What Operating System are you using (both controller, and any agents involved in the problem)?

Amazon Linux 2023 on controller and agents

Reproduction steps

Create a pipeline with a stage called 'Build' that in turn contains a parallel block containing a set of stages which each contain sequential stages, several of which are also named 'Build'. Conditionally skip any of the parallel stages (using when conditions).

The overall stage model of relevance looks essentially like this:

• 'Build' stage
  • parallel
    • 'A' stage, conditionally executed
      • 'Build' stage
      • 'Test' stage
    • 'B', conditionally executed
      • 'Build' stage
      • 'Test' stage

Expected Results

All stages render in appropriate fashion (e.g., gray circles, green checks, etc.); none are hidden.

Actual Results

None of the stages under the top-level 'Build' stage are rendered; it looks like this:

(The earlier and later stages can be ignored for the purposes of this bug; they're not relevant)

Anything else?

If the top-level 'Build' stage is renamed to something else (that is not duplicated with another stage name), everything renders as intended.

Are you interested in contributing a fix?

No response

Likely related to #358

Could you provide a sample pipeline that reproduces this please?

The stages don't need to do anything you could put a single echo step in them if you want..

[medianick]

Could you provide a sample pipeline that reproduces this please?

Yes -- here you go:

pipeline {
    agent none
    stages {
        stage('Build') {
            parallel {
                stage('A') {
                    when {
                        expression { false }
                    }
                    stages {
                        stage('Build') {
                            steps {
                                echo 'Build A'
                            }
                        }
                    }
                }
                stage('B') {
                    stages {
                        stage('Build') {
                            steps {
                                echo 'Build B'
                            }
                        }
                    }
                }
            }
        }
    }
}

This renders like this:

If I rename the inner 'Build' stages to 'Build A' and 'Build B', respectively, it renders correctly:
