---------------------------
Summary: Action tag does not process list type parameters correctly
Key: WW-4336
URL: https://issues.apache.org/jira/browse/WW-4336
Project: Struts 2
Issue Type: Bug
Components: Core Actions, Plugin - Tags
Affects Versions: 2.3.15.3
Reporter: Gautham
Hello Everyone.
While migrating application from struts 2.0.11 to 2.3.15.x encountered below
issue -
There is a list of objects available in a jsp, within which an action is
invoked ( using s:action tag ) and that list is passed down for use in the
callee action (this is being done to populate a table). This approach worked
with struts 2.0.11, but with 2.3.15 - the list is being converted to string
first before being passed to the callee action and is unusable by the time its
received.
With some debugging, figured out this piece of code was doing the conversion to
string..
ActionComponent.createParametersForContext()
String key = (String) entry.getKey();
Object val = entry.getValue();
if (val.getClass().isArray() && String.class ==
val.getClass().getComponentType()) {
params.put(key, (String[])val);
} else {
params.put(key, new String[]{val.toString()});
}
relevant code snippet in jsp looks like this
<s:action name="someAction2" executeResult="true" namespace="/common" >
<s:param name="iterable" value="#iter"/>
Is this an intended change in behavior ? I couldn't find relevant details in
the release notes or the migration guide. What's the recommended approach to
migrate such components ?
