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.
