When I download folders as zip which type is not cm:folder I get empty zip archive. For folders with cm:content type and for documents it works properly.More details:In our project we have created a custom folder type with parent cm:folder:
<type name="ef:folder">
<title>Parent of all folders</title>
<parent>cm:folder</parent>
<mandatory-aspects>
<aspect>ef:typed</aspect>
</mandatory-aspects>
</type>
The problem is that when I press Download as Zip button for selected folder I get empty zip file. It comes from startNode method of ZipDownloadExporter.java:
@Override
public void startNode(NodeRef nodeRef)
{
this.currentName = (String)nodeService.getProperty(nodeRef, ContentModel.PROP_NAME);
path.push(new Pair<String, NodeRef>(currentName, nodeRef));
if (ContentModel.TYPE_FOLDER.equals(nodeService.getType(nodeRef)))
{
String path = getPath() + PATH_SEPARATOR;
ZipArchiveEntry archiveEntry = new ZipArchiveEntry(path);
try
{
zipStream.putArchiveEntry(archiveEntry);
zipStream.closeArchiveEntry();
}
catch (IOException e)
{
throw new ExporterException("Unexpected IOException adding folder entry", e);
}
}
}
Since custom folder has type ef:folder this check returns false:
if (ContentModel.TYPE_FOLDER.equals(nodeService.getType(nodeRef)))
and folder is not added to the zip.Is it a bug (maybe proper solution would be to check not only node's type but also parent type)? How it could be fixed without creating custom exporter for custom folder types?Due to project restriction type of folder couldn't be changed to cm:folder.
