Well, you are right for the 2). But i want to keep in the list grid only records that pass where clause for example booleanFoo = true (in the database). And if the user uncheck booleanFoo for 3 records and pres update their booleanFoo is updated in the database and they are removed from the list grid why should i force new fetch if i know what i updated and what i should remove from the listgrid. The application is admin iterface that will not be used from 2 or more user simultaneously, so making new fetch is unneeded.

Any response on this one?

This I do receive data from RPC service, but i have callback that says how to transform the data coming from the rpc in json. I the assets select item that is not part from the dynamic form, but serves as a filter for the grid everything works, the assets are loaded as key/value. May be the problem is in the data presentation( json?)
The addeditDialog is just a window that displays the form.
Do you need the RPC implementations?
Regards.

KeyValueJsonAsyncCallback just transforms json key:value to Record
My AssetJsonDataSource is tested and working with SelectItems.

I would need to see all your code to understand what you're doing...

It looks like you're using JSON and client side only I'm using RPC and Objects (server side only).

Your declarations are a lot different from what I have so I would have to see it all.

Reparenting a node in a tree grid using GWT-RPC datasource doesn't work

Hello everyone,

I am using a GWT-RPC datasource with a tree grid. The problem I have is that reparenting a node doesn't actually move the node to its new location in the tree. It does work when the node is dragged and dropped, though.

Here are the details.

To reparent the node, I assign the primary key field (ID) of the new parent to the node being moved's foreign key field (PARENT_ID), which, in a tree, points to the parent:

[CODE]
// New parent
ListGridRecord newParent = treeGrid.getSelectedRecord();

// Set the record's PARENT_ID attribute equal to the parent ID
record.setAttribute(PARENT_ID, newParent.getAttribute(ID));

// Update the record
treeGrid.updateData(record);
[\CODE]

This results in a call to my datasource's executeUpdate method, where I call my server-side service and call response.setData, and processResponse with the response:

	protected void executeUpdate(final String requestId, final DSRequest request, final DSResponse response) {

		// Retrieve record to be updated.
		final ListGridRecord record = new ListGridRecord(request.getData());
		final GroupDto group = new GroupDto();
		copyValues(record, group);

		// Ask the server to update the group's properties corresponding to the specified module record.
		adminService.updateGroupProperties(group, new AsyncCallback<GroupDto>() {

			public void onFailure(Throwable caught) {
				// The server returned an error status; inform the module.
				response.setStatus(RPCResponse.STATUS_FAILURE);
				processResponse(requestId, response);
			}

			public void onSuccess(GroupDto updatedNode) {
				// The group's properties were successfully updated on the server so finish updating the record.
				copyValues(updatedNode, record);
				ListGridRecord[] responseData = new ListGridRecord[1];
				responseData[0] = record;
				response.setData(responseData);
				processResponse(requestId, response);
			}

		});
	}

I can see that the server comes back with the updated record, which has the ID of the new parent. I can also see that the record in the tree is updated and, likewise, has the ID of the parent, however, it stays in its original location, not under the new parent.

I verified that executeUpdate(...) is called with the same parameters (i.e., operationType = UPDATE and updated record) when the user drags and drops the node, but, in that case, the node *does* move to its new location under the new parent.

Using the Developer Console I found that dragging and dropping passes two extra request parameters to the update operation versus invoking updateData explicitly, namely '_parent_isc_ResultTree_4: Obj{ID:305746317786}' and '_selection_2: false':

10:19:37.232:INFO:ResultTree:isc_ResultTree_4 (created by: isc_OID_1):Updating cache: operationType 'update', 1 rows update data:
[
{__ref: com.smartgwt.client.widgets.tree.TreeNode@10a250a,
id: "305829641916",
title: "Brasing Meats",
parentId: "305833462635",
_parent_isc_ResultTree_4: Obj{ID:305746317786},
isFolder: undef,
_selection_2: false}
]

My question is, how should I call treeGrid.updateData(...) to have the node move to its new location, as when dragging and dropping?

Thanks so much for your insights.

In this example the Datasource is used in a ListGrid.

Primary Datasource Code:

public class MemberListGridDS extends GWTRPCDataSource<MemberRecord> {

	public MemberListGridDS() {
		//Replace with actual RPC Service
		super(SGWTMemberService.Impl.getInstance());

		DataSourceIntegerField intField = new DataSourceIntegerField("mbrid");
		intField.setPrimaryKey(true);
		intField.setCanEdit(false);
		addField(intField);
		
		intField = new DataSourceIntegerField("websid");
		intField.setCanEdit(true);
		intField.setEditorType(new WebSelectItem());
		intField.setForeignKey("weblgds.websid");
		addField(intField);

SelectItem Code (This uses another Datasource):

public class WebSelectItem extends SelectItem {

	public WebSelectItem() {
		WebListGridDS ds = new WebListGridDS();
		ds.setID("weblgds");
		setValueField("websid");
		setDisplayField("dsc");
		setEmptyPickListMessage("No data in table");
		setPickListWidth(450);
		
		ListGridField websidField = new ListGridField("websid");
		ListGridField dscField = new ListGridField("dsc");
		setPickListFields(websidField, dscField);
		
		setOptionDataSource(ds);
		setAutoFetchData(true);
	}
}

SmartGWT 2.0 updates?

Hi all,

I see Sanjiv tagged netname's 303 issue for v2.0, excellent (Thanks for raising this netname, btw).

Which brings the question, when is 2.0 expected ;)

Thanks if you know the answer,
Justin

Will 2.0 support GWT 2.0 or is it a bug fix and feature release only?

Thank you,
