Hi,

the java code:

String formula =
    xspAttr.addAttribute(
      "",
      "column",
      "column",
      "CDATA",
      "cd_formula"
    );
   

    this.contentHandler.startElement(
      "http://apache.org/cocoon/SQL/v2",
      "get-string",
      "esql:get-string",
      xspAttr
    );
    xspAttr.clear();

   

    this.contentHandler.endElement(
      "http://apache.org/cocoon/SQL/v2",
      "get-string",
      "esql:get-string"
    );

    ;



If I try to use double () like this:

String formula = ((String)<esql:get-string column="formula"/>);

I got ')' expected error, the source in this case:


String formula = ((String)
    xspAttr.addAttribute(
      "",
      "column",
      "column",
      "CDATA",
      "cd_formula"
    );
   

    this.contentHandler.startElement(
      "http://apache.org/cocoon/SQL/v2",
      "get-string",
      "esql:get-string",
      xspAttr
    );
    xspAttr.clear();

   

    this.contentHandler.endElement(
      "http://apache.org/cocoon/SQL/v2",
      "get-string",
      "esql:get-string"
    );

    );

Regards,
Gabor

Try this:

<xsp:logic>
String formula = <xsp:expr><esql:get-string column="formula"/></xsp:expr>;
</xsp:logic>
