Load, unload some component from some container

I want to make something like this.....
So when I click one of the tree component ( the leaf ) or maybe other action, in component ( right of the tree, maybe jpanel ), the gui loads jtextarea, but when I click other component of the tree ( other leaf ), the gui unloads the jtextarea, and loads jlabel.
How do I achieve that? The first thing comes to my mind is using card layout..... But this is my gui main area. I don't feel comfortable using card layout for gui main area.
Thanks.

container.remove(oldComponent);
container.add(newComponent);
container.revalidate()
container.repaint()

How can I load up some pdfFiles from adobe Reader on my iPad into my Adobe Creative Cloud?

How can I load up some pdfFiles from adobe Reader on my iPad into my Adobe Creative Cloud?

There is no app for uploading files from an iPad to the Adobe Creative Cloud, and the iPad security model does not allow for upload of files from the browser. The Adobe Touch Apps do provide syncing up to the Creative Cloud but none of them are really designed for working with pdf files.
You can connect your iPad and move the files to your computer. From your computer you can upload the files via a web browser.

Load/Unload Component from Main Application

I want to load in my main application 2 components. At this moment I load them with this:
<components:loadProject id="loadPrj" visible="false" click="loadPrj_clickHandler(event)" verticalCenter="7" horizontalCenter="0"/>
and I only set visible to true. Inside this component there is a canvas.
But, is there any other way to do this using an AS class file? I would like to load/unload it on click, not only set true/false to visible.

For dynamic creation and destruction of objects, you want to use ActionScript.
So in your main app file, you might have a button that triggers a click handler that does this:
private function myClickHandler()void {
 var b1:CustomComponent = new CustomComponent();
 var b2:CustomComponent = new CustomComponent();
 /// Be sure to add them to the display list if they are visual components
 myPanel.addElement(b1);
 myPanel.addElement(b1);

Applet not loading in some environments

Hi,
We have an applet that works for 99% of our users but for one user the applet does not start. Are there any specific proxy / browser settings that could prevent the applet from loading properly? Outputs from the java console for the working users show the following lines:
basic: Applet loaded.
basic: Applet resized and added to parent container
basic: PERF: AppletExecutionRunnable - applet.init() BEGIN ; jvmLaunch dt 116394 us, pluginInit dt 399250 us, TotalTime: 515644 us
basic: Applet initialized
basic: Removed progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@1abab88
basic: Applet made visible
basic: Starting applet
basic: completed perf rollup
Start Method
basic: Applet started
basic: Told clients applet is started
In the example where we have an issue we only see the following lines:
basic: Loading applet ...
basic: Initializing applet ...
basic: Starting applet ...
basic: completed perf rollup
basic: Stopping applet ...
basic: Removed progress listener: sun.plugin.util.GrayBoxPainter$GrayBoxProgressListener@b51404
basic: Destroying applet ...
basic: Disposing applet ...
basic: Joining applet thread ...
basic: Joined applet thread ...
basic: Finding information ...
basic: Releasing classloader: sun.plugin.ClassLoaderInfo@a89ce3, refcount=0
basic: Caching classloader: sun.plugin.ClassLoaderInfo@a89ce3
basic: Current classloader cache size: 1
basic: Done ...
basic: Quiting applet ...
It seems like for some reason its attempting to start but then instantatly stops .... we don't see any exceptions in console.
Relatively new to applets so any advice would be appreciated

"can't load because some files are already in use" - Adobe reader! How do i close whatever i can't find that they say is in use!?

Can anyone help me get Adobe reader 11 installed??? The error message when I'm practically done says the file can't be loaded because some files are already in use - and it refers to Adobe reader! What do I do to get past this??? Help! I need to install adobe!
I had been having a problem after I tried to do an adobe update, so i deleted and tried to reinstall the program and it won't let me ! Any suggestions???

Hi Jody414,
Use the Acrobat Cleaner tool ( Download Adobe Reader and Acrobat Cleaner Tool - Adobe Labs ) to remove Reader completely from the machine.
Download Reader 11 from: Adobe - Adobe Reader Distribution and install and check.

Site does not load after some minutes of creation or after restart the server

Hello,
I have been asked to create a test enviroment identical to the production enviroment. So, what I did was:
Backed up the production web application's content database: Prod_WSS_ContentDB
Created new test servers (domain controller, sql server and sharepoint 2013 server) in a new, completely isolated, network environment, without any connection with the production environment (specifically Azure)
Created a new web application in test environment with a new content database.
Dismounted the new content database with powershell: Dismount-spcontentdatabase Test_WSS_Content
Copy the Prod_WSS_ContentDB database to the test sql server and restored it with Management Studio.
Mount the Prod_WSS_ContentDB databe to the web application with powershell:
Mount-spcontentdatabse Prod_WSS_ContentDB -WebApplication http://testsp/
Then, when I type http://testsp in the browser it redirects me to http://testsp/SitePages/Home.aspx
and the site loads exactly as the production environment.
But, after some minutes, or if I restart the Sharepoint Server, when I navigate to
http://sitesp I am redirected to http://testsp/SitePages/Home.aspx
as expected, but the site does not load, the browser just show a complety blank page.
The Central Administration site loads normally.
Trying to fix it I found that if I dismount the content database Prod_WSS_ContentDB, then mount the test database Test_WSS_Content,
then navigate to the site, dismount Test_WSS_Content and finally mount again Prod_WSS_ContentDB, the site loads normally, no blank page, but after some minutes or if I restart the same happens again.
For the error event I receice in event viewer it seems that the problem is related to database. I have not found a solution for this error... How can I solve this?

Hi,
According to your post, my understanding is that Site does not load after some minutes of creation or after restart the server.
Please make sure you create a test environment for existing production site correctly.

Calling a method in the Custom ADF component from JSF page

HI.
I have created some custom compoents by extending the core ADF Components. Like i have a ComboBoxDefault component with it's ComboBoxDefaultTag.java and Controls.tld file.
Now my requirement is i want to bind my label to this component from the JSF page. like
<fwcontrols:label binding="#{listComponents.comboBoxDefaultLabel}" id="label1"/>
<fwcontrols:comboBoxDefault binding="#{listComponents.cmbLocales}"
value="en_GB" id="comboBoxDefault" autoSubmit="true" label="label1">
<f:selectItems value="#{listComponents.locales}"/>
</fwcontrols:comboBoxDefault>
In my JSF page the label will have an id, and that id will be specified in the label tag of the component.
In Tag.java file i have overrided the setProperty(FacesBean facesBean). In this method i have bind all my properties. In core JSF the setProperty method is provided with the UIComponent parameter, so i can call my method in component also. Which is not in case of ADF Faces.
My main point is how i can call my method setLabel() which is in ComboBoxDefault.java so that i can set the label.
Thanks in Advance.

Thanks for all your replies. I want this kind of a functionality because Im trying to invove a DC (Child DC) from a Parent DC such that the Child DC's view is displayed onto the view container of the Parent DC. I have embedded using 'interface view of a component instance' in the Parent Window and am able to create the component and set usage though the onPlugDefault of the Child View.
But I observe that when i make a call from the parent, the flow is like this:
1. The wdDoInit of the Child Component Controller gets triggered first.
2. Then the wdDoInit of the Child's VIEW gets triggered
3. and THEN the onPlugDefault of the Child Component Interface View
What I had actually wanted was to Fire onPlugDefault where Im calling a method LoadData(), after which the Child DC's view must be triggered so it can display the fetched data.
What is actually happening is the view gets displayed, but no data is displayed in the view.
Right now I have just given a work around where Im triggering LoadData() of the COmponent COntroller from the wdDoInit of the VIEW.
Is there a better way to do this? I find it strange that I have to load the Data from the view.
Thanks
Jack

How can I call a public function in one component from another component?

I have two components: Form and Confirmation. Form is a Canvas and Confirmation is a TitleWindow.
Form contains several controls and a submit button. Confirmation contains an OK button. When the user clicks the submit button, the Confirmation appears over the Form (Form is blurred). When the user clicks the OK button on the Confirmation, I want to run a function on Form to set some default values in the controls.
How can I address the function in the Form component from the Confirmation component so I can fire the function?
Thanks!

Loading Chart of Accounts from SAP into Account dim in BPC automatically

Hi,
for my client I would like to take a predefined flat file from SAP containing chart of account details (account id, description and parent) and load and process them automatically using dtsx packages in BPC 7.0 MS.
Also, I want the package to able to be able to change details when it finds an already existing account id (e.g. if the description changes) and only for the properties contained in the flat file (i.e. keep the property values the same in BPC for those properties which are not in the extract for existing account records), or to add new accounts for those that don't exist. I don't want the existing dimension completely replaced, as the SAP file won't contain info for fields like ACCTYPE, or TYPEELIM for example.
I find the help in Data Manager extremely confusing and am not sure which bits are current or have been superceeded.
I am an application consultant with limited knowledge of DTS/ SSIS and I wonder if someone can give me a step by step detail of what I must do to achieve this. I am sure that many people would like to do something similar.
regards
Scott.

Here is what you need to do in the SSIS package.
1. You need to create exactly same structure as MBRAccount Table. Let's say tmpMBRAccount
2. Export Account data from SAP as FlatFile
3. You need a Script to fill in ACCTYPE or other properties that doesn't exist in SAP but mandatory for BPC account dimension. This script will change exported Flatfile.
4. Import step3 flatfile into tmpMBRAccount table.
    Some users import data into MBRtable directly but it is not good because if error happens,
    there is no way to roll back until restore table from backup database.
    If users use temporary table as we do, Admin task will backup and roll back if error happens.
5. Run Admintask and point tmpMBRAccount table as source table.
6. You need another script to update Excel member sheet from updated mbr table.
    If you don't have this script, data member will be inconsistent between excel member sheet and MBR table.
Some customer add more steps to validate members or error handling.
If you are not an expert of SSIS, I think you need a technical consultant for doing this.
There are an example package in BPC sample package folder but it is very basic one.
Thank you.

Loading an xml file from an xml file

I'm trying to load an xml file from an xml file, but I'm
having problems. My first xml file is really simple - it only
contains one attribute with the name of another xml file in it
(eventually I will have multiple xml files in here and run a loop
on them...this is why I want to load an xml file from an xml file).
Currently, with the code below, I can get the main xml file
to load ("main.xml"), but I cannot get the secondary xml files to
load FROM the main.xml.
I want to then take childNode values from the secondary xml
file and use them within my .swf in text boxes and whatnot.
Any guidance? I think I'm going wrong on the line where I'm
saying "i.newxml.load(i.attributes.location);"
- How can I get this to work?

johnypeter:
I tried changing the code inside the loop to use just
"newxml" instead of "i.newxml", and I declared with "var newxml =
new XML();" - was this what you were thinking?
kglad:
The reason I tried to use the loadXML() function in the loop
was so that for each node in my "main.xml" it would load the new
xml file listed - this is a no-no? Do you have any ideas as to what
I could do?
For the for-loop, what should I change in it? I'm not great
with loops so I tried to modify some code from another loop I found
in another forum thread - not the right way to do it here?
Also, what should I trace? The value of the _root.address, or
i.attributes.location? I have created dynamic text boxes on my
stage to see if the correct value from the xml file loads (ie. the
name of the xml file within the xml file) and it does, but now I
don't know how to put that information into ANOTHER loadXML()
function and get the node information from it - does that make
sense???
Below are the examples of the xml files I am using. In the
first one, main.xml, I will have a list of multiple xml files, each
with the same nodes and elements as in the details.xml file
(different values, of course).
This is just to give you an example of what I'm trying to
accomplish - pulling ALL the addresses and phone numbers from
multiple xml files. I cannot manually collect this information, as
it is dynamic, and will be updated in each individual details.xml.
I was hoping to collect the information by simply adding to and
updating ONE xml file - main.xml.
Do you think this can be done? Am I going about it the wrong
way? I'm quite limited in AS knowledge, which is why I'm piecing
together code from other posts!

Set location of component in a container

I'm looking for a way to exactly specify the location for a component in a container.
For example let's say i have some JPanel and i want to add a JButton to it at coordinates x=100, y=50.
Is this even possible?
All the lay out managers seem to prevent this because they auto-arrange the components in the container.

You can try to use something like this:
import java.awt.Container;
import java.awt.Insets;
import java.awt.Dimension;
import javax.swing.JButton;
import javax.swing.JFrame;
public class AbsoluteLayoutDemo {
    public static void addComponentsToPane(Container pane) {
        pane.setLayout(null);
        JButton b1 = new JButton("one");
        JButton b2 = new JButton("two");
        JButton b3 = new JButton("three");
        pane.add(b1);
        pane.add(b2);
        pane.add(b3);
        Insets insets = pane.getInsets();
        Dimension size = b1.getPreferredSize();
        b1.setBounds(25 + insets.left, 5 + insets.top,
                     size.width, size.height);
        size = b2.getPreferredSize();
        b2.setBounds(55 + insets.left, 40 + insets.top,
                     size.width, size.height);
        size = b3.getPreferredSize();
        b3.setBounds(150 + insets.left, 15 + insets.top,
                     size.width + 50, size.height + 20);
     * Create the GUI and show it. For thread safety,
     * this method should be invoked from the
     * event-dispatching thread.
    private static void createAndShowGUI() {
        //Create and set up the window.
        JFrame frame = new JFrame("AbsoluteLayoutDemo");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        //Set up the content pane.
        addComponentsToPane(frame.getContentPane());
        //Size and display the window.
        Insets insets = frame.getInsets();
        frame.setSize(300 + insets.left + insets.right,
                      125 + insets.top + insets.bottom);
        frame.setVisible(true);
    public static void main(String[] args) {
        //Schedule a job for the event-dispatching thread:
        //creating and showing this application's GUI.
        javax.swing.SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
}pane.setLayout(null) will give you what you want.

LOAD UNIT OF COMPONENT IS VERY LARGE (GENERATION LIMIT)

We are experiencing this meesage when compiling an ABAP WEB DYNPRO Application: "LOAD UNIT OF COMPONENT IS VERY LARGE (GENERATION LIMIT)"
When Checking the Generation Limits In the Context menu, I have determined our size of Generated Load in bytes is to big.
The documentation of recommendations is to restructure the program. I am not clear what this means and how this would reduce the Generation Load in bytes. Any ideas would be appreciated.

> How should we reorganize the application and at the same time ensure smooth and user-friendly handling?
We only want to use one Explorer window.
Using multiple components doesn't mean that the user will notice any difference. Component usages can be embedded within one another. Using the ALV for instance is a perfect example of a component usage.
>- Even the SAP reference application "LORD_MAINTAIN_COMP" (37 views) is way too big, according to the recommendation. Is there a better example from SAP?
I wouldn't consider LORD_MAINTAIN_COMP a reference applicatoin. It was one of the veryfirst WDA's shipped by SAP before we learned some of these lessons ourselves. Have a look at the guidelines for Floorplan Manager if you are on 7.01. The FPM provides a very good (and well used by SAP) framework for building large scale WDA applications.
>- How could a complex transaction be built and at the same time stay in the green limit area (< 500k
As described the usage of multiple components avoids the generation limit and is recommended for large scale applications.
>- What at all is the problem in loading 2 Megabytes of data into memory? Could you please describe the technical background in more detail?
It has nothing to do with 2Mb into memory. It has to do with the generation load size in the VM for the generated class that represents your WDA Component. The ABAP compiler and VM have limits (like all VMs and compilers) on total load size and the maximum size for operations and leaps. Generated code can be extremely verbose. Under normal conditions, these load limits are almost never reached in human created classes.
In 7.02 we backported the 7.20 ABAP complier - which in additon tpbe rewritten to support multipass compelation, also increases some of the load limits. However the general recommandation about componentization still stands. Componentization of you WDA application improves maintainabilityand reusability over time. My personal rule is that if you are getting between 10-12 views in your Component, it is time to think about breaking out into multiple components.
>- Is there a maximum load size, which would lead to an error (reject of generation)?
Yes there is. However the workbench throws warnings well in advance. At some point it won't even let you add more views to a component. However if you continue to add content to the existing views, you can reach a point where generation fails.
