It looks like I have found an issue with rich:select. Judging by the lack of information on the subject I assume that it's not yet reported.
<f:selectItem itemValue="0" itemLabel="Option 11" />
<f:selectItem itemValue="1" itemLabel="Option 1" />
Given a rich:select
1 - With enableManualInput="true"
2 - With an option that is a substring of another option placed right below the other option (In this example "Option 1" is substring of "Option 11" and is placed below "Option 11"). Note: The exact ordering of options placement is relevant.
Result: We can not chose the subtring option. In this case, when we click "Option 1" the "Option 11" will always be chosen.
The issue occurs in the release we are using (4.3.1.Final) and also in current stable release (4.3.4.Final).
If someone has a workaround for this issue please let me know. If I should open an issue in the bug tracker please let me know also.
Thank you for your assistance.
it is a known bug:
Afaik it should be resolved with RichFaces 4.5 and/or 5. If you wanna use last stable consider using the workaround described in the linked issue.
