J G commented on STS-555:
-------------------------
Thanks Scott and Kai,
I have followed Kai's idea, overriding getSourcePageResolution and
setSourcePageResolution in my own ActionBeanContext. And in my ActionBean I
have overriden setContext and getContext. It seems ok when I tried to debug.
But the errors are not showing up in the browser. I am wondering if this got to
do with Ajax updating the UI or a browser problem perhaps..?
I even tried to debug the normal flow that does not use Ajax .. for example
coming from a click of a submit button implemented in Stripes and having known
errors in the form. The sequence of events/flows is the same with the Ajax way
of submitting.
Then for Scott's comment, I have done that one like overriding
getSourcePage and having a catch Exception just to catch CryptoUtil's exception
and just returning the un-encrypted source page if it have thrown an exception.
But still the same thing happens.
I wonder if anyone have experienced doing Ajax together with Stripes and if
they have resolved a similar problem that I am encountering.
Thanks,
J G
