> Key: SHINDIG-1465
> URL: https://issues.apache.org/jira/browse/SHINDIG-1465
> Project: Shindig
> Issue Type: Bug
> Components: Java
> Affects Versions: 2.5.0-beta1
> Reporter: Kai Feng Zhang
> Fix For: 2.5.0-beta1

> Attachments: userPrefs_20101108.patch
>
>
> When using new common container to render gadget, the ifr request url will be
> from gadget metadata request. At the back end, method makeRenderingUri()
> will be called on DefaultIframeUriManager class to generate the ifr url. In
> this method, there are following code snippet to add default user prefs into
> url.
> // Add all UserPrefs
> UserPrefs prefs = context.getUserPrefs();
> for (UserPref up : gadget.getSpec().getUserPrefs().values()) {
> String name = up.getName();
> String data = prefs.getPref(name);
> if (data == null) {
> data = up.getDefaultValue();
> }
> boolean upInFragment = !view.needsUserPrefSubstitution();
> addParam(uri, UriCommon.USER_PREF_PREFIX + up.getName(), data, useTpl,
> upInFragment);
> }
> Such as if gadget spec xml defined a pref named "mycolor" with default value
> "Green", but the addParam method will change the "mycolor" value to
> "%up_mycolor%" because useTpl is true. Thus, ifr url will be requested with
> all invalid user prefs values. And when you try to get some default value
> from user prefs, it return invalid value.
