BUG: CC007 incorrectly errors on valid comparisons

[MonochromeChameleon]

#403 introduced checking for Condition statement, but incorrectly flags comparisons between two flow variables as invalid. In the PR description it says:

Unknown or invalid operands. Eg fault.name = null is fine, fault.name = invalid_client is invalid. (The RHS should be quoted)

but if invalid_client were a flow variable, this comparison would be valid.

@MonochromeChameleon - I dont think you have a flow variable on both sides of the operation. In your case invalid_client must be a string for the condition to work

[MonochromeChameleon]

@ssvaidyanathan that's just the example from the error comment, but in the more general case, you should definitely be able to compare two flow variables, e.g.

<Step>
    <Name>rf-invalid-format</Name>
    <Condition>detected_format != required_format</Condition>
</Step>

I'm having a similar issue, same code error but when I use multiline conditions or the "not" operator.

Ex:

<Condition>
    proxy.pathsuffix MatchesPath "example" and 
    request.verb = "GET"
</Condition>

and

<Condition>not(proxy.pathsuffix MatchesPath "example")</Condition>

@MonochromeChameleon - Apigee as a product doesnt support comparing two flow variables from what I understand.

[ssvaidyanathan]

@matnsc - I have submitted a PR to allow not.. For now you can use ! instead of not. The multi line condition should be available in 2.46.3. Can you please try and let us know. Its part of #402

@ssvaidyanathan APIGEE does support using two flow variables, In my case I check org and env names

I expect org and env names in resource URI, and then use flow variables organization.name and environment.name against the extracted values form resource URI but due to this it's failing

@Polaratom - Can you share an example of what you mean please?

I have run some tests and found these results for what Apigee accepts on the right-hand-side of operators:

| operator              | RHS                 |
| --------------------- | ------------------- |
| Equals                | literal or variable |
| GreaterThanOrEquals   | literal or variable |
| GreaterThan           | literal or variable |
| LesserThanOrEquals    | literal or variable |
| LesserThan            | literal or variable |
| StartsWith            | literal or variable |
| NotEquals             | literal or variable |
| EqualsCaseInsensitive | literal only        |
| JavaRegex             | literal only        |
| MatchesPath           | literal only        |
| Matches               | literal only        |

I did test the lastest PR (#416) in some of our proxies that use multiline, not (and other named operators) and double equals which previously failed CC007 tests, now it's working as expected.

Latest version (2.46.3):

PR #416:

[DinoChiesa]

Excellent, thank you for the confirmation.
@MonochromeChameleon - Can we close this one out now?

[ssvaidyanathan]

Please test using this version and let us know if you find any issues.
