Data Binding Issue in WebTable Template Objects

Type             : Bug
Priority         : Medium
Gambas version   : Master
Product          : Web components


Description
-----------

Summary
Incorrect data retrieval using Last.Text when using design-time template objects with grouped events in WebTable.Data.
Description
I have implemented data loading within the Data event of two WebTables using different approaches:
    • WebTable1: Uses design-time template objects with events grouped via the Group property.
    • WebTable2: Uses runtime objects created dynamically with grouped events (e.g., Dim ObjetoX AS WebButton(WebContainerX) AS "EventX").
Issue Details
In WebTable1, when Click or Activate events are triggered, attempting to retrieve loaded data via Last.Text yields incorrect results:
    1. Click Event: Always returns data from the last record loaded into Data.Control.
    2. Activate Event: Returns the default text from the original template WebTextBox instead of the specific row data.
Observations
This issue does not occur in WebTable2. Since those objects are instantiated at runtime within the Data event, they maintain a correct direct reference to the Data.Control context.
