Content update problem: url is unmodified

Hi to everyone, I've a strange problem.First I introduce briefly what I'm trying to do:I'm trying to create a tool so that a workflow could write its history into its package documents (open offcice). To do this, i have a 'javascript' action (that is, a BaseProcessorExtension mapped into a javascrip

I found something interesting. If I save the document (using the custom action: script) I have the same behavior of the workflow.

Looking into the ScriptNode class, I also found something interesting: in method setContent(String) the operations are apparently the same as I followed, but at the end of the method we have:


writer.putContent(content.getInputStream());
// update cached variables after putContent()
this.contentData = (ContentData) services.getNodeService().getProperty(nodeRef, this.property);
‍‍‍‍‍

Is it possible that I write the 'good' url into the Node but not on the ScriptNode using the writer.putContent (since I see it is explicitly set in ScriptNode), and then at the end of the Workflow task we have a sort of autosave on the ScriptNode that is overwriting the contentUrl with the old one?

Ok, the analysis was right: the ScripNode didn't update automatically the contentUrl property, so doing manually worked. Here is the complete code:

        File tempFromFile = TempFileProvider.createTempFile("OpenOfficeContentFiller-source-", ".odt");
        File tempToFile = TempFileProvider.createTempFile("OpenOfficeContentFiller-target-", ".odt");
        
        // download the content from the source reader
        reader.getContent(tempFromFile);

        InputStream is = new FileInputStream(tempFromFile);
        
        ZippedDocumentTemplate zippedDocumentTemplate = new ZippedDocumentTemplate(is);

        OutputStream os = new FileOutputStream(tempToFile);
        
        zippedDocumentTemplate.createDocument(m, os);

        os.close();
        InputStream is2 = new FileInputStream(tempToFile);
        
        ScriptContentData contentData = (ScriptContentData)destinationNode.getProperties().get(ContentModel.PROP_CONTENT);
        contentData.write(is2);
