Re: zoning out on some basic LazyDynaMap usage for a text field property?
Thanks Martin, I'll have to look at this.
For now I just went back to using the Session. My form was going to need to
nest maps of maps to N levels. And the values that could be set for some of
the maps could be a String[] or List[]. I got fed up trying to figure out
how to get this to play nice using request scope.
I'm going to look at how other frameworks (maybe even Struts2) handle these
nested item issues with backing beans using Request scope. (I happen to be a
fan of Stripes but haven't looked at how they manage this behind the scenes
either because I'm swamped with work.)

Since Struts 1.1, the reset method no longer initializes property values to
those specified in elements in the Struts module
configuration file. If you wish to utilize that behavior, the simplest
solution is to subclass DynaActionForm and call the initialize method inside
it.
1)setup FormBeanConfig supplying name and type
http://struts.apache.org/1.2.7/api/org/apache/struts/config/FormBeanConfig.h
tml
beanconfig.setName("name");
and then beanConfig.setType("org.apache.struts.action.DynaActionForm");
2)// Construct a corresponding DynaActionFormClass
http://struts.apache.org/1.2.7/api/org/apache/struts/action/DynaActionFormCl
ass.html
dynaClass = new DynaActionFormClass(beanConfig);
constructing the DynaActionForm for FormBeanConfig class
3)2 ways to initialize DynaActionForm
Initialize your DynaActionForm is with FormBeanConfig if you have a
of struts-config file
http://struts.apache.org/1.2.7/api/org/apache/struts/action/DynaActionForm.h
tml#initialize(org.apache.struts.config.FormBeanConfig)
the other initialize method assumes you are initializing properties from
of struts-config file
http://struts.apache.org/1.2.7/api/org/apache/struts/action/ActionMapping.ht

Don't feel like writing > a > reset method? Unless I'm missing something, the reset method would have to know how deep to the initialization (which it won't know for a request scoped form that can be nested to N levels.) Typically I'd take the approach shown about half way down here: http://wiki.apache.org/struts/StrutsCatalogLazyList where I'd decorate using ListUtils in my reset method, but that only works when you know how deep you need to initialize things. Maybe I'll just try out a DynaActionForm.. still using a DynaBean inside of a regular ActionForm I'd think should work (assuming you populate all your nested items with LazyDyna beans. At least I think it should. I'll have to mess around more with it. I just want to be able to populate a nested set of maps to any level that will work with request scope. At this point, I don't even care about using standard pojos in my maps so dynabeans will be fine if it makes things easier.
Re: zoning out on some basic LazyDynaMap usage for a text field property?
Hmm,
I've never tried using lazy inside a standard ActionForm, the ones that I
have work inside of
a DynaValidatorActionFom (say that 3 times fast). Don't feel like writing a
reset method? you are
getting old Rick.

zoning out on some basic LazyDynaMap usage for a text field property?
I swore I used to be able to do this stuff... maybe it's Friday thing, but regardless I'm blanking on out on what I'm doing wrong with this... I have an ActionForm that has one property right now: private LazyDynaBean dynaBean = new LazyDynaMap(); My goal is to be able to populate this DynaBean with any level of nested DynaMaps and have everything populate correctly using Request scope on my form. (Not shown here but an 'answer' as a map value can end up being another Map and so on - nested to any level.) I'm currently having trouble defining the property name correctly. Here is a summary Not working: Error: Invalid argument looking up property: "dynaBean.map(question_1).map(answerString)" of bean: "myForm" Working fine:
