbsp; }
&nbsp; 
&nbsp; public void setProcessDefinitionKey(String processDefinitionKey) {
&nbsp;&nbsp;&nbsp;System.out.println("settttt_________" +processDefinitionKey);
&nbsp;&nbsp;&nbsp; this.processDefinitionKey = processDefinitionKey;

It's rather JSF question than Activiti. You've set request param then use bean instead ? Use param on second page or change bean to some other scope.
