Description:
Similar issue was reported and fixed in DROOLS-2854, there is another pattern which does not work.
When MVEL evaluates
m.setStatus( 1 + 2 * 3 + 4 * m.getStatus() );
the following exception happens.
{noformat}
Exception executing consequence for rule "Hello World" in com.sample: [Error: no such method or function: m]
[Near : {... m.setStatus( 1 + 2 * 3 + 4 * m.getStatus() ); ....}]
{noformat}

[JBoss JIRA] (DROOLS-3477) MVEL: expression (1 + 2 * 3 + 4 * $v ) causes "no such method or function " for bind variable
by Hiroko Miura (Jira)
Hiroko Miura created DROOLS-3477:
------------------------------------
Summary: MVEL: expression (1 + 2 * 3 + 4 * $v ) causes "no such method or function " for bind variable
Key: DROOLS-3477
URL: https://issues.jboss.org/browse/DROOLS-3477
Project: Drools
Issue Type: Bug
Components: core engine
Affects Versions: 7.9.0.Final
Environment: MVEL2 2.4.0 Final
Reporter: Hiroko Miura
Assignee: Mario Fusco
When MVEL evaluates
m.setStatus( 1 + 2 * 3 + m.getStatus() );
the following exception happens.
{noformat}
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() ); ....}]
{noformat}
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"
