I just want to confirm this bug and add a patch. This bug is related to two lines in class HtmlTreeRenderer.
BTW i took one day to get the tomahawk-sources compiled in my eclipse-ide and finally managed it by removing this single class from the tomahawk-binary and putting the HtmlTreeRenderer.java-sources to my workspace.
i checked out the 'current'-folder (http://svn.apache.org/repos/asf/myfaces/current/)
1) no way to compile tomahawk with maven: maven2 produced constantly build errors (only at the tomahawk-package, myfaces-core went fine)
2) tried to compile only sources from package "org.apache.myfaces.custom.tree2" - there are some sources missing: (HtmlTree.java, TreeTag.java) last seen in version 1.1.6 !? (/myfaces/tomahawk/tags/1_1_6/core/src/main/java/org/apache/myfaces/custom/tree2), searched the whole myfaces-repo - but nothing (automatically generated ?)
i personally think open source is a great idea and i want to support those projects whenever its possible to me. but in this case it was extremly complicated.
