Tree grid - Have all records from root to leaf

[jose.hello]

Hello,

With treegrid widget we can have the selected record or the selected path wich is a string.

How can I have all records from root node to selected leaf node (SelectionType.Single) ?

[jose.hello]

I found the solution :

ArrayList<ListGridRecord> listrec = new ArrayList<ListGridRecord>() ;

ListGridRecord lgrec = getAvailableModule().getSelectedRecord();
listrec.add(lgrec);
String end = lgrec.getAttribute("CATEGORY_ID");
while (!lgrec.getAttribute("PARENT_ID").equals(end)){
	for (ListGridRecord rec : getAvailableModule().getRecords()){
							
	     if (rec.getAttribute("ID").equals(lgrec.getAttribute("PARENT_ID"))){
								listrec.add(rec);
								lgrec = rec;
	     }
	}
}

getAvailableModule() Is my treeGrid

But is no method to do that automatically ? For performance
