disabling netui:select tag with client side Javascript can cause an exception
-----------------------------------------------------------------------------
Key: BEEHIVE-1193
URL: https://issues.apache.org/jira/browse/BEEHIVE-1193
Project: Beehive
Issue Type: Bug
Affects Versions: 1.0.2, 1.0.1
Reporter: Carlin Rogers
Assigned To: Carlin Rogers
Fix For: V.Next
An ArrayIndexOutOfBoundsException (or an AssertionError with asserts on) is
thrown when client side Javascript disables the generated HTML select tag just
before the form is submitted. The problem with this is that the additional
hidden input element, <input type="hidden" ...>, used by the framework,
provides form data that normally is not be present when the form is disabled
via the NetUI tag attribute.
This hidden element is used by the framework and its name includes a special
marker. So when the Javascript disables the select element, there is still a
hidden <input> that gets processed. During the parameter processing the
frameworks sees the input and determines that there should be select data to go
with it but in this case there isn't because the Javascript disabled the select.
Need to make sure that parameter processing in the Select.SelectPrefixHandler
class can handle this case correctly and treat as a null parameter value.
The stack trace for this issue is...
