How to Validate the Text Field in JSF

Hi,
I am facing a issue to validate the text field where the below code accepts (space' ',underscore'_',pipe'|') symbol as a first character and last character.Where by it can accept in the middle.
It should not accept special characters also. Below code is working properly for special characters.
<tr>
<td width="30%" align="right"><h:outputText id="aAccrualType" value="Accrual Type" /> *</td>
<td width="50%">: <h:inputText id="accrualType" value="#{accrualTypeMast.accrualType}" required="true" >
<t:validateRegExpr pattern="^[(a-z)||(A-Z)||(0-9)||(_)||(\s)||(/)]+$" />
<f:validateLength minimum="1" maximum="50"/>
</h:inputText>
<h:message for="accrualType" showDetail="true" style="color:red" />
</td>
</tr>
The thing is i dont have much knowledge in regular expression.
Is there any other way to do this.
Could anyone help me in this.
Thanks,
Ambika☺

This has nothing to do with JSF.
I suggest you to read the Pattern API documentation [1]. You can easily create a small Java Application and test the regexp using String#matches() as it uses the same regexp guidelines.
public static void main(String[] args) {
 String regexp = "^[a-z]+$";
 String value = "foo";
 boolean match = value.matches(regexp);
 System.out.println(value + " matches " + regexp + ": " + match);
}[1] http://java.sun.com/j2se/1.5.0/docs/api/java/util/regex/Pattern.html

How to validate a text field??

Can any one tell me hot to validate a text field??
I want to create a text field which holds alphabets only..

You can use simple javascript code in the liveChange function such as the following (for sap.m.Input):
liveChange: function(evt) {
var inputValue = evt.getSource().getValue();
this.setValueState(me.validateTagName(inputValue));
 this.validateTagName = function(inputValue) {
 if (inputValue.trim().length < 1) {
 return "Error";
 } else {
 return "None";

How to insert more than 12 items using BDC for MB1C

Hi,
When we use LSMW for data transfer of MB1C transaction, more than 12 items can be inserted in a document.
But using BDC only 12 and below is possible, if the flat file system has more that 12 item, then the document is not created.

How to get the text field in the header for only first page of the report

Hi,
I am developing reports in BI Publisher Enterprise where i am facing problem i.e., i have to get some text field in header,for only first page in the result but it is displaying in all the other pages of the report in result.So,please if you have any idea of how to solve it, please reply.It is required as early as possible.
Thanks in Advance

Invalid path? What are you doing? Writing the report output to an invalid directory?
Where are your terms and conditions? It would be very easy just to put them in a database table and select them in your report query.

How to validate empty Text Field?

Hi,
I am Thirupathi,
I am new to JSF. I am able to validate the value of a component which has some value using attribute
validator="#{UserNumberBean.validate}"
in this case it is calling validate method of UserNumberBean.
but if i keep the field empty then it is not calling that validate method of UserNumberBean.
Please can any one clarify my doubt.
wait for reply
Thanx in advance.
Thirupathi Reddy
mail Id: [email protected]

validate method is called to validate the correctness of the value input by user (eg. email format, phone numebr etc.). If user leaves the input box empty then there is nothing to validate and so validate is not called.
If you want customised messages for required fields you can use requiredMessage attribute in your inputText tag provide that you are using JSF1.2. It is not available in JSF1.1. In JSF1.1 it is requires some extra coding. You can do like this :
In your managed bean
public class MyBean {
 private String userName = "";
 private String password = "";
 private ArrayList errors = new ArrayList();
 public String getErrors() {
 String message;
 if (errors.size() == 0) {
 message = "";
 } else {
 message = "<UL>\n";
 for(int i=0; i<errors.size(); i++) {
 message = message + "<LI>" +
 (String)errors.get(i) + "\n";
 message = message + "</UL>\n";
 return(message);
 public String validateUser() {
 errors.clear();
 if (userName == null || userName.trim().length() == 0) {
 errors.add("User Name is required");
 if (password == null || password.trim().length() == 0) {
 errors.add("password is required");
 if (errors.size() > 0) {
 return(null);
 } else {
 //perform your logic here
 return("returnString");
}In your jsp page, include the errors tag as below. It will show all errors on top of the page.
<f:view>
 <h:form>
 <h:outputText value="#{MyBean.errors}" escape="false"/>
 User Name: <h:inputText value="#{MyBean.userName}" />
 Password: <h:inputText value="#{UserBean.password}" />
 <h:commandButton value="Login" action="#{UserBean.validateUser}" />
 </h:form>
 </f:view>One point to remember is to clear the errors List in every action.
Hope it helps.

Indesign Scripting: How can I move a placed item using Javascript?

Hey all,
I have been trying to write a script that places a slug object from an indesign library on to a document and then moves it to my slug area. It all seems to work except the move command. I think the problem is that I haven't selected my placed asset correctly.
Please help!
This is what I have so far:
//Create new document
var doc = app.documents.add();
// Get page size values
var w = doc.documentPreferences.pageWidth;
var h = doc.documentPreferences.pageHeight;
//Create layer called SLUG
var slugLayer = doc.layers.add({name:"SLUG"});
//Set document slug area size
doc.documentPreferences.documentSlugUniformSize = false;
doc.documentPreferences.slugBottomOffset = "20 mm";
//Open InDesign library file that contains the slug file
var slugLibrary = app.open(File("/Users/Shared/Slug.indl"));
//Place slug script to go here
var myPlacedAsset = slugLibrary.assets.item("Slug");
var mySlug = myPlacedAsset.placeAsset(doc);
//Close the slug library
slugLibrary.close();
// Move slug object to slug area
mySlug.move([0,0]);
//Lock SLUG layer
slugLayer.locked = true;

placeAsset is an array so this line : mySlug.move([0,0]);
should be changed to: mySlug[0].move([0,0]);

How do I edit a field so that it accepts numbers only?

I've seen java scripts posted and none of them have worked for me. Perhaps it's that I'm not sure exactly how or sure where to enter the script, or which script to use. I've also tried using the arbitrary mask feature and entered 9 in the box, but the form still accepts letters in Reader. Help please!

What kind of form are you referring to? Are you trying to use Adobe Contribute or something else? It's hard to tell what's up from your question. Sounds like you are using Adobe Acrobat or something.

How to hide text field item based on true or false cases in oracle apex

Hi,
I have a set of text Field items in oracle apex:
Order Number
Revision Number
When we open the report, revision should be hidden.
Only when the user enters unique order number (non-duplicate order numbers), revision number should be visible.
If he enters duplicate order number, revision number should be hidden.
Please help.

Please help.
Giving you example how to achieve this.
Step 1. Create three Page Items
    1) P1_ORDER_NO - Text Field
    2) P1_REVISION_NO - Text Field
    3) P1_ENABLE_DISABLE_REVNO - Hidden,Value Protected - No
2. Create 3 Dynamic Actions
1) Disable revision number on page load
    Event - Page Load
    Action - Disable
    Fire When Event Result Is - True
    Selection Type - Item
    Item - P1_REVISION_NO
2) Check duplicate order number
    Event - Change
    Selection Type - Item(s)
    Item(s) - P1_ORDER_NO
    Condition - is not null
    Action - Execute PL/SQL Code
    Generate opposite false action - Unchecked
    Fire When Event Result Is - True
    Fire on page load - Unchecked
    Stop Execution On Error - Checked
    Wait for Result - Checked
    PL/SQL Code -
declare
l_count number;
begin
select count(*) into l_count
    from emp
   where empno = :P1_ORDER_NO;
if l_count > 0 then
:P1_ENABLE_DISABLE_REVNO := 1;
else
:P1_ENABLE_DISABLE_REVNO := 0;
end if;
end;
Page Items to Submit = P1_ORDER_NO
Page Items to Return = P1_ENABLE_DISABLE_REVNO
3 ) Enable and Disable Revision Number
    Event - Change
    Selection Type - Item(s)
    Item(s) - P1_ENABLE_DISABLE_REVNO
   condition - greater than or equal to
   value - 1
   Action - Disable
   Fire on Page Laod - Unchecked
   Generate opposite false action - checked
   Selection Type = Item(s)
   Item(s) - P1_REVISION_NO
Hope this helps you,
Regards,

How to add new text field in standard report

how to add new text field in standard report?

Hi,
I presume you are talking about a report display in ALV and u wish to add a column to it .
If it is a global requirement ,as in table being used there in ALV can be modified, then you can append the table and the system should pick up the same automatically from there.
Otherwise , you can make a Z program . Modify the catalog being used in ALV.

How to populate the TEXT field in MIGO

Hi folks,
While creating material document in MIGO or MB01, i am inserting some data in TEXT ( Field in line item level ). This text data is disappearing , once mat doc is created.
how to populate the TEXT field in MIGO?Is there any cusomisation?it's urgent .
Regards
pabi

Hello Pabitra,
I had a similar issue in my Project.
Please verify if the SMOD enhancement MBCF0002 (EXIT_SAPMM07M_001) is active in your system.
If this is the case, verify from two angles:
a) Whether the Enhancement was accidentally activated - If yes, then De-activate the same
b) If there is some logic coded in the User Exit, but, the Text is somehow not determined...even the existing content in the text field (input to EXIT_SAPMM07M_001) will get vanished.
Hope that your problem will be resolved by this. Pls reward points.
With Regards
Vijay Gajavalli

How to collapse unused text field in PDF form

How can I expand text fields in my PDF file which I built in Forms Central?

I'm working in Windows 7 and just created my first form in Forms Central. I have many text fields that I intended for the end user to be able to type as much information in them as necessary. I selected the "multiple lines of text" setting for each of these fields. I was told by someone at Adobe a while back when I was trying to decide on learning LiveCycle Designer or using the much more user-friendly Forms Central that the form fields would not automatically expand in the PDF form, but that I would be able to click or drag on the fields manually to expand them so that, ultimately, they could be printed with all the comments, for however many pages it would take. I've exported my Forms Central form to a PDF file. However, when I type multiple lines of text in the form fields I set up to be "unlimited," I cannot get the form fields to expand. What have I done wrong? Help, please!

We are dealing with a similar situation. We have downloaded LiveCycle and created the form, but as we knew would happen, the changes that come for the content of the form are causing us to max our trial version, and as soon as the form needs a change outside of the trial time period, we are faced with the next dilemma, as Adobe doesn't offer to purchase a single license at a reasonable rate. The only reason we wanted LiveCycle was for the dynamic field feature. I plead with you to consider offering that feature in Forms Central. The other issue that we are having is that our users sometimes need to paste a table into the expandable text field. Is that even possible in Live Cycle? We don't at this point need the web-based functioning that Live Cycle offers. Thank you.

How to show a text field based on what is entered in a date field

Hi there LiveCycle experts!
I have a form with a text field that I want to show only if the value of the previous date field once entered is less than 1 month from today?
Any help appreciated, been researching in vain for hours!!!
Sarah

Wow Steve - thanks so much this is so exciting I just love learning these new scripts.
I assume I need to make the text field 'Hidden' - ?
I seem to be struggling a little to get it working - are you able to have a quick squizz at my document - it is in the very early stages!
