Chris Cranford commented on WW-4066:
------------------------------------
bq. If you take a look on paramsPrepareParamsStack you will spot that the
params interceptor is listed two times - before and after prepare, but there is
also modelDriven listed just before the second params which will put non-null
Model onto stack.
I don't recall specifically why the interceptor stack was designed that way
beyond perhaps being backward compatible. I recall a discussion sometime back
where it was decided that the interceptor stack would be designed this way.
I just applied 2.3.4.1 to the sample application and with devMode=true, I do
see where the OGNL exceptions are written to the logs, perhaps I had overlooked
them prior. What boggles me however, is that StringIndexOutOfBoundsException
isn't thrown as a side affect. And the stack trace related to that exception
is coming from {{LocalizedTextUtil}}. Why is that just now surfacing but not
in prior builds?

> Our BaseAction which extends ActionSupport overrides the addActionMessage()
> with the following:
> {code:java}
> @Override
> public void addActionMessage(String message) {
> super.addActionMessage(getText(message));
> }
> {code}
> With the above method in place during devMode=true, the following error stack
> trace occurs:
> {noformat}
> java.lang.StringIndexOutOfBoundsException: String index out of range: -1
> at java.lang.String.substring(String.java:1871)
