I also played around. I put all code which does work
into actions ( and while doing this I discovered that
you can count on ActionContext only inside doExecute()
/ execute() ) - i got terrible race conditions while
trying to access action context out of getter methods
of my action. When I moved the code to doExcetutze()
those races dissappeared.
As I can see from code, there are 2 kinds of session
maps in ActionContext - vanilla HashMap while not in
servlet environment, and SessionMap which is wrapper
around real session.
>From my point of view, it would be logical in servlet
entvironment to use this session map
( and of course synchronize on it, for cases where
there 2 requests paralel - like mine with frames )
Another question:
If I specify action in jsp page, when exactly it's
executed?
I got following code in jsp
---%<----------------------
<decorator:usePage id="screen"/>
<webwork:action name="'windowManager'" id="wm"/>
<webwork:action name="'renderScreen'" id="render">
<webwork:param name="'page'" value="@screen"/>
<webwork:param
name="'URL'"><webwork:url/></webwork:param>
<webwork:param name="'windowManager'"
value="@wm/windowManager"/>
<!-- foo bar -->
</webwork:action>
<webwork:if test="@render/refreshSidebar">
<SCRIPT language="JavaScript">
<!--
parent.navbar.location.href = "<%=
request.getContextPath() + "/layout/sidebar.jsp"%>" ;
//-->
</SCRIPT>
</webwork:if>
<webwork:if test="@render/refreshToolbar">
<SCRIPT language="JavaScript">
<!--
parent.parent.toolbar.location.href = "<%=
request.getContextPath() + "/layout/toolbar.jsp"%>" ;
//-->
</SCRIPT>
</webwork:if>

that windwManager is executing, but not renderScreen.
Though values were set and get on render screen...
