Session state protection violation:

NelsonMendesJul 5 2016 — edited Jul 6 2016

Hi,


Im getting this error when I move from tab to tab...


Session state protection violation: This may be caused by manual alteration of protected page item P0_FIELD.

If you are unsure what caused this error, please contact the application administrator for assistance.


The filed is in global page.

Can you point me some directions please?


APEX 4.2.5


Thanks,

Is there a way to debug this?

NelsonMendes

Anyone please, this is urgent...

Thanks

It is 4.2.5 if it is 5.0 we could help you by debugging for you on apex.oracle.com to find a solution ASAP.

Could you print screen all the settings of P0_FIELD

P0 not P0_FIELD in your screenshots !!

NelsonMendes

Sorry it was a typo, its P0 and autocomplete field

PMON

Try taking a look at this thread and checking for a p_page_checksum item and it's position relative to form tags in your page...

Page protection violation on APEX 4.1.1.00.23

Hope this helps

Hi badjaras

Change the type of P0 to be Display Only

For all practical purposes, this is really an item of type Display Only with "Save Session State" of "No"

Reference

Session state protection violation

Please take a look at this

Security - Oracle APEX Best Practices - page 176

I hope that solves your problem

Hi Mahmoud,

Thank you for your reply.

If I change the item to Display Only with "Save Session State" of "No" it works.


But that can not be... Is this a good signal?

Can it help me to debug the error?


Thanks,

NelsonMendes

Hi all,

Ive found that the app item in "Source Value or Expression" is raising this issue, my question is why?

Thanks,
