Re: Use of OGNL expression to access request headers

[Nicolas LE BAS <ma...@nlebas.net>]

Sorry about the delay, I've been out of the net for some time.


I think tiles uses the singular form to access the map of headers.

How about:
<put-attribute name="test"
expression="OGNL:header['x-requested-with']"  cascade="true"/>

Hope this helps,
Nick

Basically, I would like to change the extends of a screen depending if there is a header in the request with name "x-requested-with" and the value is "XMLHttpRequest". Is it possible to do that? I've tried to do a simple example with an attribute:

I haven't found any documentation on how the OGNL expressions works on Tiles, so I'm working based on how I would do it with Struts. But it doesn't seem to work. Can somebody help me?
