Hi

I have requirement to concatenate string in el expression . e.q. 

If  amount is >0 the  it should display Name : first name last name ( where first name = XXX, last name = YYY)

Name : XXX YYY

else

Name :

I tried to form below el but that is not working.  What should be the correct el for this case?

<af:outputText value="#{bindings.amount ge '0' ? Bundle['Label.Name'] : (bindings.FirstName) ((bindings.lastName)  : Bundle['Label.Name']}"

                                 id="ot1"/>

Thanks
