Lukasz Lenart updated WW-3455:
------------------------------
Fix Version/s: 2.3.x
> ServletRedirectResult ignoring supressEmptyParameters option
> ------------------------------------------------------------
>
> Key: WW-3455
> URL: https://issues.apache.org/jira/browse/WW-3455
> Project: Struts 2
> Issue Type: Bug
> Affects Versions: 2.1.8.1
> Reporter: Thomas Howard
> Fix For: 2.3.x
>
>
> I've been attempting to use the supressEmptyParameters option on
> ServletRedirectResult but it appears that this option is basically ignored in
> the code.
> Looking at the source it seems there's a line that adds the value to the
> requestParameters map:
> requestParameters.put(e.getKey().toString(),
> e.getValue() == null ? "" :
>
> conditionalParse(e.getValue().toString(), invocation));
> Which is then followed by the check of the empty parameters, which then
> attempts to add the value again:
> String potentialValue = e.getValue() == null ? "" :
> conditionalParse(e.getValue().toString(), invocation);
> if (!supressEmptyParameters || ((potentialValue !=
> null) && (potentialValue.length() > 0))) {
> requestParameters.put(e.getKey().toString(),
> potentialValue);
> }
> I'm guessing that the first line was either left in by mistake, or maybe got
> merged back into place by mistake, but basically needs to be removed.
> Thanks
