Combobox loses it's value if value is entered by user and component is ajax
re-rendered
---------------------------------------------------------------------------------------
Key: RF-5595
URL: https://jira.jboss.org/jira/browse/RF-5595
Project: RichFaces
Issue Type: Bug
Affects Versions: 3.2.2
Environment: Firefox 2 - 3, IE6 / 7, Safari, Opera,....
Reporter: Brian Couchman
When a rich:combobox is on a page, with enableManualInput=true, user can type a
value in the box that is not in the list of propositions.
At that moment, the hidden input is properly populated.
If an ajax request is fired on the page, and the combobox is rerendered, the
input text still contains the user value, but the hidden input is empty, and
any next submit (ajax or not) empties the bean bound to the combobox object.
The issue comes from the renderer of the Combobox
In the class ComboboxRenderer, doEncodeEnd(), at line 560 we see this code :
String hiddenValue = null;
if (items.contains(value)) {
variables.setVariable("hiddenValue", value);
}
which means : "If the value in the field is not part of the list of
propositions, do not fill the hidden input with it". The input text is properly
filled and it breaks the symetry (user sees a value in the box but another
value is saved in the bean).
If enableManualInput=true, meaning the user can type his own value, there
should be no check if the value is in the propositions or not, and the hidden
field should be filled the same way the input text is.
Code should look like :
String hiddenValue = null;
if (enableManualInput || items.contains(value)) {
variables.setVariable("hiddenValue", value);
}
