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.
