**Description:** I am facing a visual refresh issue in the labeling interface. My project involves pre-annotated tasks where each bounding box (`rectanglelabels`) contains unique metadata in the `meta` field (specifically a `label` and a `hierarchyId`).

**The Goal:** I want the interface to dynamically display the specific metadata of the **currently selected** bounding box in a Sidebar/Header. When an annotator clicks on Box A, they should see “Label A”; when they click on Box B, the text should update to “Label B”.

**The Problem:** Even though the JSON correctly contains different values for each region, the UI does not refresh the displayed text when switching between regions. It seems to “stick” to the metadata of the first region detected in the task and never re-renders the Header/Text value upon new region selection.

**Example of my JSON structure:**  
{  
“id”: 1,  
“result”: [  
{  
“id”: “box\_1”,  
“type”: “rectanglelabels”,  
“meta”: { “label”: “Search Button”, “hierarchyId”: “ID\_001” },  
“value”: { “x”: 10, “y”: 10, “width”: 20, “height”: 10, “rectanglelabels”: [“button”] }  
},  
{  
“id”: “box\_2”,  
“type”: “rectanglelabels”,  
“meta”: { “label”: “Login Button”, “hierarchyId”: “ID\_002” },  
“value”: { “x”: 50, “y”: 50, “width”: 20, “height”: 10, “rectanglelabels”: [“button”] }  
}  
]  
}

\*\*My Interface XML (simplified): \*\*

Question:\*\* Is there a specific tag or a way to force the UI to re-bind the `$meta` variables when a new region is selected? I’ve tried using `perRegion="true"` in various tags, but it doesn’t seem to apply to `Header` or `Text` elements for display purposes.
