      change the following expression

      m.setStatus( 1 + 2 * 3 + m.getStatus() );

      to

      m.setStatus( 1 + (2 * 3) + m.getStatus() );

      Show
      change the following expression m.setStatus( 1 + 2 * 3 + m.getStatus() ); to m.setStatus( 1 + (2 * 3) + m.getStatus() );

      Description

      When MVEL evaluates

      m.setStatus( 1 + 2 * 3 + m.getStatus() );

      the following exception happens.

      Exception executing consequence for rule "Hello World" in com.sample: [Error: no such method or function: m]
      		 
      [Near : {... m.setStatus( 1 + 2 * 3 + m.getStatus() ); ....}]

      If this is something like

      Exception executing consequence for rule "Hello World" in com.sample: [Error: no such method or function: m]

      m.setStatus( 1 + 2 + 3 + m.getStatus() ); <== Multiplication "*" is not used

      it works without above exception.
      This happens in both LHS and RHS with dialect "mvel"
