Copying and appending physical files

Happy to report the problem is solved. The method did already copy the file but failed to append it to the Document item, so all I had to do was create that relationship item. I also added a check at the beginning of the code so I don't accidentally overwrite any existing file. This method is now fired on the onAfterAdd and onAfterUpdate events. //Description: If the document item is based on a template, copy the base file and append it to the Document item Item thisItem = this; Innovator inn = thisItem.getInnovator(); string thisItemId = thisItem.getID(); string templateId = thisItem.getProperty("from_template", ""); //First check if the Document item doesn't already have an Office file attached string aml = "<AML><Item action='get' type='Document File'><source_id>" + thisItemId + "</source_id></Item></AML>"; Item alreadyHasAFile = inn.applyAML(aml); //If a relationship item was found, skip the rest of the method if (!alreadyHasAFile.isError()){ return thisItem; } //If item is not based on a template skip this entire method if (templateId.Equals("")){ return thisItem; } //Get the relationship item pointing to the template file aml = "<AML><Item action='get' type='Document File'><source_id>" + templateId + "</source_id></Item></AML>"; Item officeFileItem = inn.applyAML(aml); if(officeFileItem.isError()){ return thisItem; } //Get the file ID string fileId = officeFileItem.getProperty("related_id"); Item templateFile = inn.getItemById("File", fileId); //Recycle the old filename for the new one string fileName = templateFile.getProperty("filename"); // Item myFile = inn.newItem("File","copyAsNew"); myFile.setAttribute("id", fileId); myFile.setAttribute("useInputProperties", "1"); myFile.setProperty("filename", fileName); myFile = myFile.apply(); string newFileId = myFile.getID(); aml = "<AML><Item action='add' type='Document File' ><source_id>" + thisItemId + "</source_id><related_id>" + newFileId + "</related_id></Item></AML>"; Item newRelItem = inn.applyAML(aml); return thisItem;
