In taglib.tld, set the value of the rtexprvalue to "true" for the
"value" attribute.

This is a problem with your taglib being contra to the spec I believe.

Attributes in tags must be completely runtime expressions, or completely
compile time.

Change

foo:mytag value="view.%= bar %"/

to

foo:mytag value="%= "view." + bar %"/

and it will work perfectly ;)

 Hello

 In ScreenDefinitions.jsp in Sun's Pet Store demo (which I haven't tried
 to run), I see:

 j2ee:Screen screen="%=ScreenNames.MAIN_SCREEN%"

 When I try to make my own taglib perform the same trick under Orion, the
 expression is not processed at all, and so my tag

 foo:mytag value="view.%= bar %"/

 receives the literal string "view.%= bar %" instead of having the
 contents of bar stuck in there.

 Is the order of processing configurable somewhere?  Can anyone suggest
 where I'm going wrong there?

  foo:mytag value="view.%= bar %"/
 
  receives the literal string "view.%= bar %" instead of having the
  contents of bar stuck in there.

 In taglib.tld, set the value of the rtexprvalue to "true" for the
 "value" attribute.

Also, try changing your tag to foo:mytag value="%= "view." + bar %"/.

I'm unsure as to where this is in the spec, but I find taglibs only seem to
recognise dynamic expressions if the entire attribute is in %= %.
