Hi,
I'm trying to find a tool which will let me debug apps that are largely written in JavaScript but use FABridge to control my Flex Application. Ideally something that will allow debugging of both sides of the app at the same time, or as part of the same process. Any suggestions most welcome.

The reason I am using a column to ascertain visibility of the check box is due to using a vo to populate the header renderer and I need to make a comparison between the grid renderer current item and it corresponding column header vo.

Renderers on the recycle list get visible=false and set back to true when used again. If you completely hide a renderer, I'm not sure what would happen. Other than that, I would find a way to introspect the renderers and see if they did compute visible correctly for their data. It seems odd that your lookup of data.val is based on a column.

The responsibility lies now with the method below for showing or hiding the check box: override protected function commitProperties():void { super.commitProperties(); var row:int = listData.rowIndex+1; visible = false; for( var i:int = 0; i < data.ff.length; i++ ) { if( data.val[listData.columnIndex-1] != undefined && data.val[listData.columnIndex-1].option[i] == row ) { visible = true; } } if (owner is ListBase) selected = ListBase(owner).isItemSelected(data); } And dammit if its still doing exactly the same as before?!?

Essentially I have a DataGrid with a custom itemRenderer displaying CheckBoxes. Within the renderer I am running a comparison on a value within the renderers data i.e. data.my_val and the current grid row and column values. Depending on whether the data value equals a specific row I show or hide the check box. I achieve this by running the comparison logic with the overridden updateDisplayList method below which works fine until scrolled. override protected function updateDisplayList( unscaledWidth:Number, unscaledHeight:Number ):void { super.updateDisplayList( unscaledWidth, unscaledHeight ); var row:int = listData.rowIndex+1; for( var! i:int = 0; i < data.ff.length; i++ ) { if( data.val[listData.columnIndex-1] != undefined && data.val[listData.columnIndex-1].option[i] == row ) { btn.visible = true; } } } The issue is on scroll all of the check boxes are displayed/hidden incorrectly and the whole grid messes right up! Any ideas pls would be appreciated. Si
