For the moment I've tried to put a success return in my action ( is it

If I only put a success-type result, It creates an infinite loop (always
displays loading).

Re: Still Ajax and Struts 2
You are seeing that error in your server logs right? There's a couple of
things that we still need to fix for this integration between Struts and
Dojo, but the application should work anyway.

Re: Still Ajax and Struts 2
Hi,
Actually, I get this error both in my eclipse console and in my web page
(debug enabled).
First of all here is the jsp code that I use:
s:div
id=reportDivId
cssStyle=border: 2px solid red;
href=/AjaxTestAction.do
theme=ajax
delay=3000
errorText=There was an error
loadingText=loading...
s:property value=count/ @ s:property value=serverTime/
br/
/s:div
this is the redundant error that I get on my eclipse console :
-SEVERE: Error setting expr 'dojo.transport' with value
'[Ljava.lang.String;@e8f27e'
ognl.OgnlException: target is null for setProperty(null, transport,
[Ljava.lang.String;@e8f27e)
at ognl.OgnlRuntime.setProperty(OgnlRuntime.java:1624)
at ognl.ASTProperty.setValueBody(ASTProperty.java:105)
at ognl.SimpleNode.evaluateSetValueBody(SimpleNode.java:177)
...
and after a first call of the action I get this on my browser :
DEBUG: widget ID collision on ID: reportDivId
...
I think this must come from the fact that with my code, I want (for the
moment) that the action is called only once, but in fact after the 3000 ms
delay, the action is called again, and it returns a success to the same
div id=reportDivId ..., that's why there is a collision. Isn't it?
If so, what it is the way to make sure that my div tag doesn't recall my
action more than once ?
Moreover, how come th samples of the Showcase does NOTprovide the
corresponding action and struts.xml files. Because it works on the showcase,
so with the right code it should work at home
thanks.

In other word, a basic ajax component that allows a refreshment of
only
a
part of my page.
But I didn't get how to write the corresonding action and action
mapping.
For the moment I've tried to put a success return in my action ( is
it
enough ?), but I don't see what to put in my action mapping (i mean
inside
the action name=blablabla ... tag. If I put nothing, of course
it's
wrong.
Re: Still Ajax and Struts 2
I don't hink I'm adding anything.
Here is my code :
the action :
public String execute() throws Exception
{
return SUCCESS;
}
the struts.xml:
action name=AjaxTestAction
class=dashboard.actions.AjaxTestAction
result/JSPs/Menu.jsp/result
/action
and the jsp :
head
...
s:head theme=ajax debug=false/
...
/head
body
s:div
id=once
cssStyle=border: 2px solid red;
href=%{ajaxTest}
theme=ajax
hhookayy
/s:div
/body
I know it's working on the shwocase, but my app is not working... Since the
showcase action and struts sources are not available...
What I see on my screen is the top of jsp that is written twice, in fact,
the top html is loaded once (normal), but after the action call, the top is
written another time, I don't know why... Moreover, the eclipse console
displays the same error (dojo.transport) again and again...

Moreover, how come th samples of the Showcase does NOTprovide the

so with the right code it should work at home

Re: Still Ajax and Struts 2
What is happening is that there is an error on the request, probably the
action mapping is wrong, and it is returning a page with the error, but
that page has the same menu as showcase, that's why your are seeing it
twice. Put the full url for the action on the address bar, after you get
that to show the right page (what you expect to see in the div tag),
then try the div.

Re: Still Ajax and Struts 2
Ok thank you very much that works !
My mistake was in the mapping, where I redirected to the same jsp as the one
where I've putted the div tag.
Actually, I had to write a simple jsp in ordrer that it works.
Otherwise,
I'm always having the error message on my console :
SEVERE: Error setting expr 'dojo.transport' with value
'[Ljava.lang.String;@9de832'
ognl.OgnlException: target is null for setProperty(null, transport,
[Ljava.lang.String;@9de832)
at ognl.OgnlRuntime.setProperty(OgnlRuntime.java:1624)
wich is repeated till the infinite when I choose to refresh my div ajax
component. Can this be dangerous in term of performance, etc ?
thanks.
