Hello all,
I'm having an issue with BeanForm (version 0.9). I have a feeling it's
something I'm missing - but I've done about all the research and probing I can
think of to no avail.
The particulars - I'm executing in Jetty 4.2.27 (old, I know - but it seems
rather trusty) on ubuntu linux. My tapestry jars are the 4.1.5 release, I'm
using tacos 4.1.1. Along with OGNL 2.7.2 (hope I didn't forget anything).
I've searched the exceptions and errors messages, I've went through the source
code for the component, and I've done a bunch of searches in MarkMail and
Nabble. I found a promising lead, but that too doesn't work.
So - I have pojo, Band, and I am able to use BeanForm to create a new pojo (and
persist, etc).
[my .html]
------------------------------
<form jwcid="[EMAIL PROTECTED]:BeanForm"
bean="ognl:bandPojo"
exclude="bandId"
delegate="bean:validationDelegate"
clientValidationEnabled="ognl:true"
focus="ognl:true"
method="post"
save="listener:save"
delete="listener:delete"/>
But when I enter my edit page from the view-all page with a pojo specified for
editing, I get the following 4 exceptions (which result one from the other, I
think):
--------------------------------------

Now - I found a message from Sept 2006 that mentioned there is an issue with
BeanForm being used in a Form tag. I believe it's a modification from 4.0 to
4.1 regarding the Form component:
http://www.nabble.com/I%27m-trying-to-get-the-marvelous-BeanForm-component-working-with-tap-4.1-td6119786.html#a6122605
I thought "DANG! THAT'S GOTTA BE IT!" Because my problem appears to be related
to the Form component being rewound. So I changed .html
[my .html]
------------------------------
<form jwcid="@Form">
<span jwcid="[EMAIL PROTECTED]:BeanForm"
bean="ognl:bandPojo"
exclude="bandId"
delegate="bean:validationDelegate"
clientValidationEnabled="ognl:true"
focus="ognl:true"
method="post"
save="listener:save"
delete="listener:delete"/>
</form>
I still got that above exception. I mucked with the delegate, client
validation, and still get the exception.
Sorry for the excessive length - it's just that I've done a bunch of research,
debugging, and looking into this... so I wanted to make sure I included all the
details.
Thanks,
Andy
