Duplicate name exists when using transformDocument() function

mrmjlee

Hi all,

I am trying to use the transformDocument function to convert a text file into a pdf file.

I have a custom content type (text file) with a custom action - this action calls the custom web script to convert to pdf.

For one time transformation , it works fine. However, if I modify content in the same file then try to convert this into pdf, it raises the duplicate name error.

In the custom webscript file:

var nodeRef = utils.getNodeFromString(args["nodeRef"]);

var newPdf = nodeRef.transformDocument("application/pdf");

model.pdfNodeRef = newPdf;

I tried exception handlings to catch this error.

I also tried to add the version name to newPdf node.

Could anyone give me some suggestions please?

Please note that I am working on Alfresco 5.1.1

Thank you

Hi MJ,

you get this error because there is already a pdf with the same name. It won't be replaced automatically - so you have to remove the pdf version of your document before creating a new one.

var node = utils.getNodeFromString(args["nodeRef"]);
var pdfName=node.name.replace(/\.+?$/,".pdf"); //Replace the extenison of node.name with ".pdf"
var pdfNode=node.parent.childByNamePath(pdfName); 
if (pdfNode !== null) { pdfNode.remove()}; //if pdf is existing, delete it
var newPdf = node.transformDocument("application/pdf");
model.pdfNodeRef = newPdf;‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Not tested - hope it works,

Martin

Thank you Martin,

I've tried your code and it came up with two errors.

There was an error "Ambiguous calling to String.replace function" so i used (node.name+ "") instead.

Another issue I am having trouble is that now the code cannot find the node info. The log shows 'Node does not exist' even for the first conversion of pdf documnet. I think the 'node.parent.childByNamePath' is the one which causes this issue.

Could give me an advice please?

Thank you

Hi MJ,

(node.name+"") is right, and the second problem is just because the line to build the pdf name seems not to work:

var pdfName=node.name.replace(/\.+?$/,".pdf");‍‍

replace it with

var pdfName=(node.name+"").substr(0,name.lastIndexOf("."))+".pdf";‍‍‍

should work now. 🙂

Thank you for your support Martin,

I still see the following SAME error when I try to create another pdf document of the same txt file:

Caused by: org.springframework.dao.DuplicateKeyException:

Maybe the these lines are not executed properly before the transformDocument function

var pdfNode=node.parent.childByNamePath(pdfName); 
if (pdfNode !== null) { pdfNode.remove()}; //if pdf is existing, delete it

Or it might be due to the custom associations I use in the original text file?

Thank you
