How to search DocumentPackage by attribute?

Hey Romain, What you will probably end up doing is going through your packages in draft and retrieve the attributes. Here's an example code on how to do so:

int i = 1;

Page resultPage = client.getPackageService().getPackages(new PackageStatusConverter(PackageStatus.DRAFT).toAPIPackageStatus(), new PageRequest(i, 50));
		
while (resultPage.getNumberOfElements() != 0) {
          for (DocumentPackage pack : resultPage) {
	  System.out.println(pack.getName());
          DocumentPackageAttributes attributes = pack.getAttributes();
	  Map attr = attributes.getContents();

	  for (Map.Entry entry : attr.entrySet()) {
                    System.out.println(entry.getKey() + ", " + entry.getValue());
	    }
            i++;
          }
          resultPage = client.getPackageService().getPackages(new PackageStatusConverter(PackageStatus.DRAFT).toAPIPackageStatus(), new PageRequest(i, 50));
}

Here, I used a variable "i" to keep track of the package index in the resulting page. Also, the maximum number of packages you can retrieve per page is 50. Having said this, this is an exhaustive method of searching your package attributes. This should be alright for a relatively small number of packages, but as you create more and more packages overtime, I wouldn't suggest this method. You would be better off keeping track of your attributes within your application and associate them with the package id that eSignLive returns you.
