getNodeInfo is called for every item, irrespective of which level it is in.
Below code is what i am doing in getNodeInfo.
based on TreeItemType, i make a new nodeinfo. i know nothing about which
level etc. it is in, only the type of the item.
In your case u will have 2 ifs one for FOlder and one for File. For File,
there will be "static" data provider. isLeaf will return true for File.
In case of Folder u will most probably make a AsyncDataProvider and
onSuccess call updateRows(....).
This folder-dataprovider will retrieve Folders and Files and again call
getNodeInfo on each.
I really dont see the issue with different object types at the same level.
If u want a working example, i can help you build one. Hope i understood
your issue correctly.
NavTreeItem nti=(NavTreeItem)value;//this is the value passed to
getNodeInfo.
if(nti.getType()==TreeItemType.RECORD_SET){//get the type of
item.
.....//build the data provider,cell, keyprovidr,
valueupdater.
........
return new DefaultNodeInfo<NavTreeItem>(recSetDataProvider,
recSetCell,multiSelectModel,null);
}else if(nti.getType()==TreeItemType.CHILD_ITEM1){
....//build a different dataprovider, a different cell, etc.
....
NodeInfo<NavTreeItem>childItem1NodeInfo= new
DefaultNodeInfo<NavTreeItem>(conceptDataProvider,
conceptCell,multiSelectModel,null);
return childItem1NodeInfo;
}else if(nti.getType()==TreeItemType.CHILD_ITEM_WITH_BAR){
....//build the 3rd type of data.
.....
return new DefaultNodeInfo<NavTreeItem>(conceptDataProvider,
cc,multiSelectModel,null);
}
