What steps will reproduce the problem? add this test to BasicFilterTest: public void testLiNoUl01() { assertEquals("\n" + "<ul><li>test1</li>\n<li>test2</li></ul>", wikiModel.render("<li>test1\n<li>test2", false)); } (maybe add newlines after/before <ul>/</ul> depending on the implementation)

What is the expected output? What do you see instead? MediaWiki surrounds all <li> elements with an implicit <ul>

Commited r7519 Please check if this is ok for you.

yes, thank you (I also ported it to 3.1 in r7583)
