Hi,
(Note: I have read some threads on this list about the same topic, but I
found no answer. If I missed the right thread, I'm sorry. Furthermore,
this might be a struts- and not a tiles question. I am not sure about that.)
I am trying to figure out how to do this the "right" way:
I have a struts action which returns a tile as a result. This tile has
an attribute which points to another tile, which uses another action as
template:
<definition name="layout" template="layout.jsp" >
<put-attribute name="menu" value="menu" />
</definition>
<definition name="menu" template="/menu.action" />
layout.jsp contains the line:
<tiles:insertAttribute name="menu" />
At first I got the error message:
The requested resource (/s2demo/menu.action) is not available
(This text was printed where the menu should have gone)
Somewhere on this list I found that I should add the struts filter
dispatcher like this:
<filter>
<filter-name>struts2</filter-name>
<filter-class>...FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
<dispatcher>INCLUDE</dispatcher>
</filter-mapping>
(filter class name truncated for shortness)
After I did this, everything seemed fine at first - the menu rendered.
First question: is this the right way of doing that?
But then I started to use my function taglib. The tag library internally
uses ServletActionContext.getRequest() for accessing the
HttpServletRequest object.
As soon as layout.jsp contains <tiles:insertAttribute name="menu" />,
ServletActionContext.getRequest() returns null in my taglib
implementation, when called from layout.jsp like this:
<tiles:insertAttribute name="menu" />
<c:if test="${mylib:someThing()}" >...</c:if>
Without the insertAttribute call, the taglib works fine.
Can you help me with this?
Thanks in advance!
