Error description

• In RTS or Decision Center, when editing the definition of a
  decision table condition column or a decision tree condition
  node, surrounding the whole condition with parentheses, using
  the "(..." and "...)" items of the popup menu, leads to a page
  with the following stack trace:

  The exception is raised when the popup menu item is clicked or
  selected. It will occur whether the opening or closing
  parenthesis is selected first.
  This behavior does not occur in Rule Studio / Rule Designer, nor
  does it occur when editing an action rule in RTS with the guided
  editor.
  

Local fix

• no workaround
  

Problem summary

• The rule parser for the token model does not support the
  opening parenthesis if this is the only parenthesis in the
  expression.
  

Problem conclusion

Temporary fix

• Do not enclose expression in parenthesis
