Conversion error occured

conversion error occured while using h:selectmanyListbox tag.

Have the exact same problem, am using Rational Application Developer 6 (WSAD 6) in combination with websphere 6. I have a datatable (server side component) which is based on a javabean collection. The javabean has an Integer attribute "id". I'm presenting the "id" as a hidden field which works fine. when I submit the form containing the table I want to bind the hidden field to a requestScope variable. But before it hits my code I already get the table:0:hidden1: Conversion error occured.
Have tried without converter, with numberConverter and a Custom convertor (which is called and works correctly (as in it doesn't generate the Conversion error)).
So the conversion error is generated after my own custom convertor is called. Which part of the JSF code has to convert the field after mine is done ???
And I'm also doing this on 1 page (maybe that's something to look at....)

A conversion error occurred while the program -- display data on the screen

HI all,
Iam getting a dump error described below:
A conversion error occurred while the program was trying to
display data on the screen.
The ABAP output field and the screen field may not have the
same format.
Some field types require more characters on the screen than
in the ABAP program. For example, a date field on a screen needs
two characters more than it would in the program. When attempting to
display the date on the screen, an error will occur that triggers the
error message.
              Screen name.............. " Ztable_MM_MRQ "
              Screen number............ 0100
              Screen field............. "WA_PO_ITEMS-MENGE"
              Error text............... "FX015: Sign lost."
Further data:
Give us step by step procedure to rectify the same with T.codes

"Conversion error occurred." at f:convertDateTime pattern="dd/MMM/yyyy" /

This is my jsf code.
<h:inputText id="myDatePicker" value="#{backingBean.user.birthDate}">
<f:convertDateTime pattern="dd/MMM/yyyy" />
 <hx:inputHelperDatePicker />
 <hx:inputHelperAssist promptCharacter="x"/> <hx:validateDateTimeRange maximum="#{now}" />
 </h:inputText>
When I click the button to call action backing bean, I get the "Conversion error occurred".
I've already instantiate the birthDate in constructor of User class.
I just wonder this tag apply for Date only? Because the type of birthDate attribute is Timestamp.
Thank you for you reply and any suggestion.

I use the date picker of WebSphere product.
<%@ taglib uri="http://www.ibm.com/jsf/html_extended" prefix="hx"%>
I try to remove value from this but it still not work.
Can anyone help me or need me to give more information ?
Thank you!!

Problem h:SelectManyCHeckbox --Conversion error occured

Need urgent help ,Causing a lot of trouble
error--
com.sun.faces.context.FacesContextImpl addMessage Adding Message[sourceId=formUserSetup:chkboxUserPrfRoles,summary=Conversion error occurred)
Displays the form fields depending on the selected value on the select one list box.select many check boxes displays the values of the check boxes for the selected user.Everything is working fine for the first display
For the secong selection its throwing an error.
code:
onchange:
f = document.getElementById("formUserSetup");
f.submit();

Thank u,
yes ,value in the select one list box is ties toa string .Depending on the slected string i am generating a information bean that displays and binds to the form.
I n this form i have got a select many checkbox control that displays
--all the roles in table
--and the value will have roles belonging to a selected user from the list box control
In this process when i switch b/w the users there is a conversion error

Conversion error occurs in all the command button actions

we have two h:commandButton (save and back) in a jsf form.
If i click the save button conversion for the form fields should happen(its happening correctly).
But if i click the back button it should directly take me to the backing bean's action method without any conversion so that i can avoid the conversion errors.
Is there any solution or work around to achieve this.
Thanks,

<h:commandButton value="save" action="#{MyBean.save}"/>
<h:commandButton value="back" action="#{MyBean.back}"/>
but in our case, during the back action method we need the bean value(id="str") for calculation but we don't want conversion to be happened for calendar field. if we use immediate attribute for back button we will not get the bean value(id="str") in the action method. is there any alternate solution to this.I cannot think of a standard technique to handle this case, where some of the data is needed but other data should be ignored. You might try to grab the value from the request parameter map and manually assign it to the model (this work around doesn't scale however).
Perhaps what might work is to have a valueChangeListener on the fields which will be preserved; I think they will be fired even with the immediate attribute.
I do not think the <f:attribute> solution suggested will work as attributes are server side artifacts.

Conversion error in write access to a property

Hello,
in JSF I get a conversion error when I try to save an order.
An order object has a from- and a to-address.
To avoid duplicate coding I encapsulated the address data in a class Address.
public class Order implements Serializable{
private Address fromAddress;
private Address toAddress;
//Getter/Setter for addresses are implemented
public class Address implements Serializable{
private String city;
private String country;
private String remark;
//Getter/Setter for all fields are implemented
}Reading the address data works without problems.
Writing (saving an order) does not work. For each property of Address a conversion error is thrown.
The access is like
<t:inputText value="#{orderBean.order.address.country}" .../>
Principally it is possible to access the address properties because reading works.
What is going wrong when writing?
And how could I find out more details about the conversion errors occurred?
Any hints appreciated

I'm afraid these are the fileds causing the errors.

Conversion error in checkboxgroup component.....

hi
i have a checkboxgroup component. first time when i go this particular page no validation error occurs. but when i go to a different page and return back conversion error occurs in that component.
getSubmittedValue() method for that component returns some value when error occurs.
can anyone give some suggestions to resolve the error. or suggestions on the value to be converted for checkboxgroup

the actual code is
<cg:checkboxGroup binding="#{view$UsersSMSReport.action_chkbxgrp}" columns="1" id="action_chkbxgrp" style="width: 100%;"/>
<cg:message binding="#{view$UsersSMSReport.action_msg}" for="action_chkbxgrp" id="action_msg"/>
where cg is the our own tag discriptor file
we use jsp-api.jar and jstl.jar for customization of components.
the taglib file for this tag refers to class
CGCheckboxGroupTag extends UIComponentTag
the setProperties method in above class contains code for convertor
if(converter != null)
if(isValueReference(converter))
javax.faces.el.ValueBinding _vb = getFacesContext().getApplication().createValueBinding(converter);
component.setValueBinding("converter", vb);
} else
javax.faces.convert.Converter _converter = FacesContext.getCurrentInstance().getApplication().createConverter(converter);
component.getAttributes().put("converter", converter);
the design time class for this component is
CGCheckboxGroupBeanInfoBase extends SimpleBeanInfo
they are compiled into a tld file and added as complib file in project
the same component sometimes i get conversion error in validation phase and sometimes i get error in page displaying
java.lang.NullPointerException
ClassName:com.sun.rave.web.ui.util.ConversionUtilities
FileName ConversionUtilities.java
MethodName: convertValueToArray

Conversion error in company code currency for general costs activity

PS Experts,
Please guide me in the following , The below message appeared when i created a customer project in CJ20N in our new DEV server
This is the scenario
Create customer project with 3 WBSE, each one has 3 NTW and 3 activities, i maintained the cost with currency same as project curr and company code currency in the first two act.
in the third activity (General act) in cost tab i put a currency is different than project currency& company code currency and tried to save the project, the message appears.
note: Company code curr same as projet curr & controlling area curr
Is there any setting is missing in customizing
Conversion error in company code currency for general costs activity 0010
Message no. CK443
Diagnosis
For cost activity 0010, a conversion error occurred in the currency of the company code to which the material is assigned.
Procedure
Check the global settings in Customizing to be sure the exchange rate for conversion into the company code currency is correct
Thanks

Hi Yassin,
I believe you have maintained exchange rates for rate type M as per your config in OPSB.
Now do one thing, maintain the conversion rate for P for those currencies in OB08 and then save your project.
This will solve your problem.

Kabir

Conversion error, from character set 4102 to character set 4103

Hi,
We've developed a JCO server(in Java) with an ABAP report the function provided by the JCO server.
MetaData:
     static {
          repository = new Repository("SMSRepository");
          fmeta = new JCO.MetaData("ZSMSSEND");
          fmeta.addInfo("TO", JCO.TYPE_CHAR, 255,   0, 0, JCO.IMPORT_PARAMETER, null);
          fmeta.addInfo("CONTENT", JCO.TYPE_CHAR, 255,   0, 0, JCO.IMPORT_PARAMETER, null);
          fmeta.addInfo("RETN", JCO.TYPE_CHAR, 255,   0, 0, JCO.EXPORT_PARAMETER, null);
          repository.addFunctionInterfaceToCache(fmeta);
Server parameters:
       Properties prop = new Properties();
       prop.put("jco.server.gwhost","shaw2k07");
       prop.put("jco.server.gwserv","sapgw01");
       prop.put("jco.server.progid","JCOSERVER01");
       prop.put("jco.server.unicode","1");
       srv = new SMSServer(prop,repository);
If we run JCO server in both my client machine(from developer studio) and in the WAS machine(stand alone Java program), everything is ok. In the Abap side, the SM59 unicode test return the destination is an unicode system, and the ABAP report call the function can run smoothly.
But we package this JCO server to a web application and deploy to WAS, problem occured. The SM59 unicode test still say the destination is an unicode system. But the ABAP report runs with an ABAP DUMP:
Conversion error between two character set
RFC_CONVERSION_FIELD
Conversion error "RETN" from character set 4102 to character set 4103
A conversion error occurred during the execution of a Remote Function
Call. This happened either when the data was received or when it was
sent. The latter case can only occur if the data is sent from a Unicode
system to a non-Unicode system.
I read the jrfc.trc log, it shows it receives data in unicode 4103(that's ok), but send data in unicode 4102(that's the problem).4102 is UTF-16 Big Endian and 4103 UTF-16 Little Endian. Our system is windows on intel 32 aritechture, so based on Note 552464, it should be 4103.
Why it sends data (Java JCO server send output parameter to ABAP) in 4102?????
What's the problem??? Thank you very much!!

Date field - no date entered - conversion error

Hi,
i've a input text field with a datepattern attached in my jsp, whose requrired attribute is set to false. If i submit the page and no date is entered, JSF returns "Conversion error occured" for the date field.
For testing purposes i made a simple JSP which contains only this date field and a reload button, which only submits the form. When the button is clicked the conversion error is displayed as described.
What am i doing wrong here?

JSF Conversion error for h:selectManyListbox

There's an exception (*Conversion error occurred*) from JSF on <h:selectManyListbox> component for id availableUsers which is bound to myBean*.*roleId

Error named like "CONVERSION ERROR"

I am creating one Module Pool Program with the Screen Painter. There is total 10 Tab Strips used in the Screen Painter.
When I select the Last Tab, I get the Error with the message " CONVERSION ERROR"
Can you guide me why this error can occurs?

Hi,
Check whether you are entering false values in a field which is not belong to that type.
For example, if you enter characteristic value into a numeric field and doing arithmatic operations.
CONVERSION ERROR occurs in this case.
Please check for above.

Conversion Error of SelectManyCheckBox

Hi @ all,
I need your help urgently!
I want to realize two SelectManyCheckBox, each of them has a valueChangeListener. When user change the current state of the check boxes, some actions are performed.
The problem now is when one check box is clicked(a valueChangeListener is called), then a conversion error message is shown out, which says there is a conversion error occured at the other SelectManyCheckBox component.
I tried several times and found, only if the presious state of the check box component is empty, such conversion error occurs.
The codes are like following:
 <TD>
 <h:selectManyCheckbox value="#{admin.filterSelection1}" id="filter1" immediate="true"
 valueChangeListener="#{admin.firstFilter}" onchange="submit()">
 <f:selectItems value="#{admin.filters1}"/>
 </h:selectManyCheckbox>
 </TD>
 <TD>
 <h:selectManyCheckbox value="#{admin.filterSelection2}" id="filter2" immediate="true"
 valueChangeListener="#{admin.secondFilter}" onchange="submit()">
 <f:selectItems value="#{admin.filters2}"/>
 </h:selectManyCheckbox>
 </TD>..............
and the corresponding properties in the backing bean are:
 private ArrayList filterSelection1;
 private ArrayList filterSelection2;
 private SelectItem[] filters1;
 private SelectItem[] filters2;in the constructor of the backing bean, i initialized filters1, filters2 also filterSelection1 and filterSelection2. And their set , get methods are generated by eclipse automatically.
Waiting for your answers......
Finally I wish the person, who replied, a happier Christmas, and the person who does not replied, a happy Christmas. :-)
db

thanks for your reply, but i think my problem is not what you meant.
I changed my code a little bit, the conversion error remains......
 <TD>
 <h:selectOneRadio value="#{admin.filterSelection1}" id="filter1" layout="pageDirection"
 valueChangeListener="#{admin.firstFilter}" immediate="true" onchange="submit()">
 <f:selectItem itemValue="studenten" itemLabel="Nur Studenten" />
 <f:selectItem itemValue="mitarbeiter" itemLabel="Nur Mitarbeiter" />
 <f:selectItem itemValue="alle" itemLabel="Alle" />
 <f:selectItem itemValue="selectAll" itemLabel="Alle an/aus" />
 </h:selectOneRadio>
 </TD>
 <TD>
 <h:selectOneRadio value="#{admin.filterSelection2}" id="filter2" layout="pageDirection"
 valueChangeListener="#{admin.secondFilter}" immediate="true" onchange="submit()">
 <f:selectItem itemValue="intern" itemLabel="Nur Intern" />
 <f:selectItem itemValue="ausser" itemLabel="Nur Auftr�ge" />
 <f:selectItem itemValue="alle" itemLabel="Alle" />
 <f:selectItem itemValue="selectAll" itemLabel="Alle an/aus" />
 </h:selectOneRadio>
 </TD>........................
 private String filterSelection1;
 private String filterSelection2;Beside that, I can not understand why even I set "immediate" property be "true", the set method is stilled called!!!!
