java - JSF show a p:dialog if a parameter is true -

so want quit simple. have page displays list of users, example adminusers.jsf, , has list of users. click new user button , modal p:dialog shows user form.

this works perfect want allowing users click on link , adminusers.jsf shows p:dialog enabled.

so if users goes url

http://localhost:8080/pages/adminuser.jsf?create=true 

the modal dialog shown without clicking button. thought of way of doing maybe not proper jsf way. thinking. capture "create" on useradmincontroller, , set

<h:outputtext/> 

write javascript call userpanel.show, param this.

rendered="#{usuarioadmincontroller.create}" 

is correct way of doing this.

you can bind value request parameter directly visible attribute of dialog this:

<p:dialog visible="#{param.create}"/>
