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?
