Re: XSP+logic 2nd

the produced java-File would help more to find the error but I think this will not work!
<xsp:expr>
String Prova;
</xsp:expr>


should
<xsp:logic>
String Prova="";
</xsp:logic>
somewhere before the expression and then

<xsp:expr>Prova</xsp:expr>

Could be a Bug? Re: XSP+logic 2nd

Posted by marco scotoni <ms...@gruppotrafomec.com>.
Hi, i notice that i get an error if i put <xsp:expr> between tags <esql:results>,

it seems a strange thing...there's a particular tag or method to process a result after a query?

or that's a bug?
