I installed the eclipse web page editor from the help->updates->Ganymede Update Side-> Web and Java EE Development. - version 2.1.0
Whenever I try to open an html page though, I get the error:
java.lang.NoSuchMethodError
An error has occurred. See error log for more details. org.eclipse.wst.sse.ui.StructuredTextEditor.isBlockSelectionModeEnabled()Z
Any ideas on how to resolve this?
