Hi all,
I have a problem about vertical alignment of custom components (shown in a blue frame) in a treeGrid. You can see it on attached picture.
I create components using next code :

@Override
		protected Canvas createRecordComponent(final ListGridRecord record, Integer colNum) {
...

this a code for initializing treeGrid:

   treeGrid.setDataSource(propertiesDS);
   treeGrid.setShowRecordComponents(true);
   treeGrid.setShowRecordComponentsByCell(true);
   treeGrid.setLoadDataOnDemand(false);
   treeGrid.setCanEdit(false);
   treeGrid.setAutoFetchData(true);
   treeGrid.setAlternateRecordStyles(true);
  		//treeGrid.setRecordComponentPosition(EmbeddedPosition.WITHIN);
		 
   treeGrid.setRecordComponentPoolingMode(RecordComponentPoolingMode.DATA);

   treeGrid.setWidth100();
   treeGrid.setHeight100();
   
   TreeGridField nameField = new TreeGridField("name", "NAME", 200);
   TreeGridField valueField = new TreeGridField("value1","VALUE", 260);
   TreeGridField descriptionField = new TreeGridField("description", "DESCRIPTION");
   treeGrid.setFields(nameField, valueField, descriptionField);

This is an error code:
WARN:DynamicForm:isc_DynamicForm_10:ignoring bad or negative top: NaN [enable ‘sizing’ log for stack trace]

Please help, is it a bug or?

Setting component position to WITHIN and calling setSnapTo(“T”); should cause the component to show up at the top of the cells.

This area has had some work recently - if the above doesn’t work, can you try with the latest nightly build.
If you continue to see the bug let us know. We’ll basically need to see a standalone test case so we can run it on our end, reproduce the problem and determine whether its a bug / how to resolve it.
