This is the way, but if credentials is 'null' or the property is not called getGetUserName you will get this 'error'. Keep in mind that EL uses the 'beans' standard, so most likely  ${credentials.userName} is what you need

Hi ronald,

Thanks for the reply.I have even tried ${credentials.userName} too, but still got the same error. But i achieved it by using selectOneMenu item.Here i have achieved by  following code.



<hutputText value="Assignee" />
<h:selectOneMenu value="#{processVariables['manager']}">
<f:selectItem value="#{incidentCO.managerName}"  />
</h:selectOneMenu>

where i assign the value to a processVariable named manager and in the i have assigned  ${manager} in the diagram property. Still i need some mechanism so that process variable itself hold the value directly without assigning the value to it.


Thanks
