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.

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. musachy walidito wrote: I don't hink I'm adding anything.

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.

I think you should take a look at the Struts2/Webwork tutorials http://www.opensymphony.com/webwork/wikidocs/Tutorial.html and http://struts.apache.org/2.x/docs/tutorials.html If you look at the showcase code you will see this for the AjaxTest action: in struts-ajax.xml: action name=AjaxTest class=org.apache.struts2.showcase.ajax.AjaxTestAction result/ajax/AjaxResult.jsp/result /action in AjaxTestAction.java: public class AjaxTestAction implements Action, Serializable { private static int counter = 0; private String data; public long getServerTime() { return System.currentTimeMillis(); } public int getCount() { return ++counter; } public String getData() { return data; } public void setData(String data) { this.data = data; } public String execute() throws Exception { return SUCCESS; } } and AjaxResult.jsp: %@ taglib prefix=s uri=/struts-tags % % request.setAttribute(decorator, none); response.setHeader(Cache-Control,no-cache); //HTTP 1.1 response.setHeader(Pragma,no-cache); //HTTP 1.0 response.setDateHeader (Expires, 0); //prevents caching at the proxy server % Result: s:property value=count/ @ s:property value=serverTime/ br/ s:property value=data/ musachy walidito wrote: I, I wanna run this type of example app : http://www.planetstruts.org/struts2-showcase/viewSource.action?page=/ajax/remotediv/example1.jsp : s:div 13: id=once 14: theme=ajax 15: cssStyle=border: 1px solid yellow; 16: href=/AjaxTest.action 17: delay=5000 18: loadingText=loading... 19: Initial Content /s:div In other word, a basic ajax component that allows a refreshment of only a part of my page.
