I put some @Conversion(), @Element(value = java.lang.Long.class) and @TypeConversion(rule = ConversionRule.COLLECTION, converter = "java.lang.Long") in my Action and it's not working better.
So I set the convertion in a properties file with : Element_idsCommerciaux=java.lang.Long and it is working, thanks Ralf. I tried to put v2.1.6 but I had a lot of trouble with EL expression (s:if test="${}", s:if test="#session...") which seemed to have changed, but I see nothing in the docs, release ntoes or migration guide, so I gave up (600 JSP to change and no time to do it) Thanks for your help. -- View this message in context: http://www.nabble.com/Random-ClassCastException-%3A-I%27m-expecting-Long%2C-Struts-gives-me-String-on-some-servers...-tp21722894p21743689.html Sent from the Struts - User mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@struts.apache.org For additional commands, e-mail: user-h...@struts.apache.org
