Hi,

I use Seam 2.0.1GA and I found out an incorrect tip in the Seam security chapter: UI security.

I tried using: 

<h:commandButton value="Create Rel Pkg" rendered="#{s.hasRole('USER')}"
					action="#{packageAdminAction.startCreateReleasePackage}" />

but it always evaluated to false. So I changed it to: 

<<h:commandButton value="Create Rel Pkg" rendered="#{identity.hasRole('USER')}"
					action="#{packageAdminAction.startCreateReleasePackage}" />

and now it works.

Can someone please confirm this is a bug? The s.hasRole expression is properly processed in @Restrict annotation on component security.

I suggest that the UI usage be made consistent with component security @Restrict usage.

Thanks, -Guillaume

Documentation: 

s:hasRole(

Your code: 

s.hasRole(

Does that answer your question?

D'oh, thanks for seeing the obvious. works great with s:hasRole

Now comes the next question, I didn't know you could use semi-colon notation in an EL expression, can somebody tell me what makes it different from the regular dot (.) notation ?

It's often good to know why things are such a way in order to remember it.

Thanks, -Guillaume

I don't think a colon has any special meaning in normal EL but Seam has an own EL-resolver so they are free to use whatever they like. It is probably needed anyway in order to separate it from a normal EL-resolve involving an variable named s.

 

If a man speaks in the forest and there is no woman around to hear him, is he still wrong?
