RE: DynaActionForm and JSTL (was RE: DynaActionForm Advantages)

[Jennings, Christofer J.]

My mistake. I was thinking DynaActionForm is a Map.

It'd be a shame to not be able to use JSTL and DynaActionForm together (I
think). As a general question, How much work would it be to have a
MappedDynaActionForm subclassing DynaActionForm as an optional base class
for our forms?

This would only work if ${form} implemented the Map interface.

Making the DynaBean interface extend the Map interface seems like a 
lot of overkill considering the number of places people might want to 
use it that have nothing to do with the JSTL...

Maybe you could make a case for having DynaActionForm implement Map, 
with a bunch of unsupported operations and delegating to the values 
hash otherwise.  It's still kind of cluttered, but at least it's off 
in Struts serving a specific need, instead of in beanutils.

DynaActionForm and JSTL (was RE: DynaActionForm Advantages)

[Jennings, Christofer J.]

Looking at the JSTL 1.0 specification, section 3.3, leads me to believe that
DynaActionForm "properties" can be accessed through the JSTL EL but with a
different syntax than a regular JavaBean property.

Example:
Regular JavaBean (e.g., ActionForm) EL syntax:


Map (e.g., DynaActionForm) EL syntax:



If anyone has done this sort of thing I'd sure like to know how it works.
Especially how/if accessing "aSubProperty".

I'm stuck using a container that can't support JSTL and I'm also not using
Struts 1.1 yet either so I can't confirm any of this.

Number formatters for form fields?

[Jennings, Christofer J.]

Is there a way to assign a number formatter to a field? I have an int field
the should display as 4 digits with leading zeros, like 0020 instead of 20. 

It would be nice to use a formatter instead of String conversions (I think).

Change the line in ApplicationResources.properties to instead read:

   note.range=We only go between {0} and {1}.

That is, you should have braces ('{' and '}') around the ints instead of
parens.

RE: No getter error

I believe these issues are centered around the switch to using the Jakarta
Commons bean utilities that occured (I believe) with the Struts 1.1b.

The code is in the package org.apache.commons.beanutils - the javadoc is
on-line in the Jakarte Commons area.

Craig pulled a bunch of the bean population stuff out, made it more
generic, added a bunch of automatic type-conversions, etc. Then he put it
over in the Commons area so it can be used by a bunch of other Jakarta
subprojects.

The docs on all this are still a bit lean - but the code is solid. It makes
it simpler to have form bean properties of all different types.

Yep, that may be the approach I take although it circumvents the front
controller. Not necessarily a bad thing. It just disperses business logic,
configuratin, and, in event that the assertion fails, navigation logic. It
would be nice to have this all reside within the front controller and
configurable via one source (the struts-config file).

Form action based on bean presence

[Jennings, Christofer J.]

I'd like to set a form's action based on the presence of an bean. The code
below fails during compile at the first  tag, saying that it
is a mismatch.

 start snip ---







...


 stop snip 

My gut feeling is that I would have to nest the whole form block in each
logic block to make this work. ... Right or wrong?

I really don't want to nest the form like that because it would make too
much code duplication. For the time being I've set the form to default to
one option then switch it if needed in a JavaScript function. That works but
seems ugly. Is there a better option?

RE: How to compare a notNull string with the nullString!

I came across this yesterday. Here's what I found. If a bean exists with a
null field, doing a logic:present on the field return true and comparing it
(e.g., using logic:equals) gets a NullPointerException.

If there is a custom tag to check for null values I'd love to know it.

Best practice for using constants

Hi,

I want to fill radio button values with values from a constants class. What
