        Hello!!! I'm trying to update form data, using on-value-changed:

         

        <fd:field id="density" required="true">

                        <fd:label>Плотность</fd:label>

                        <fd:datatype base="decimal"/>

                        <fd:on-value-changed> 

                                       <javascript>

                                                       var value = this.value;

                                                       var test = 
cocoon.parameters["comp_id"];

                                                       var sql = "update 
compositions set density = " + value + " where id = " + test;

                                                       dao.dbi.execute(sql);

                                       </javascript>

                        </fd:on-value-changed>

          </fd:field>

         

        But as output I've got the exception:

         

        java.sql.SQLException: ORA-00904: "UNDEFINED": invalid identifier

         

        What's the problem ?

        value is probably undefined. what do you see when you try to print its 
value in the console. print('Value '+value);
