Transformer Failing

[Tyree731]

Hi. I have a transformer set up so that when an ORU^RO1 message with OBX Observation Results segments filled with an RTF file come in, I write out the contained RTF file. All RTF parts map to the path "msg['ORU_R01.PATIENT_RESULT']['ORU_R01.ORDER_OBSERVATION']['ORU_R01.OBSERVATION']['OBX']['OBX.5']", so I index them as I would an array. Being that the path is an array, I use the .length property of the array to know how long the for loop should go. It ends up looking like this-

------------------------
var RTF = "";
var Array_Length = msg['ORU_R01.PATIENT_RESULT']['ORU_R01.ORDER_OBSERVATION']['ORU_R01.OBSERVATION']['OBX']['OBX.5'].length
for (var i = 0; i < Array_Length; i++) {
RTF = RTF + msg[&#039;ORU_R01.PATIENT_RESULT&#039;][&#039;ORU_R01.ORDER_OBSERVATION&#039;][&#039;ORU_R01.OBSERVATION&#039;][&#039;OBX&#039;][&#039;OBX.5&#039;][i].toString();
}

globalMap.put("RTF_File",RTF);
----------------------

Which I see no fault in assuming I&#039;m allowed to program Javascript inside of a Transformer step. However, I get the following error message when deploying-

I&#039;ve taken out the transformer step and it worked without problems. Is there something wrong with what I&#039;m doing? Do I need to put each line in its own Transformer Step? Am I allowed to declare variables in a Transformer Step? Do I need the globalMap.put command or do I just declare a variable RTF_File and it does it for me? I just don&#039;t know what I&#039;m allowed and not allowed to do.

Re: Transformer Failing

- Be sure the transformer step you&#039;re using is &#039;JavaScript&#039; type, not Mapper/MessageBuilder

- You can use the &#039;Validate Javascript&#039; button in the left, previous of publishing the channel.

Re: Transformer Failing

Thanks Alberto, hadn&#039;t realized that there was more than one type of transformer.

Re: Transformer Failing

How do you specify the transformer type ?

When I select "Add Step" in the "Edit Transformer", I don&#039;t see any way of specifying it.

Re: Transformer Failing

When you do "Add Step", you see a row with "newVar0" under column "Name" and "Mapper" under column "Type". Double click under "Type" it should show a list box with "Mapper" and "JavaScript" dropdown. Select "JavaScript".
