[antlr-interest] <AST>:0:0: expecting IDENT, found '<ASTNULL>'

[Muhammad Masoom Alam]

Dear all

during tree evaluation , we often this exception/error

<AST>:0:0: expecting IDENT, found '<ASTNULL>'
or

<AST>: expecting IDENT, found '<empty tree>'

is there is any specific reason for these errors ,
becaz program is running as well, and if tree
evaluation grammar is correct , why these errors are
comming and how we can avoid them or stop them.

i means some specfic soltuion ??

with Best Regards
Muhammad.
