Unary minus preceeding negative value causes calculated item to become not supported

    Details

      Description

      Create two calculated items. The first one will have expression like:

      -1
      

      and the second one will reference the first item like:

      -last(host:key1)
      

      Type of information: Numeric (float) for both of them.

      The second item becomes unsupported with the following error:

      Cannot evaluate expression: expected numeric token at "-1".
      

      In the process of expression evaluation server simply substitutes trigger functions with their value without putting them in parentheses, which can sometimes produce invalid expressions (like "--1" in our example) for further evaluation stages.
