JTREE request edit mode for one node

hello,
my jtree is editable
tree.setEditable(true); // double click on a node and it goes in "edit mode"
I would like to set a specific node into "edit mode" (just like when you create a new folder in windows - new folder appears in edit mode - you just have to type the name of the folder)
//set the node selected
setSelectionPath(new TreePath(newfolder.getPath()));
// set the node in edit mode - does not exist ???
setEdit((new TreePath(newfolder.getPath())); ????
Second question:
how can I avoid a specific node from being editable ?
// set all the nodes editable !!
tree.setEditable(true);
thanks a lot !

Edit mode for a single section

Hi,
How can one enable edit mode for a single section in a UITableView with group sections.
Thanks.

Something like this should work for you:
@interface RootViewController : UITableViewController {
NSNumber *sectionToEdit;
@property (nonatomic, retain) NSNumber *sectionToEdit;
- (IBAction)doEdit:(id)sender; // test bed only
@end
@implementation RootViewController
@synthesize sectionToEdit;
- (void)dealloc {
[sectionToEdit release];
[super dealloc];
- (void)editSection:(BOOL)editing section:(int)section animated:(BOOL)animated {
UITableView *tableView = self.tableView;
self.sectionToEdit = editing ? [NSNumber numberWithInt:section] : nil;
[tableView setEditing:editing animated:animated];
// test bed driver
- (IBAction)doEdit:(id)sender {
static BOOL editing = NO;
editing = !editing;
[self editSection:editing section:2 animated:YES];
#pragma mark Table view methods
- (BOOL)tableView:(UITableView *)tableView
canEditRowAtIndexPath:(NSIndexPath *)indexPath {
if (sectionToEdit == nil)
return YES;
else if ([sectionToEdit intValue] == indexPath.section)
return YES;
else
return NO;
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView
editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewCellEditingStyleInsert;
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 3;
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
return 3;
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier] autorelease];
cell.textLabel.text = [NSString stringWithFormat:@"Section %d - Row %d",
indexPath.section, indexPath.row];
return cell;
Note that once a section is selected for editing, the above locks out all the other sections until the edit of the selected section is finished. I assume this is what you'd want. However if you're also providing a standard editing button to put the entire table in editing mode, you might want to change the control structure a little. E.g. if the standard button remains enabled during a section edit session, its action should probably set SectionToEdit to nil before starting the animation.

Making short text field in Display mode for one particular Purchasing

Hi All,
This is regarding Making the Short text field in Display mode of PR for one Particular Purchasing.. i am giving you a bit elaborate...We are into E-Catalog Procurement.I will do the shopping from the Vendors external catalog and i will return back to SAP.
While doing so, i dont want the user to change the Short Text field. I want that field shud display the Description. When i tried with the Screen Layout settings, it is fully grayed out and i am not able to see the Description of the Material. Is there any other options to get this enabled?. Please advice me on this settings to be done. Thanks in Advance.
With Regards,
Saakithyan

Hi
Define a Field selection key (new not the one which is assigned to document type) which makes short text editable in screen layout config. and assign it to functional authorization value in t.code OMET. (it should be numeric). Then assign that functional authorization value in user master SU01 for users with parameter id EFB.
Then it will work

Can you create an album in Edit mode for Elements 8?

I use a netbook and my screen resolution is maximized at 1024 x 600. I found another post that stated the screen will be cut off if there was less than 1024x768.
When I create an album I am not able to click "Done" at the bottom of the panel. This doesn't happen in Edit mode, only Organizer
I'm new to the program. Is there a way around this?
Thanks

Perfect, thank you. It worked. When I r

Make Editable only for one cell

Hi,
Is it possible to make one cell editable in a non-editable column of a matrix?
I have made a column non-editable. Now, based on a CFL value (which is in another column) selected, i want to make that row's non-editable column as editable.
My code, which fails:
If objMatrix.Columns.Item("V_1").Cells.Item(pVal.Row).Specific.value = 0 Then
objMatrix.Columns.Item("V_0").Cells.Item(pVal.Row).Specific.Enabled = True
End If

If is column set to non editable, you cannot allow to user change the vaule in any cell. The only way is set the column as editable and catch the events as
If pVal.ItemUID = "matrix" And pVal.BeforeAction = True And pVal.EventType = SAPbouiCOM.BoEventTypes.et_VALIDATE (for cghanges, gotfocus for accesing) And pVal.ColUID = "col" And pVal.ItemChanged = True Then
which will catch the changes of cell and if the cell isnt enabled for changes, set bubleevent to true.

Changing shared variable reference modes for all nodes in application. Shortcut?

I have a large application which makes extensive use of both network-published and single-process shared variables. I want to change the reference mode of every such node in the application from absolute to target-relative. Is there any way to do this without having to open every subVI in the application and use the right-click menu on every node?
Sean

I don't know of any shortcut, but if you want to change the reference node of everything in the application you could probably script it. I was thinking something similar to what I have below where you traverse the BD of a specific VI for all SharedVariableNodes and change the relative mode to Target Relative.
Depending on how your project is organized you can add some additional functionality before the open VI reference to go through and open the reference of every VI in your project.

How to apply Bundle Patch in Rolling Mode for 2 Node RAC

Hi Guys,
I have a 2 node RAC environment (11.2.0.3) where each node has there own local Grid_home and RDBMS_home.
I am installing a Rolling Bundle Patch with OPatch in this environment. The installation document says that "The order of patching in RAC install is GRID_HOME, then RDBMS_HOME" so i did the following.
1. stopped all oracle related services on node1
2. set oracle_home=<Grid_home>
3. applied the opatch
4. opatch succeeded on node1 and it says "The node 'NODE2' will be patched next... Is the node ready for patching? y
Here i am bit confused.
1. Should i shutdown the oracle services in Node2 and continue to patch the Grid_home ? If yes then the DB will be completely down for user access. This defeats the purpose of rolling mode which says there is no downtime.
2. Should i patch the RDBMS_home on node1 , start all the oracle services on node1 , stop the oracle services on node2 and then resume the opatch on node1 which is waiting to patch the Grid_home on node2 ?
Please advice.
Thanks,
Ashok Kumar.G

Hi Sebastian,
14613223 patch install instruction did not mention about opatch -local option.
Here is what i followed and completed the installation successfully.
1. Shutdown all oracle services on node 1
2. applied opatch for grid home and then rdbms home using "opatch apply -local" on node1
3. Started all oracle services on node 1
4. Shutdown all oracle services on node 2
5. applied opatch for gridhome and then rdbms home using "opatch apply -local" on node 2
6. Started all oracle services on node 2
7. executed post installation steps on the DB (@catwinbundle.sql & @utlrp.sql )
Thanks,

Elimination of Edit Mode for Views

Hi all,
I have created a view with a condition which says Activity is not "Save Request" . This is from within studio.
When I deploy the process and see the workspace, I do see the condition being applied but I also see that the condition created from within studio appears as Editable inside the workspace for that view.
I want to not show this condition to the end-user but at the same time, want to apply such a condition.
How can I do this?
This is in OBPM 10GR3.

You have a property in the view called isHidden that I think is what you are looking for.

Hello everyone,
Do someone meet this issue ? Do you know if it has a link with customization of ppm or customization of ITSM ?
Many thanks in advance for your replies !

1. Select checkbox Time Recording and Travel Expenses via CATS for project type. Path: SPRO —> SAP Customizing Implementation Guide —> SAP Portfolio and Project Management —> Project Management —> Structure => Define Project Types
2. Run/schedule a synchronization with the report DPR_CATS_CPR_TRANSF (Transfer of CATS Itemizations to Project Management Application).
