Setting Visible False to Canvas

Hi,
In WHEN-NEW-ITEM-INSTANCE-TRIGGER i am writing a code and in a particular event another canvas gets opened.
How to i restrict in moving to the canvas
Is there any way out???
Regards
Saugata

Solved it.
the autolayout property of a canvas must be set to false while resizing it, so the datagrid and other constrained components do not resize and the animation gets really smooth.

Set visible=false in Label not removing its space in screen

Hi All,
I have three labels ony by one having width=100% for all.
For some reason, now I want to make 2nd label invisible in
the screen.
So I set visible="false" for the 2nd label. Now I cannot the
see the text displayed by the 2nd Label, but I can see the space
occupied by the Label.
I mean that, now i am getting the first label text, and have
blank row which has the text earlier, but not now and thrid row
with 3rd label text.
Also I checked that, if I set the height of the 2nd Label to
0 then also its not completely removing the 2nd row, only
possibility I found was completely comment the code for the 2nd
Label is the only way to hide the 2nd row :)
Any help would be appreciated.

Hi Sujit,
Thanks for giving an useful tip which is new to me. But still
I can see a little space between the first and 3rd label.
Now this little space comes from the default space between
the controls. After few trials I found that there is a property
called "verticalGap" for the containter which holds these 3 labels.
I set the value to 0(zero) for verticalGap. Now the issue resolved
Thanks for a useful post

Restoring af:selectBooleanCheckbox value after setting visible=true

Using JDev 11.1; I have a table that displays data from a model object, and one of the columns contains true/false values which we render in the table using an af:selectBooleanCheckbox. All works fine except that user is able to hide the table by expanding other components which sets visible=false on the bounding component for the table. If user elects to redisplay the table by reducing the other component zoom, then the table displays again but the selected check-marks/tags do not return.
Thought initially it might've been because the query was being reissued on the table, but not so. More about the selected attribute on the af:selectBooleanCheckbox, which I have set to the default (false). So the value property is set to the table collection attribute as required to interface with the model, but I need to know what to set the selected attribute to. I can see that when the table is redisplayed, this default value of false is being sent through to the model which is discarding the values I want to retain.
I've tried some EL in the selected property to set it to true/false based on what's in the table, but the problem with that is that it becomes essentially a read-only control. I need to find some way to disable the value assignment when making the table visible again. Any suggestions?
Thanks,

Andrefs,
In ADF BC, one way we deal with this is by adding a transient Boolean attribute to the View Object with getters (translate 0/1 to false/true) and setters (vice-versa). Then, we bind the UI to the transient attribute. It's been so long since I've done EJB's, but could you take a similar approach?

Forms - Can't set a required field to visible=false

Hi,
I want to set a required field to visible=false but OIM 9.1 gives an error saying it is not possible.
Has anyone overcome this issue?
Thanks in advance

I guess, it should work; instead of html:submit, try with button.

Set the visibility false on click PopUp

Hi,
I want to set the visibility false of my component on the click of popup
but the problem is when i generate the Pop Up on Page then it lost the control of all the child's on that Page and when i set the visibility false of component then it is not set
Please guide.
Thanks,

You could use PopupFetchListener - to set the visibility of the button to false.
Here, is a sample based on your use-case.

Class display objects visible=false

Hi there,
I have an app that displays XML as items. I am taking the createLayout() and trying to create a class that i can call from my custom component rather than having tons of code in the same file. The issue i am having is that when i call it, and run/debug, the display objects (text,links,date..) all have their visible property set to false. This happens even though I set the property to true in my code. Please help!

Where I instantiate the class. List collection is an XMLListCollection which contains XML data.
private var createLayout:CreateLayout;
createLayout = new CreateLayout(listCollection);

container is from the Vbox class so I don't see that here and there might be something in there that is causing some problem.
But I don't think that is the only problem. I think this seems like the same problem that you have going in your other post.
I don't see anyplace that you addChild your CreateLayout instance. container has been added to your CreateLayout instance, but where is the CreateLayout instance added to some other display list.
Also it looks like almost everything you add to canvas is set to be invisible. So without knowing what is in a Canvas instance it is hard to know what would show up anyways.

Jabber 9.2 and StartCallWithVideo set to false not taking

The StartCallWithVideo option doesn't seem to working in Jabber 9.2 (tried 9.2.0 and 9.2.2). Tried false and FALSE for value.
The jabber-config file downloads fine and has all the settings below on PC and the DockedWindow is not visible so the settings are working, but the calls start with video still and on the Jabber GUI under call section the start calls with video is selected.
When I make call to someone else it starts with video unless I manually set to not start calls with video.
Not finding any bugs on this.
Anyone seen this before or know how to get it working if it isn't a bug?

Anyone have fix to this issue with IM&P 9.1.1, I have UC Service profile setup right and the setting set to false and my client is getting current XML file but still starts calls with video. I've tried both upper case and lower case for the false value. Other settings from my jabber-config file are working just fine.
FALSE
I've been thru the links above and documentation again but not seeing a option anywhere on CUCM UC profile pages or IM&P to disable this.

Maybe Flex SDK bug: Setting visible of DataGrid item renderers

Hi all, I'm still a noob at flex but this looks a bit strange to me.
I've been trying to hide a button renderer in a DataGrid but it just wouldn't hide. I've been setting visible inside the mxml and also in the the class that extends buttonbut it just wouldn't hide. I then overloaded the visible property set/get and traced what was setting the property to true and found that inside DataGridBase.as the function setupColumnItemRenderer always sets visible of the renderes to true.
DataGridBase.as
protected function setupColumnItemRenderer(c:DataGridColumn, contentHolder:ListBaseContentHolder,
                    rowNum:int, colNum:int, data:Object, uid:String):IListItemRenderer
        var listItems:Array = contentHolder.listItems;
        var item:IListItemRenderer;
        var rowData:DataGridListData;
        item = listItems[rowNum][colNum];
        if (!item || itemToUID(item.data) != uid
            || columnMap[item.name] != c)
            item = createColumnItemRenderer(c, false, data);
            if (item == null)
                return null;
            if (item.parent != contentHolder)
                contentHolder.addChild(DisplayObject(item));
            // a space is used if no data so text widgets get some default size
            columnMap[item.name] = c;
            if (listItems[rowNum][colNum])
                addToFreeItemRenderers(listItems[rowNum][colNum]);
            listItems[rowNum][colNum] = item;
        //[Matt] moved from inside the block above to outside because
        //the item definitely exists at this point, and always needs
        //its data refreshed
        rowData = DataGridListData(makeListData(data, uid, rowNum, c.colNum, c));
        rowMap[item.name] = rowData;
        if (item is IDropInListItemRenderer)
            IDropInListItemRenderer(item).listData = data ? rowData : null;
        item.data = data;
        item.visible = true;
        if (uid && colNum == 0)
            contentHolder.visibleData[uid] = item;
        return item;
Why does it do this? Shouldn't it respect the visible property already set for the renderer in mxml and not force it to true on init?

Renderers use the visible property for recycling. Invisible renderers are not supported. The hit detection logic would find it the cell it belongs to even if it was invisible. You can set alpha=0, but it won't stop the hit detection logic.
Why are you trying to hide a renderer?

Issue with af:tree's visible=false on IE

Hello,
I have an ADF page containing two af:tree components. For both rendered is set to true and visibility is set to false. For both the trees height has been set to 500px. Based on selection criteria either of the two trees has to be made visible. No issues on Firefox. However on IE, both the trees are occupying space even though visibility is set to false. When I try to show the second tree, it shows up down below after 500px of white space. So, even though first tree is not displayed, it still occupies the space. Please let me know the solution.
Thanks,
Lalitha.

Hi,
sounds like a bug to me. You can try an af:switcher component, though it only shows one tree at a time then

$ie.visible = $false

I use the following to assign text and search ok if set $ie.visible = $true. But the text cannot be assigned if set $ie.visible = $false. The text box is still empty after run $ie.Document.getElementById('TextBox_ID') = 'This is'.
Is there a way to fix it? Thank
$ie = New-Object -COM "InternetExplorer.Application"
$ie.visible = $true
$ie.Navigate('http://searchtext.com')
While ($ie.busy) { Start-Sleep -Seconds 1 }
$ie.Document.getElementById('TextBox_ID') = 'This is'
$ie.Document.getElementById('Search_ID').click()

What is this line supposed to do" "ie.Document.getElementById('TextBox_ID') = 'This is'"
An ID cannot have a space in it.
You cannot directly assign a value in that way. You need to assign the value member.
A web page that I not vivible can very easily not behave as expected. It all depends on the design of the web page.
if($tb=$ie.Document.getElementById('TextBox_ID')){
    $tb.Value='This is the new value'
}else{
    # textbox not found
¯\_(ツ)_/¯

What are the side effects of setting "_object_statistics=false"?

Hi,
On a 10.2.0.3.0, due to frequent ORA-04031 errors, we have been recommended to set objectstatistics=false in init.ora and bounce the database.
Metalink Bug ID: 3519807
Going through the available documentation on net, I found that this parameter would have same effect as setting STATISTICS_LEVEL=BASIC or even worse.
Documentation (for statistics_level) says following options are affected.
* Automatic Workload Repository (AWR) Snapshots
* Automatic Database Diagnostic Monitor (ADDM)
* All server-generated alerts
* Automatic SGA Memory Management
* Automatic optimizer statistics collection
* Object level statistics
* End to End Application Tracing (V$CLIENT_STATS)
* Database time distribution statistics (V$SESS_TIME_MODEL and V$SYS_TIME_MODEL)
* Service level statistics
* Buffer cache advisory
* MTTR advisory
* Shared pool sizing advisory
* Segment level statistics
* PGA Target advisory
* Timed statistics
* Monitoring of statistics
We have daily schema statistics gathering schedule in place so I feel query performance should not be affected (of course, this is my assumption).
I just wanted to know what else would be affected due to this.
Thanks in advance.
Regards,

Please let me know your ideas/inputs.

Thanks for looking at this post. We have resolved the issue for ourselves by working with our DBAs to narrow down where the problem actually started. We found that the particular SQL we were looking at was not the issue. In a chart on a subsequent page (via a click through), we were actually running into where apex was starting to consuming memory but we were catching it later.
What we found was that when we had a chart query that was SQL containing a pipeline function, the memory usage went up. And within 10 minutes, the server would crawl to a halt. To release the memory, the DBAs would have to bounce the Apex instance. When I changed the query to be a function returning SQL, the problem stopped. I don't know what the correlation was between SQL and moving to a PL/SQL function returning SQL.
I am not even 100% positive of the pipeline function being the cause. I only know that this started happening about the same time as when I implemented the pipeline function. I understand you are leery of a one-second function/query running up that kind of utilization. No one here believed me either (including me really). We figured it HAD to be a coincidence. But once I changed the query from SQL to a function returning PL/SQL, our problem went away.
Thanks to all who looked at and thought about this.

To set Visibility for KM Documents

Hi
I uploaded some documents in knowledge Management. Now i want to set visibility for those documents, country wise. That country name is not in the list. How can i add the particular country?
Thanks,
Kusuma

Hi,
When you create repository to upload documents in knowledge management administration there are certain features are displayed which you can define for your repositories. So, please check there if country option is available. I would prefer to create different repositories for different country as administration will becomes eaiser.
Thanks
