Don Brown updated WW-1887:
--------------------------
Fix Version/s: 2.0.9
> struts 2.0.7 template/simple/select.ftl error/fix
> -------------------------------------------------
>
> Key: WW-1887
> URL: https://issues.apache.org/struts/browse/WW-1887
> Project: Struts 2
> Issue Type: Bug
> Reporter: Jason Thurston
> Fix For: 2.0.9
>
>
> To fix I extracted template/simple/select.ftl from the struts2-core-2.0.7.jar
> to WEB-INF/classes/template/simple/select.ftl
> I then
> changed line 60 from:
> <option value="${itemKey?html}"<#rt/>
> to:
> <option value="${itemKeyStr?html}"<#rt/>
> and I inserted the following line before line 60:
> <#assign itemKeyStr=itemKey.toString() />
> I got the idea from another .ftl file that does something similar.
> The error message this fixed was:
> Error on line 60, column 22 in template/simple/select.ftl
> Expecting a string, date or number here, Expression itemKey is instead a
> freemarker.ext.beans.BooleanModel
> The problematic instruction:
> ----------
> ==> ${itemKey?html} [on line 60, column 20 in template/simple/select.ftl]
> in user-directive s.iterator [on line 41, column 1 in
> template/simple/select.ftl]
> ----------
> Java backtrace for programmers:
> ----------
> freemarker.core.NonStringException: Error on line 60, column 22 in
> template/simple/select.ftl
> Expecting a string, date or number here, Expression itemKey is instead a
> freemarker.ext.beans.BooleanModel
