Tools: signature String method() - Not found couse exists.

After checkout jsf-pages marks methods as "missing".
i.e.: <h:commandButton action="#

" value="Einloggen" />
told me that "Method must have signature "String method()" but has signature "String method()""

Ever i pres Ctrl+LmB to enexus, editor jumps to implementation "public String einloggen()".

-> So this error-message is wrong.

Is critical why i cant build projects contains errors.
