Simple Form Controller and Binding

[rkam]

Hi

We are using SimpleFormController and binding to form bean, there seems to be a problem in the binding when values are duplicated by coma

HTTP header :queryString: name=rk1&base=&profileType=AOR&order=5&preference=10&flags=u

But when the DataBinder is binding for profileType, it is binding values as "AOR,AOR" instead of just "AOR"

Please help..

thanks

Hmmm...just guessing, but I think you are somehow doing a multiple submit and the AOR value is being repeated as a result.

Also, something to check for, make sure in your JSP binding, you are using ${status.value} as below and not ${param.value}.

<spring:bind path="myValue">
<tr>
<td>Enter Value:</td>
<td><input type="text" name="myValue" value="${status.value}" size="30"></td>
</tr>
</spring:bind>

Hi

We are using AJAX call. So we are not using spring:bind .. We are thinking that we are missing some thing. I throwed an exception inside the setXXX()
call to see what is going on.. I see only stack trace .. see below

public void setProfileType(String profileType) {
try
{
System.out.println("ProfileType:" + this.profileType);
this.profileType = profileType;
System.out.println("ProfileType:" + this.profileType);
throw new Exception("Nothing");
}
catch(Exception e)
{
e.printStackTrace();
}

}



StackTrace

ProfileType:null
ProfileType:AOR,AOR
