Subject Re: DynaActionForm problem with non-string objects
Date Thu, 25 Apr 2002 11:41:19 GMT
I think that you'll have to extend the framework. The "initial" value is 
really designed to be a primitive or one of the wrappers around it.  The 
ConvertUtils "convert" method is used and it's not really capable of doing 
what you want it to do. I think you might take a look at extending the 
FormPropertyConfig class, rather than the DynaActionForm. The 
DynaActionForm uses a Map already and should be capable of dealing with 
Objects. It's the initialization portion of the process that you need to 
override and I believe that starts in the FormPropertyConfig class.
