Branch Failure

Question

Hi,<BR><BR>
Can anyone help with this? It's driving me nuts.<BR><BR>
I have a page with two regions on it.<BR><BR>
The first region is a simple wizard built form.<BR><BR>
The second region is a PL/SQL region to create items based on the records in a lookup table using the following code:<BR><BR>
DECLARE<BR>
--Cursor to pull out all active records from RES_DLV_CONSERVATION table<BR> cursor c_records is <BR>
select CON_ID, CON_SCHEME <BR>
from RES_DLV_CONSERVATION <BR>
where CON_ACTIVE = 1;<BR><BR>
--Variables to hold the records from the cursor<BR>
v_id number;<BR>
v_record varchar2(4000);<BR><BR>
BEGIN<BR><BR>
--Open a table to hold the manually created Accreditation form<BR>
htp.p('<table>');<BR><BR>
--open cursor and loop through records populating variables<BR>
open c_records;<BR>
loop<BR>
fetch c_records into v_id, v_record;<BR>
exit when c_records%notfound;<BR><BR>
--Build a form dynamically using the variables.<BR>
--Use the record id to create the names of the form items <BR>
--so they can be referenced later. <BR>
--('chk_' prefix for checkboxes, 'inp_' prefix for text)<BR><BR>
htp.p('<tr><BR>
<td width="50"><BR><font class="label_def">'||v_record||' </font></td><BR>
<td width="50"><BR>
<input type="checkbox" name="chk_'||v_id||'" id="chk_'||v_id||'" /></td><BR>
<td width="160"><BR>
<font class="label_def">Names of Accredited Staff</font></td><BR>
<td><BR>
<input type="text" name="inp_'||v_id||'" id="inp_'||v_id||'" style="width:300" /><BR>
Seperate each name with a comma (,)</td></tr><BR>
');<BR><BR>
end loop;<BR>
close c_records;<BR><BR>
--Close table<BR>
htp.p('</table>');<BR><BR>
END;<BR><BR>
There are currently no processes on the page.
I have a branch on the page with a single button that uses the branch.<BR><BR>
The problem is that when I click on my button the branch fails and I get a page cannot be displayed error.<BR><BR>
The only way I can get the branch to fire is by conditioning out the PL/SQL region. So there must be something in there interfering with the branch.<BR><BR>
I've tried putting the button everywhere on the page and reordering the sequences on the region to no effect.<BR><BR>
Any ideas???!???<BR><BR>
Cheers<BR>

Thanks BarryG,
I've gone through this process several times already. Believe me...
I've managed to solve it .. sort of....
The code is fine. I'm pretty sure of that now. After wading through the source code for that renered page I discovered that if I prefix my items with:
'p_t[value greater than the last wizard generated form item]'.
i.e. using the same convention as Apex uses, then the branch fires ok.
This sort of solves my problem for now but I'll try building a process from it and see if I can reference the items to populate my tables.
As far as I can work out the issue seems to be with some kind of internal validation that is going on with form items in Apex.
Without seeing the source (which I probably never will) I can't tell what, but there is some PL/SQL somewhere that fails when it finds a form item without the p_t prefix I recon.
Can any of the development guys shed any light on this??
Cheers
