Issue getting table cell renderer component from JTable

Greetings,

 

I wrote some js to retrieve the rendered value from a cell in my application's JTable, but TestComplete keeps locking up when calling the method: getTableCellRendererComponent()

 

Here is my code:

/*
* Returns the displayed value in the specified JTable cell
* 
* Parameters:
* table - a JTable object
* row - integer index of the row
* column - integer index of the column
*/
function getRenderedValue(table, row, column) {
  let value = null;
  let columnModel = null;
  let columnObj = null;
  let renderer = null;
  let component = null;

  if (0 > row) {
    Log.Error(`Row index must be greater than or equal to 0: ${row}`);
    return null;
  } /* if: the provided row index is less than 0 */

  Log.Message(`Getting rendered value found from cell: (row=${row}, column=${column})`);

  value     = table.getValueAt(row, column);

  columnModel = table.getColumnModel();

  Log.Message(`Getting column object by column index: ${column}`);
  columnObj = columnModel.getColumn(column);

  Log.Message(`Getting renderer for column: ${columnObj}`);
  renderer  = columnObj.getCellRenderer();

  Log.Message(`Get component for renderer: ${renderer}`);

  component  = renderer.getTableCellRendererComponent(table, value, false, false, row, column);

  Log.Message(`Get text for component: ${component}`);

  if (aqObject.IsSupported(component, "getText")) {
    value = component.getText();
  }

  return value;
} /* end function: getRenderedValue(table, row, column) */

The table I am providing to this function is a simple JTable, but it does use a custom TableModel and a custom TableColumnModel. All of the renderers within this table are custom as well. I have tried calling this function for the first cell and row in table which is essentially just a String value and it still fails.

 

I would appreciate anyone's insight as to why the test - and java application - lock up.

 

I eventually have to kill the process for my application in order to have testcomplete finally release its hold on the application.

 

I've attached the logged messages for executuion:

Hi @BTscott,

Hmmm, I have never seen this error posted to the Community. Could you please refer this question to the Support Team? They will need to reproduce it in their test lab.
