Frun1na opened a new issue, #4664: URL: https://github.com/apache/rocketmq-dashboard/issues/4664
### Before Creating the Bug Report - [x] I found a bug, not just asking a question. ### Apache RocketMQ Dashboard version master (web/src/utils/messagePayloadPreview.ts) ### Which part of the dashboard is this about? Message sending — property payload preview ### Bug description When the same property key appears twice in the send-message form, the payload preview reports an error whose message says the duplicate "will overwrite the earlier values" (重复属性会覆盖前面的值). That is not what happens: `buildMessagePropertiesFromRows` skips later duplicates and keeps the first value, and the pasted `key=value` text parser (`parseMessageProperties`) also never overwrites an existing key. Both input modes are first-value-wins, so the warning describes the opposite of the actual behavior and can mislead users into expecting the last value to win. ### Steps to reproduce 1. Open the message sending page and choose the form mode for properties. 2. Add two rows with the same key, e.g. `traceId=first` and `traceId=second`. 3. The preview reports "重复属性会覆盖前面的值：traceId", but the normalized properties keep `traceId=first`. ### Expected behavior The warning should state that only the first value is kept, matching the actual behavior, e.g. "重复属性仅保留第一个值：traceId". ### Additional context I have opened PR #4663 that corrects the message and adds a test assertion so the copy cannot drift from the behavior again. -- This is an automated message from the Apache Git Service.
