hi there sorry to bother you but I am having an issue with the script bellow

           <transformer class="com.norconex.importer.handler.transformer.impl.ScriptTransformer">
                    <script><![CDATA[
                    empresas = metadata.getString('empresas');
                    consorcios_UT = metadata.getString('consorcios_UT');
                    consorcios_UT = consorcios_UT.toUpperCase();
                    metadata.setString('consorcios_UT', consorcios_UT);
                    metadata.setString('empresas', empresas);
            ]]></script>
            </transformer>

after running the script I am getting and error saying that is not a 'toUpperCase()' defined:

Caused by: :3 TypeError: null has no such function "toUpperCase" at jdk.nashorn.internal.runtime.ECMAErrors.error(ECMAErrors.java:57) at jdk.nashorn.internal.runtime.ECMAErrors.typeError(ECMAErrors.java:213) at jdk.nashorn.internal.runtime.ECMAErrors.typeError(ECMAErrors.java:185) at jdk.nashorn.internal.runtime.ECMAErrors.typeError(ECMAErrors.java:172) at jdk.nashorn.internal.runtime.linker.NashornBottomLinker.linkNull(NashornBottomLinker.java:180) at jdk.nashorn.internal.runtime.linker.NashornBottomLinker.getGuardedInvocation(NashornBottomLinker.java:66) at jdk.internal.dynalink.support.CompositeGuardingDynamicLinker.getGuardedInvocation(CompositeGuardingDynamicLinker.java:124) at jdk.internal.dynalink.support.LinkerServicesImpl.getGuardedInvocation(LinkerServicesImpl.java:154) at jdk.internal.dynalink.DynamicLinker.relink(DynamicLinker.java:253) at jdk.nashorn.internal.scripts.Script$^eval_.:program(:3) at jdk.nashorn.internal.runtime.ScriptFunctionData.invoke(ScriptFunctionData.java:637) at jdk.nashorn.internal.runtime.ScriptFunction.invoke(ScriptFunction.java:494) at jdk.nashorn.internal.runtime.ScriptRuntime.apply(ScriptRuntime.java:393) at jdk.nashorn.api.scripting.NashornScriptEngine.evalImpl(NashornScriptEngine.java:418)

could you please check that for me? thanks

You try to call a function on a null value. Check for null first, or use metadata.getString('empresas', 'anyDefaultString') to make sure null is never returned. Alternatively, you can use the CharacterCaseTagger to avoid relying on scripting for this.

hi there
after working on this problem this weekend I figure it out. the problem is that the JS implementation in JAVA do not cast automatic all variables so in order to make it work I have to cast that variable that is failing.

thanks for your help angelo
