Hi!
I’m trying to create extension that get html array and do some operations with it.
Want to use core class
HtmlPackager
but when insert code inside my extension
@Override
protected void performExport(Map<DocumentReference, XWikiDocument> documents,
Map<String, Object> exportOptions,
XWikiContext xcontext) throws Exception
{
HtmlPackager packager = new HtmlPackager();
packager.setName("name");
packager.addPageReferences(documents.keySet());
packager.export(xcontext);
}
Get error
Failed to create attachment URL
class java.lang.NullPointerException: null
