Re: Indexed Grid Representation on a Form

2001-05-17 Thread Jeff Trent 



I ended up getting it to work thru this hack 
below. I'd be curious if someone was able to do this dynamic grid entry 
gracefully using struts!!!


 % int i = 0; 
% logic:iterate id="customerContact" 
name="adminUpdateProfileForm" 
property="customerContacts" 
tr tdinput 
type='text' name="customerContact[%= i++ %].contactName" value="%= 
((com.mydomain.project.CustomerContact)customerContact).getContactName() 
%"/td 
/tr /logic:iterate

  No, this still generates an exception. If I 
  substitute i for 0 in your below example it works but that doesn't help me for 
  the iteration. Thanks, jeff.

  I think this should work (but obviously it 
  doesn't). Can anyone tell me why?
  
   % int i = 0; 
  % logic:iterate id="list" 
  name="adminUpdateProfileForm" 
  property="customerContacts" 
  tr 
  tdhtml:text 
  property="customerContact[%=i++%].contactName"//td 
  /tr /logic:iterate
  
  Where getCustomerContacts() returns a vector 
  of CustomerContact objects 
   getCustomerConact(int 
  offset) returns an CustomerContact element from that vector.
  
  thanks,
  jeff

What really is needed is a new html tag called grid or something that
handles this more gracefully.  Using the iterate tag seems to be a waste
since I'm not really using it for anything other than a counter placeholder.
I know its a departure from standard HTML form types but who the hell cares.
This would be really useful addition instead of mixing html tags in with
iterate tag to accomplish something that should be simple.  Maybe I'll write
a taglib for this...

So reading your comments, Jim, it sounds like your using code analagous to
this but your implementation uses a map instead (?)

BTW, now that I'm using html field names like customerContactName[0].title,
I find that conventional javascript to set focus doesn't work - I get
javascript errors.  Any ideas how to reference these fields?

thanks,
jeff

 It should be:

  % int i = 0; %
  logic:iterate id=list name=adminUpdateProfileForm
property=customerContacts
 tr % i++ ; %
  tdhtml:text property=%= \customerContact[\ + i
\].contactName\ %//td
 /tr
  /logic:iterate

 You need to replace the whole string. The exception would have been from
 the BeanUtils not able to understand what the [i] would have meant. If you
 have an iterator in a scriptlet, then you need to always use a scriptlet
 to access it. Usually. Mostly.

 I had a feeling there was a change made to iterate recently to give you
 an index value, but I can't remember what it was.

 I usually use a Map and have the key as the integer value in the index
 for the entry. Works well when you don't have liner numbering in the
 list of key/value pairs.
