[esql] xsp:logic doesn't work inside ?

[Christina]

I tried to use if () inside <esql:query> like this: .... <esql:query>     <xsp:logic>             if (true) {                 <esql:parameter>...</esql:parameter>             }     </xsp:logic> </esql:query> .... but every time there is error message on this "if", it is ok if I delete everything before and after the nested <xsp:logic> tag. So <xsp:logic> cannot work inside of <esql:query>? or I did something wrong? Thanks!
