    Description

      Situation:
      Many Bars can be assigned to one Foo

      Models:
      Foo
      -Long id
      -String fooName
      -Set<Bar> bars

      Bar
      -Long id
      -String barName

      Action:
      FooAction
      -Foo foo;
      -List<Bar> barList

      In prepare()-method:
      barList=barService.getBarsByFilter(null) <-- Returns List

      {(1,bar1),(2,null),(3,bar3),etc.}

      list()-method just returns SUCCESS

      in result-jsp for http://localhost:8080/BarApp/Foo/list.action:

      <s:form ...
      [...]
      <tr>
      <s:checkboxlist key="foo.bars" list="barList" listKey="id" listValue="barName" name="bars" />
      </tr>
      [...]
      </s:form>

      Bug:

      When the 2nd checkbox (the one with 'null' in name-property) is created, the freemarker-template throws an error (see message below) and building of the page stops.

      Error thrown:

      FreeMarker template error!

      Error on line 33, column 13 in template/simple/checkboxlist.ftl
      stack.findString(parameters.listValue) is undefined.
      It cannot be assigned to itemValue
      The problematic instruction:
      ----------
      ==> assignment: itemValue=stack.findString(parameters.listValue) [on line 33, column 13 in template/simple/checkboxlist.ftl]
      in user-directive s.iterator [on line 25, column 5 in template/simple/checkboxlist.ftl]
      in include "/${parameters.templateDir}/simple/checkboxlist.ftl" [on line 2, column 1 in template/synaix_xhtml/checkboxlist.ftl]
      ----------

      Java backtrace for programmers:
