Hi I don't think use underscore could be a good choice, because for generated ids, the prefix is j_id, so methods like UIComponent.findComponent will not work correctly.
I have checked it and it is a bug. It should use UINamingContainer.getSeparatorChar(FacesContext) instead a constant. Please file an issue on myfaces issue tracker here: https://issues.apache.org/jira/browse/MYFACES so it can be fixed regards, Leonardo Uribe 2011/6/15 Christoph Dietze <[email protected]>: > Hello, > > we changed the default SEPARATOR_CHAR from colon to underscore.
