• Child elements:

Basic upload example

• Upload a new document to a folder.

• folderUuid is a valid folder uuid. You can also use folderPath and set a path, which is more human readable.

Document update

• Create a new version of a given document.
• documentUuid is the UUID of the document to be replaced.
• Note the type parameter which is set to update.

  </workflow-form>
</workflow-forms>

Upload example with dynamic parameters

• Upload a document into a non-predefined folder.
• data is a valid mapping variable. This variable is used to dynamically set folderPath attribute.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE workflow-forms PUBLIC "-//OpenKM//DTD Workflow Forms 2.6//EN"
                                "http://www.openkm.com/dtd/workflow-forms-2.6.dtd">
<workflow-forms>
  <workflow-form task="upload test">
    <upload name="upload" label="Upload document" data="updData" />
  </workflow-form>
</workflow-forms>

This is the Java code which set the data and should be executed before the task which displays the form element:

import org.jbpm.graph.def.ActionHandler;
import org.jbpm.graph.exe.ExecutionContext;

import com.openkm.bean.form.Upload;

public class UploadAction implements ActionHandler {
    private static final long serialVersionUID = 1L;

    @Override
    public void execute(ExecutionContext ctx) throws Exception {
        Upload upd = new Upload();
        upd.setFolderPath("/okm:root/dstFld");
        ctx.setVariable("updData", upd);

        // Go to next node
        ctx.getToken().signal();
    }
}
