Combo box in jsp : implemented by struts tiles

Hi,
I have few problems with JSP...
we have devided the body part in the tiles into two parts
initially..................
body1: jsp with combo box
body2: a blank jsp
if the user selects an option from the combo box..in onchange function ..iam getting the value of the selected option..and iam doing form.action="action selected by user" ... so that it will go the struts-config then inturn will call the action then by forwarding success..will go to the struts-config file again ..then by have name="seccess".. it will call path="somedefinition"....this definition is defined in the tiles-definition file...
where again...extending some standard definition by overriding ..
body1:jsp with combo box
body2:jsp related to the selected option..in the combo box
second time.. in body1: again we r calling original jsp na..it will show default select only na??

It's not nice to highjack someone elses thread. I posted a reply http://forum.java.sun.com/thread.jsp?forum=45&thread=552915 (though I shouldn't have, shoulda done it here). if you have questions post them to this thread instead. Leave the other one to the OP's question.

Combo Box in JSP

Hi,
I am a student and working on a class project. In my application at some point, I need to provide a combo box where user can select multiple values and those values should automatically be printed in a text area provided below the combo box. Is this possible?

The Only Way By which U can achieve this is by a scripting languages like javascript,vbscript......
Nvr By JSP(Is nothing but a servlet under execution @ background of webserver) as it is meant for Server Side Programming Surely not for Client Side Dynamic Action.
Make use of <select> with multiple property set to true....
and then.... append selected values in the second textbox.
You may go throgh the code given below
c whether that can help u out.....
CLIENT.JSP
=========
<%@ page language="JAVA">
<html>
<head>
<script>
function change(){
var x=document.getElementById("mySelect")
document.getElementById("result").value = ""
for(var i=0;i < x.length;i++){
if(x.options.selected == true)
document.getElementById("result").value = document.getElementById("result").value + " "+x.options[i].value
</script>
</head>
<body>
<select id="mySelect" size="4" multiple onchange="change()">
<option value='Apple'>Apple</option>
<option value='Pear'>Pear</option>
<option value='Banana'>Banana</option>
<option value='Orange'>Orange</option>
</select>
<input type='text' value='' size='10' name='result' id="result">

Problem in Combo Box Values

Hi Members,
I have an combo box in a user designed screen. I have to list the sales order number for an chosen customer in the combo box.
My problem is that all the values are not listing for that customer.
Sample coding is as follows:
strSQL = "select DocNum from ORDR where CardCode='" & objform.Items.Item("4").Specific.String & "'"
        objRS.DoQuery(strSQL)
        While Not objRS.EoF
            objCombobox.ValidValues.Add(objRS.Fields.Item("DocNum").Value, objRS.Fields.Item("DocNum").Value)
            objRS.MoveNext()
        End While
Please kindly help me in this regard.
Thanks,
Venkatesh.R

Hi Venkatesh,
Please insert a breakpoint in this line
objRS.DoQuery(strSQL)
Then code the value of the strSQL variable and execute it on the SQL Server Management Studio. I'm guessing it returns no records, so there will be no values in the ComboBox.

Vítor Vieira

Problem with combo boxes and the reset button in certain situations

Hi Everyone,
i have a problem to make the reset-button function properly in an what-if analysis dashboard.
The dashboard uses two combo boxes that are not visible at the same time. In my application the second combo box only appears when a dedicated menu (label based menu button) has been activated.
So i have combo box 1 when menu A is active an dand combo box 2 when menu 2 is active.
After starting the dashboard initial values are fine. If you then directly change to menu 2 (seeing combo box 2 with
the correct default value) and press the reset button, the dashboard returns to the initial view, showing
the menu 1 with the correct default value. If you now switch back to menu 2, you will see, that the combo box 2
is empty (i.e. nothing selected).
I also tracked the destination cells for the combo box value results as well as the source cells for the "selected item" and the
destination cells for the "Insert Selected Item". All this values seem to be correct. Therefore i assume that
this is an issue of event handling. Maybe the combo box 2 does not refresh its selected value because it is already
invisible when the values are restored.
This case can easily be simulated by placing two combo boxes and a push button (that changes the visibility of
the combo boxes) and the reset button on the canvas.
Maybe someone can help. I am able to provide a test xlf, if neccessary.
Thanks,
Oliver
P.S. I am using Xcelsius SP4 (Version 5.4.0.0)

Hello Debjit_Singha_86,
thank you for your support. At the moment i have the following setting:
label based menu
- General: Insertion Type "value" from a list of ID's for the menu-items to a dedicated cell (current menu ID, say tab1!$A$1)
- Behavior: Selected item (position) fixted to item 1
hidden combo box
- General: Insertion Type "position" to a dedicated cell with the current choice (say tab1!$B$1)
- Behavior: Selected item (position) to the same cell (tab1!$B$1)
Can you give me a hint on how to connect the two components according to your solution, so that the label based menu sets the default for the hidden combox box only in case, that the reset button is pressed?
Thanks,
Oliver

Problem w/"combo boxes" cause the user to double click for the dropdown menu, but not for everyone.

I have created a form with Adobe Acrobad Pro 9.
There are a few "drop-down" boxes for people to choose options from. I created them with the "Combo box" option. They work perfectly fine on my laptop (Lenovo T500 windows 7, with all updates up to date.) I sent the file to another exact same computer and that's when the problem came up. When you click on the drop-down, the list will quickly appear and then disappear. Then if you click it again it will stay open so you can choose your option. However this only happens on "some" computers but not everyone's. I emailed the exact same form out to other people in my office and they do not have any problems with the form. There is no need to double click the drop down, it will just open up properly for them.
Has anyone come across this? And if so, is there maybe a setting on these specific laptops that is preventing the "combo box" to not work properly? I need to use this specific laptop as a "Kiosk" like a "check out" station for users to fill out the form to check out equipment. I will be running in Reader so people can not make changes to the form. (both the Acrobat Pro 9 version and the (most up to date) Reader version of the PDF form does the same "double-click" problem) I need a date drop down and an equipment type drop down.
Any suggestions would be greatly appreciated !
Thanks !

I've got this kind of problem with a form of mine (designed with LCD) :
- combo boxes with font-color changing event handlers on :enter
- on Acrobat 9 Pro : no problem
- on Reader 8.3 :
- first click seems to execute the event handler but stops the combo's opening
- second click does open the combo
Do you have event handlers on combo:enter ?
Could the difference between comps where it works and comps where it doesn't be Acrobat's version ?

Problem with Combo Box in a Dialog Box

I have a dialog box that includes a combo box.
For some reason the combo box shows up under the first text box. In other words, the combo box is not separate from the first field. It has the following:
ComboBox with Sequence showing, then Enter Identifyer
Textbox URL
Textbox Enter Resource 1
Textbox Enter Resource 2
Textbox Enter Resource 3
Textbox Enter Resource 4
Textbox Enter Resource 5
It's putting the combo box in the first text field...it should be
ComboBox with Sequence showing
URL Textbox
Enter Identifyer Textbox
Enter Resource 1 Textbox
Enter Resource 2 Textbox...

"Paste" problem in Combo box...

I have a number of forms with combo boxes in them. These Combo Boxes contain addresses. I want to "add" and "item" to the list.
When I try, it will only let me phsically type the addess into the add item box!
I have a dozen forms I need to add the exact same address to. PLEASE tell me this is some kind of sick joke that you cannot use a *basic* windows convention to "paste" into an input box!!!??? Please tell me that I am missing something very basic here. Adobe was supposed to *save* time, not waste it!
This problem is also compunded by the fact that there is no option to center items entered into the form from the drop-down list! So I have to manually add spaces to get it close to centered. C'mon guys.... where is the justification optin for this?
HELP!

OK, there is a first time for everything....
Seems the computers in question have a little utility installed called "Pure Text". I have used this with no compatibility problems - until now. What it does is provide a key-stroke method for cuting and pasting only the text - so it strips out all formatting.
For whatever reason, this utility does not work with Actobat Standard 9. As soon as I exit the utility (it loads on boot), then pasting works just fine.
I have already e-mailed the Author.
Double checked the "appearance" tab - no alignment options there.
Live & learn! Now it's getting close to lunch... where are those crows...

Adobe Reader app on my ipad air problem with combo boxes filling in

I am using Adobe Reader app on my ipad air and when filling out forms, and making a selection from a combo box, my selection dissappears. Not visible, not printable, not savable, just blank. It works well on my Reader on my Windows desktop. Any ideas?

cas ecowater,
We can examine your PDF forms and determine the cause of the problem.
Would you send the PDF forms as email attachments to [email protected]? Please include the link to this forum post (https://forums.adobe.com/thread/1634405) in your email message for reference.

PROBLEM WITH COMBO BOXES..

HI,
I AM HAVING TWO COMBO BOXES>>
COMBO1------ DEPT NAME
COMBO2------EMPLOYEE NAMES
I AM COLLECTING DATA OF COMBO1 FROM THE DATABASE.....DEPENDING UPON THE FIRST COMBO i.e DEPT NAME...USING THAT DEPT NAME I HAVE TO COLLECT EMPLOYEES NAMES DATA FROM THE DATABASE AND PLACED IN COMBO2 >>....
ANY PLS HELP ME......
I WANT FULL CODE FOR THAT......

You do this by combining JSPs with a central servlet. I don't know how to do it with just one JSP on its own.
The JSP does a <form> POST to the servlet. The servlet fetches the combo box values into a List, puts it into request scope, and forwards the response back to the JSP. The JSP gets the List out of request scope and populates the drop-down. You do the same thing when there's a selection in the drop-down: onChange does a POST back to the servlet, which gets the selected value as a parameter, takes the appropriate action, and forwards the response with new data in request scope back to the JSP.
The trick is to have the data in request scope so the JSP can get it. I think you need a servlet to do that.

Help regarding Combo Box

Hi,
I am trying to create a combo Box at run time.Can anybody tell me how do I get the value the user has selected and then assign it to a EditText. I am doing the coding in C#.

How to get value of html combo box (i.e select) in jsp?

Hello,
I was just wondering how to get value of html combo box in jsp page. My code for combo box is:
<select name="combo" size="1">
<%
List<Project> projects = mgr.getProjects();
for(Project project : projects){
%>
<option value="<%= project.getId()%>"><%= project.getName()%></option>
<%
%>
</select>
I thought combo.value might give me the value, but it throws exception.
Any help is appreciated.
Thanks.

The combo does not exists in Java, but only in HTML. You have to submit the form containing the combo and then use request.getParameter("combo") to get it's value ;-)
