JavaServer Faces - JSF RI 1.2 Duplicate component ID step2Form:j_id9 found in view.
Hi im using JSF RI 1.2 with Facelets
The problem shows when i create a back button :
let say we have pages : step1 and step2 and when im in step2 and click the back button
<h:commandButton action="back" value="#{msg.back}" immediate="true"/>
Then When I TRY to reSubmit the first page (step1) i get this error
maybe becouse the forms are allready added.
i Change the scope of all bean to session the problem is the same
when i submit if the id of the form is allready added i get the exception.
Can i make it more Struts like ? i mean if the id is alrleady created okei grab and get the content of this which is created and put the values in the new one .. dont show me crazy errors ? : )
can i do it ?
The Full Error :
java.lang.IllegalStateException: Duplicate component ID step2Form:j_id9 found in view.

Hmm Somethink New :
I have binded the <h:form with a fields of type HtmlForm in the backingBeans NOW the result is different
when the 3th time the form will be showed then throws the same exception .
example :
from step 1 go to step2 with next.
go back to step1 - lol it works ( this dont works early )
from step1 go to step 2 it works
now from step2 go back to step1 - exception
you can download the example from here :
http://isy-dc.com/~naiden/Wizzard.rar
the Valid data to be added for the first page is :
first feld : 3-8 symbols
secound field 3-8 sumbols
3th field : 8310282400
4 and 5th field must be the same 3-8 symbols
