How to get all children of root components
Jdev 11.1.1.7.0
I have a requirement where I need to disable all the entry / editable user interface components in the page at the click of a button.
I intend to make in the bean by getting the liaison of the outermost component layout and then using the method getChildren() for this UIComponent.
So for all the components of the user interface in the list, I'll put the disabled true property.
However, I am facing a challenge here. My page got several components of layout in it.
GetChildren() method would not search recursively for all user interface components (including inside other components of layout as panelgrouplayout).
Is there a way I can achieve this?
You can write a method that runs along the element tree by calling itself recursively as
// reset all the child uicomponentsprivate void resetValueInputItems(AdfFacesContext adfFacesContext, UIComponent component){ Listitems = component.getChildren(); for ( UIComponent item : items ) { resetValueInputItems(adfFacesContext,item); if ( item instanceof RichInputText ) { RichInputText input = (RichInputText)item; if ( !input.isDisabled() ) { input.resetValue() ; adfFacesContext.addPartialTarget(input); }; } else if ( item instanceof RichInputDate ) { RichInputDate input = (RichInputDate)item; if ( !input.isDisabled() ) { input.resetValue() ; adfFacesContext.addPartialTarget(input); }; } }}

How to get all the fonts in the paragraph?
Hi all
Especially in Indesign Javascript list how to get all the fonts section (without a loop in each character). For example, I used "Minion Pro" to the first character and all other characters are "Zapf Dingbats" fonts. I use code below to get the paragraph font. But it shows only first typeface. If multiple fonts are used for including the paragraph then I need all the list fonts or result "undefined".
var myPara = app.selection [0] .paragraphs [0];
Alert (myPara.appliedFont.FontFamily);
Thank you and best regards,
Robert S

BlackBerry Smartphones home screen: how to get all emails to a folder?
I must be looking too hard for what should be a simple answer, there are currently 3 icons on the homescreen different email, one for each email address I have. (this does not include my sms & icons FB msg) How can I get all the emails to go to a single rather than a separate icon for each folder?
Thank you
Dave in State of WA
Hi and welcome to the Forums!
If your device OS has the possibility, you can dictate what shows in Messages:
- Home screen > Messages > > Options > (main Message list settings) (settings of the Inbox) or > check / uncheck what you want to see the/remove messages
You will always have the secondary icons, but you can hide them and manage simply all email through the main Messages app.
Good luck!

How to get all parents of tree node to select
I have a tree, and when the user clicks on an item in the tree, I want to get all the parents of the selectedItem node.
So, if I have this XML:
< Products >
< item >
< code > 1001 < / sku >
< value = "100" / >
< / point >
< item >
< code > 2001 < / sku >
< value = "250" / >
< / point >
< item >
< code > 3001 < / sku >
< value = "300" / >
< / point >
< / product >If the user clicks on the sku 1001, I want to get something like this:
< Products > < point > < sku >
Also, if I have a custom component, possibly based on the tree or maybe not, and if this custom component shows the XML real and used can click XML elements or attributes XML, how to use the selected item to get the parent nodes, so if they click the value = "100", I get this:
< Products > < point > < sku > < quantity >
I need this because I have a set of fields, and users will drag their attributes or elements of XML node in my fields to define a mapping between the XML and my fields.
The selectedItem is just a snippet of XML code cut off from its source XMLListCollection and I might be able to search the XMLListCollection, but that if there were say < code > items to more than one level in the XML? I'm guessing that a search may return several hits for a selected item, when I want the real parent to the actual selected node nodes.
Thank you very much!
[path of the var: Array =]
var parent: XML = xxxx.selectedItem.parent)
{while (parent)}
Path.push (parent. LocalName())
parent = parent.parent)
}
Or, I don't have your question and xxxx.selectedItem is 'detached' extract XML code?

How to get all the SMS messages?
Hi all
I want to get all the SMS messages in my application, but I can only find the API to get the mails.
I have search the Forum and know the method of listening to SMS messages, but not to get all SMS messages in the Inbox.
Can someone help me? Thank you.
I'm afraid you cannot access the SMS Inbox and not either, you can manipulate the messages as soon as they reach the Inbox.
However, as you already mentioned, you can listen to them on their way to the Inbox. -
How to get * all * Contacts
I have a very useful sample application called "address book", which uses the ContactService API to enter contacts and their details, and display them in a list. The problem is, showing contacts that there is only a small fraction of all my contacts. It seems that everyone on Facebook, for example, more appear in this list.
Is there a way to really get all the contacts, equivalent to the list in the application Contacts BB10?
The current answer is no, see Paul's response in this thread...

In bulk API - how to get all contacts that when, in a specific campaign
Hello
I am trying to retrieve all contacts only when a specific campaign ID.
I looked in most activities of the api and it seems that I can not filter the results according to the type of activity: entry campaign.
Basically what I tried and succeeded is to get all the contacts that are in a specific activity as "EmailOpen" type and a specific campaignid.
but I need to extract the results of entry of campaign activity.
is there a way to do this using the API as a whole?
If this isn't the case, I can do it using a different api? or by creating a segment / list based on the entrance to the campaign activity?
10 x,
Eliram
In bulk API will give you feature dataset and data activity (ver 2). Entry into a campaign is not an activity that the contact is made, but it is rather something that you do everything for them - so therefore, that is not a valid activity to expect from the bulk API.
This information is available through REST:
It is used in the operational report "Entry campaign report" under the active campaign options menu. Like all OTHER calls, number of max is 1000. That would be 1 call of the API by campaign, by 1000 responses. Slots are at the time Unix.
