Read up on the Reflection API, java.lang.reflect
this has excellent methods by which you can inspect the internals of a class file or an object.

Add component in task list

Hello All,
I have an issue with adding component in task list (for example task list number EIMN-68) via transaction IA05.
When I try to add component to operation, I get the message *
Standard BOM PAEIMN-68 4 already exists
Message no. 29771
Diagnosis
You want to create a standard BOM for standard object PAEIMN-68 with usage .
A BOM already exists for this standard object and usage. You cannot extend a standard a standard BOM.
Procedure
Check whether the standard BOM is suitable for standard object PAEIMN-68 and usage . If it is not, you need to create the BOM for another standard object.
Is there any special way to create material master for such components.Whats the solution.
Please help
Cheers
Sunny

Hi Pithan, how are you..
I want to add components.
Just now I was able to add components. I explain how:
When i added component number in operation, and press enter, system gave me the error that standard bom already exist. In the same screen I changed the BOM usage to 3 as universal usage. After this usage only, system allowed me to add components. No other bom usage allowed me to do so.
Also, why system took me to BOM screen if I just want to add components.
I wait for your reply.
thanks and regards
Sunny

Facing problem to add component in a panel dynamically

I face serious problem to add component dynamically on a jpanel. can any one help me?
I have one panel inside a frame. And I have another 3 or 4 panel. dynamically i want to change the panel inside the frame with the other panel.
can anybody help me with source code?
Your earliest response is highly appreciated.

remove is reflected immediately without calling
validate() but it does not work for adding. please
give me some code.Post a small demo code that is generally compilable, runnable and could reproduce your problem. See: http://homepage1.nifty.com/algafield/sscce.html and http://www.yoda.arachsys.com/java/newsgroups.html

Dynamic add component to panel, it does't work

I want to add a label in a panel when you click button.
I used revalidate() and revalidate() method, but it didn't appear in panel.
HELP ME?? WHAT'S WRONG!
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jPanel1.add(new JLabel("Hello"));
jPanel1.revalidate();
jPanel1.repaint();
}

i add Layout manager to panel. It works. Thanks,
So tricky things for dynamic adding component:
1, setup layout manager to container (such as panel),
2, add component to container
3, call revalidate() method to relayout these components in container
You can't miss any one of those.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
jPanel1.setLayout(new FlowLayout());
jPanel1.add(new JButton("Hello"));
jPanel1.revalidate();
}

Cannot add component with id '_id0' and path

Hello together!
Thanks for your help so far you really helped me a lot.
Now most of the time my application is working fine, but I get sometimes the error:
javax.servlet.ServletException: cannot add component with id '_id0' and path : {Component-Path : [Class: javax.faces.component.html.HtmlOutputText,Id: _id0]} to its parent component. This might be a problem due to duplicate ids.
     javax.faces.webapp.FacesServlet.service(FacesServlet.java:121)
     org.apache.myfaces.component.html.util.ExtensionsFilter.doFilter(ExtensionsFilter.java:122)
What can I do to prevent that?
Thanks a lot.

I don't know if the html could would help, but I post it anyways as I am really going crazy:

I receive "Database access denied" when trying to add component 4543BD

I receive "Database access denied" when trying to add component 4543BD to my schematic. This component was added from a previous version. I'm using Multisim version 12.0.0 Student edition.
Solved!
Go to Solution.

Hi Diarra,
I checked my database and the 4543 is not in the Student Edition. If you opened a schematic that was created in a higher version such as the Educaiton Edition and copied the part to your database, when you place this part you will get the access denied message.
Attached is a schematic with the part, you can open it and build you circuit around it.

Runtime add component inconsistency

Hi All,
When I add component (hyperlink) at run time on integrated server I see different dialog than when I do it on stand alone WLS. On WLS I have no short desk and show component has no option to enter expression but just check box which is critical. Does anybody know what update should be done to add the capability to WLS that I can enjoy on integrated server (Documentation, links)?
JDeveloper 11.1.1.5.0, WLS 10.3.5
Thanks,
SNikiforov

ALWAYS execute the following if you add or remove components from an already visible container:
container.revalidate();
container.repaint();

Example for add(component,object)

Hi,
I have a program and am trying to understand that. it is constructing a jpanel. I need to know what this means.
panel.add(panelA,"4,4,4,10");
what is 4,4,4,10
could any one give me a small example of how to use add(component,objet)
Appreciate all your help
Thanks

Not sure what that is about. Its not normal syntax.
Read the Swing tutorial on [url http://java.sun.com/docs/books/tutorial/uiswing/layout/visual.html]How to Use Layout Managers for better examples and explanations of adding Components to Containers.

Illegal component position when add JLabel to JtextPane

Hi all,
I want to add a JLabel to a JTextPane, the label shoud be put in the lines of text just like the normal text. I have some questions:
1. How can I put the label in the position we want, when I use the method add(label, textPane.getStyledDocument().getLength()), it generates exception :"illegal component position"
2. How can I set the width and the height of the label so that user cannot know that I used the label. I mean the text on label and the normal text on JTextPane must look the same. Of course I know the length of the caption of the label
Thank you very much

How can I put the label in the position we want, I'm not sure you can add a component using that method. I think there is an insertComponent(...) method to use. Also you may need to make the text pane uneditable first if I remember correctly. Something like:
textPane.setEditable(false);
textPane.insertComponent(...);
textPane.setEditable(true);
How can I put the label in the position we want, label.setFont(textPane.getFont());

Add text after a component in JTextPane

Hi all,
I insert a JLabel to JTextPane, after that I want to insert a string by the method Jtextpane.getStyledDocument().insertString(pos,string,attrSet). However, I dont know how to decide pos parameter. I tried to add the position where I put JLabel with the length of the text in JLabel but I got BadLocationException. The problem will be solved if I know how to decide the length of the label according to the length of the text on it. Pls help me with this. In that case, how can I set the height of the Label so that the text in label look the same as the normal text in JTextPane
Pls help me
Thank you very much

how can I set the height of the Label so that the text in label look the same as the normal text in JTextPaneWeren't you given an answer to this question in one of your earlier postings?

ComponentView does not redraw component in JTextPane Cell Rend

We have created a JTable implementation that uses JTextPanes as cell renderers/editors so that text styles and the like are available. We want insert a component, such as a JButton, into the JTextPane. However, the component is only visible when the cell is in an editable state. In the renderer, the ComponentView looks like it has set aside the space where the component is to be, but the component is not visible.
I have looked at this problem for several days now, and have only determined that this seems to be occuring at a low level. What I have found is that the ButtonUI's update method is not called when the document is in the cell renderer, while it seems called continuously in the cell editor (on each caret blink).
Does anybody have any insight as to the problem? I have submitted this as a bug to Sun but wanted to find out if anybody else has come across anything similar to this.
Thank for any help.

Here is sample code to reproduce the problem:
// Main Class
* Main frame for the testing of the component not painting. This simplifies
* an issue we have come across when trying to set up using a JTextPane as a
* renderer/editor as the cells in a table.
* Under these conditions we have found that a component inserted into the JTextPanes document
* only appears in the editing state of the cell, whereas the rendering state leaves
* the spacing for the component but does not make it visible.
* Note that creating a JTextPane with the one of these documents will show the component,
* even when not editing.

Hi, I came across the forum and found your problem is very similar to what I am having now. Your post has been a year old, I just wonder if you come up anything productive to what you had? Could you let us know what you (or Sun) find out if you do have one? Thanks.

Add component to cluster

Hi,
I have a cluster X of 6 controls (different types). I have an other one (Y) of 7 indicators. The first 6 of them correspond to the ones of X, and I need to put a numeric constant in the seventh. I did not find any other way than unbundle X, rebundle all its components with a seventh input and wire it to my output cluster Y. Can I jump the unbundle of X step by just adding a component, as, for example, when we build an array with to inputs: 2D array and single column. We don't have to separate each column of the 2D array before adding the other one... Thanks.
Phil

AFAIK, clusters are static structures, but you have other possibilities, e.g.:
* Add the seventh item also to cluster X, but hide it in the display there (right-click..advanced..hide control) or slip it under the border.
* Make the cluster Y as a cluster of [cluster X + indicator #7], this way you don't need to unbundle X.
