picklist problem with complex data types ---------------------------------------- Key: RF-9796 URL: https://jira.jboss.org/browse/RF-9796 Project: RichFaces Issue Type: Bug Security Level: Public(Everyone can see) Components: component Affects Versions: 3.3.3.Final Environment: -RichFaces 3.3.3Final -JSF1.2 -Facelets 1.1.1B1 -GateIn Portal 3.0 Reporter: Andrew Cheung Assignee: Nick Belaevski Fix For: Future_3.X I got an "index out of range: -1" error message in the log when I tried to use complex data type for the items in a picklist. The code in various files and the error log are as follows: ------------------------------------ regionresults.xhtml: <rich:pickList id="plRegions" showButtonsLabel="false" copyAllVisible="false"

08:04:15,162 INFO [STDOUT] (http-127.0.0.1-8080-1) SampleFilter end of the 'rlpportal' Note: I realized that only the item that is originally on the right hand side (i.e. the item with the label "existing region" if you refer to the code I posted in my original post) is an instance of the RegionItemBean when getAsString is called. (The item that I picked from the left hand side returns null when getAs String is called). I have posted this to the forum and the user "Ilya Shaikovsky" suggested me to report this problem.
