IntelliJ 12 complains "cannot resolve symbol" with Groovy Markup Builder

In my project I'm using groovy markup builder to create html content. for exampe

        builder.table {
            tr {

              td("Data1")

              td("Data2")

            }

       }

IntelliJ inspector now complains that he cannot resolve the symbols table, tr and td. This wasn't a big issue until using the new

darcula theme. Now all those unresolved symbols are marked red in the text and even worse they clutters the problems bar at

the right side of the editor window.

Does anyone know how to tell the inspector to ignore that unroesolved symbols?

Thanks a lot
