But I'm stuck on struts 1.1 at my workplace and based on this http://www.niallp.pwp.blueyonder.co.uk/lazyactionform.html LazyActionform has been added to struts 1.2.6 Is it possible to plug this thing into 1.1?has anybody done that? Thanks I haven't heard of anyone doing it, but you should be able to. LazyDynaBean was added to Commons BeanUtils 1.7.0 and Struts 1.1 depends on a version prior to that. If you can upgrade to BeanUtils 1.7.0 then you have most of the functionality. You could use them as a property in your ActionForm - or replicate the Struts LazyValidatorForm (theres not too much to it), If you can't upgrade to BeanUtils 1.7.0 then you could just grab the source code for the two "lazy" classes you need (LazyDynaBean and LazyDynaClass) and they should work OK with BeanUtils 1.6.1 - which is the version that Ships with Struts 1.1 You can grab the source download from here for Commons BeanUtils: http://jakarta.apache.org/site/downloads/downloads_commons-beanutils.cgi Niall Niall > > > -- > > Puneet - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Re: DynaActionForm indexed properties
If you are using basic arrays you need to create an array for the item before the JSP is displayed. You might want to use a java.util.List instead, you don't need to pre-allocate when using Dyna forms.

DynaActionForm indexed properties
Hi, This is the first time I am trying to use indexed properties with DynaActionForm. Now the number of fields that I will have is not certain. So does that mean I cant use DynaActionForm. And i don't have normal strings in my list. I have a custom object. so what i have currently is something like this I cant specify any size because I don't know the size before hand. So this has no problems loading the page, but on submit it throws an ArrayIndexOutOfBoundsException. -- Puneet
