i just use the DSL editor on my eclipse to create an DSL file. each time i add an DSL condition and save it in my DSL file.once It is done i close that file and open again where the editor is not showing the updateed DSL file.Hence i got the Parser errors on my DSLR file.But i open and see that DSL file in TextEditor which is showing the updated file.I can see some errors on my eclipse Log. Please find the below erroe log. could any one can help to resolve this issue .
