Setting TreeGrid values causes to redraw SelectItem

[sibasish.palo]

Hi,

i am facing one issue where i am trying to load a tree on selection of a item on the click of a drop list item

below is the configuration in ui.xml file

<smt:UIHLayout ui:field="selectFolderLayout" height="20" width="100%" layoutHAlign="LEFT">

<smt:UILabel ui:field="selectFolderLabel" autoFit="true" wrap="false" contents="Select folder:"/>

<smt:UIDynamicForm ui:field="selectFolderForm" height="100%" width="100%" layoutHAlign="LEFT" >

<smt:UISelectItem showTitle="false" ui:field="folderViewMenu" showAllOptions="true" width="100%"/>

</smt:UIDynamicForm>

</smt:UIHLayout>

<smt:UIHLayout ui:field="folderListContainer" height="100%" >

<smt:UITreeGrid ui:field="folderpaneTreeGrid" canEdit="true" canCollapseGroup="true"/>

</smt:UIHLayout>

Here SelectItem will have some per-populated values to select (ex: folder1, folder2, folder3 ...), on select of an option it has to redraw the tree with new folder structure, below is the sample code

registerHandler(getView().getFolderViewMenu().addChangeHandler(new ChangeHandler() {

public void onChange(ChangeEvent event) {

String mode = event.getValue().toString();

if(mode != null){

getView().setTreeDataOnSelect(mode); //Mode will have the folder name which needs to be drawn on folderpaneTreeGrid

}

}

}));

public void setTreeDataOnSelect(String name){

ArrayList<FolderTreeData> folderTreeNodelist = new ArrayList<FolderTreeData>();
folderTreeNodelist = folderNodelist.get(name);//this is a map which will have all the folder structure with parent and child

createTree(); // problem code

FolderTreeNode[] nodeArray = new FolderTreeNode[folderTreeNodelist.size()];
FolderTreeNode node;
int count=0;

for(FolderTreeData data : folderTreeNodelist){
node = new FolderTreeNode(data.getFolderName(), data.getID(), data.getPath(), data.getParent());
nodeArray[count++] = node;
}

tree.setData(nodeArray);
folderpaneTreeGrid.setData(tree);
folderpaneTreeGrid.setShowHeader(false);
folderListContainer.add(folderpaneTreeGrid);
folderpaneTreeGrid.canEditCell();
folderpaneTreeGrid.setCanEdit(true);
folderpaneTreeGrid.setBorder("0px solid #999999;");
folderpaneTreeGrid.redraw();

}

public void createTree(){

tree = new Tree();
tree.setModelType(TreeModelType.PARENT);
tree.setNameProperty("Name");
tree.setIdField("ID");
tree.setParentIdField("Parent");

}


This is the code where i am setting the selectitem values

folderViewMenu.setValueMap(folderMap);
folderViewMenu.setDefaultToFirstOption(true);


when i change the value and select a folder name (ex: folder2) to draw into treegrid it redraws the tree structure with folder2 content but the selectitem defaults to first element which is folder1 always.

but if i comment out the createTree() method , selectitem displaying the selected values (which is folder2) but it doesn't draws the tree with folder2 content

can you please help on this


Thanks
