Accessing 'Folder' form field

jvaidya

How do you access the entry for the Upload Folder form field in Activiti Process Services in a Script Task?

You can do this for a file with :

import com.activiti.service.runtime.RelatedContentService;
import com.activiti.service.runtime.RelatedContentStreamProvider;
import com.activiti.domain.runtime.RelatedContent;
import java.io.InputStream;
import org.apache.commons.io.IOUtils;
import java.nio.charset.StandardCharsets;
String fileVariableName = "file";
List<RelatedContent> contentList = relatedContentService.getFieldContentForProcessInstance(execution.getProcessInstanceId(), fileVariableName, 1, 0).getContent();
RelatedContent content = contentList.get(0);
out.println("GDH :" + content.getName());
execution.setVariable("file_name", content.getName());

How would I modify this to give me the path of the folder uploaded?

Thanks!

Hi Jay,

The folder information is stored as JSON String. Please check the last section of Configuring the folder entity parent | Alfresco Documentation for more details.

I just tested it and found that it is actually stored as a HashMap instead of a JSON String. Did you notice that too?

I can print the selected Folder ID using the following groovy script in a script bpmn component.

if(execution.getVariable('variablename'))
println execution.getVariable('variablename')['path']['id']

Can you please raise a defect with the documentation where it says the data is stored as JSON String which is not quite correct?

Hi Ciju.

I tried working with the JSON too and failed.

What were valid values for 'path' and 'id' in your script?

That's part of the folder value which is stored as a Map<String, Map>. Please refer Configuring the folder entity parent | Alfresco Documentation for more details.

Yes, I know this part of the documentation.

It says it's a JSON, e.g.

{"path":{"id":"47cb278d-c775-444f-a23e-b9f2d92390da","title":"documentLibrary > my-folder","folderTree":[{"id":"ec5eb0ec-76a0-4175-adbf-dcf3842ed00c","title":"documentLibrary","simpleType":"folder","folder":true},{"id":"47cb278d-c775-444f-a23e-b9f2d92390da","title":"my-folder","simpleType":"folder","folder":true}]},"

Taking this example, what are the values for path and id in your script?

path: 'documentLibrary > my-folder'

id: '47cb278d-c775-444f-a23e-b9f2d92390da'
