Subject [jira] Created: (SHALE-216) possibility to "skip" token validation when necessary
Date Tue, 11 Jul 2006 09:43:16 GMT
possibility to "skip" token validation when necessary
-----------------------------------------------------

         Key: SHALE-216
         URL: http://issues.apache.org/struts/browse/SHALE-216
     Project: Shale
        Type: Improvement

  Components: Core  
    Versions: Nightly    
 Environment: Myfaces 1.1.2
    Reporter: Veit Guna


I'm using the shale token tag to avoid duplicate form submits. It works so far.

Now I have this usecase:

- An input form is generated with fields for an address (street, areacode, city etc.)
- The token tag is placed in the bottom of the form to avoid re-submit
- There are some validators in the form, that validate areacode in combination with city
- Is the city not unique when submitting, a warning msg is added to the facescontext and the
possible cities are presented in a selectbox to choose from (javascript auto-submit)
- After choosing the right city (the form is submitted automatically by JS), another check
looks for multiple areacodes for that city and displays them in another selectbox with an
additional msg in the facescontext that the user has to select one.
- When the user selects the areacode (JS auto-submit), the form is re-displayed without any
msg (because, everything is fine now)
- Here is the problem: re-displaying the page without an queued error msg in the facescontext
will mark the form "as-sent".
- So finally when the user wants to submit the form (after correcting his input), the tag
doesn't allow sending the form again.

It would be nice, if it would be possible to "skip" a validation for the token for re-displaying
a page or to generate a new token when re-displaying without
validation errors.

One "solution" would be to add an additional msg to the facescontext, when validation of areacode+city
is finally ok. But perhaps the component could offer a solution to this?
