<div class="jive-rendered-content"><p>I am in a bind in a big way because this problem seems so obscure. I began developing an application using Spring and IceFaces a few weeks ago. I wasn't having any of the issues that I am over the last few days trying to convert to RichFaces.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Of course all of the backing Spring bean classes were moved right over. The proper adjustments were made in the web.xml file.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Upon running may application I see a blank form with all of the drop down lists populated as expected. I put a break point in a custom converter for one of the drop downs. I put this breakpoint on the getAsString method. This method does not involved the @Autowired  property, but I can see the Spring correctly injected its value from within the debugger. All is good!!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>On the subsequent view I retrieve a row from the database. There are quite a few @Autowired properties that have been injected just fine. In the debugger I now have a breakpoint on the getAsObject method. Once the debugger stops there my @Autowired property that is nedded in this method is null.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I cannot for the life of me see how moving to Richfaces could cause such a disaster, but I can't find anything thing else and am at my wits end!! I desperately want to move to RichFaces, but am in one hell of a bind!!!!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Please help!!!</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Here is the custom converter bean:</p><p style="min-height: 8pt;
