Dave, good to know we think alike. We are in the same page.

I need to:
1) Figure out the name of the select form element

The name of the form element is mounted in this line
set element "${prefix}$role(short_name)"
the output is: role_resolver

API workflow::role::get_assignee_widget
file wrokflow/tcl/role_procs.tcl line 740

2) Find out where the matching variable is set.
This is exactly what i was trying to do all the time i am debuging the APIs listed before
There's no matching of variables, or at least i haven't found it yet


Two main procs build the ad_form element
1. workflow::role::add_assignee_widgets
2. workflow::role::get_assignee_widget


1. It has the line
ad_form -extend -name $form_name -form [list [get_assignee_widget -role_id $role_id -prefix $prefix -mode $mode]]


2. It has the line

return [list "${element}:search(search),optional" [list label $role(pretty_name)] [list mode $mode] [list search_query $query] [list options $picklist]]

If we combine the output of 1 and 2 we have

ad_form -extend -name $form_name -form {

{role_submitter:search(search),optional {
label #bug-tracker.Submitter#}
{mode display}
{search_query {select distinct acs_object__name(p.party_id) || ' (' || p.email || ')' as label, p.party_id
from cc_users p
where upper(coalesce(acs_object__name(p.party_id) || ' ', '') || p.email) like upper('%'||:value||'%')
order by label}}
{options {
{ "Unassigned" "" }
{{carl manager (mailto:iuri_sampaio@yahoo.com.br)} 1134}
{{iuri sampaio (mailto:iuri.sampaio@gmail.com)} 643}
{{jim dispatcher (mailto:iuri_sampaio@computer.org)} 1137}
{{john dispatcher (mailto:iuri.sampaio@computer.org)} 1795}
{ "Other..." ":search:"}}
}}
}
}

That's everything the APIs do. Where is the matching that sets the correct values to show up on display mode then?

At first i thought the var list $query would do the match but i confirmed it doesn't by removing it from the code and i didn't get errors.

But then I see it is acs-templating that does the magic! The matching is in the API ad_proc -public template::widget::search

input type="hidden" name="role_resolver:select" value="t" select name="role_resolver" id="role_resolver"
option value="" Unassigned /option
option value="1127" selected="selected" bob technician (mailto:iuri@dcc.ufba.br)</option>
option value=":search:" Other.../option
/select


option value="1127" selected="selected" bob technician (mailto:iuri@dcc.ufba.br) /option

Now i need to figure out how to get the selected user id

It's returned as a list using the workflow::case::role::get_assignees api. This is used by workflow::case::role::set_assignee_values and extracts the first element to set it during display mode.

Or, I was wrong and Deds knows exactly how it works....

Deds,

workflow::case::role::get_assignees
workflow::case::role::set_assignee_values

Both procs use case_id as parameter and i don't have it from advance. I have only workflow_id, role_id and bug_id

How would i get the user_id of the resolver in the display mode?
I want to get the user_id, to pass it as parameter of an API, to use it in another field of the ad_form.

something like:

workflow::role::add_assignee_widgets -workflow_id $workflow_id -form_name bug -roles resolver

which is the API that returns the the ad_form element of the resolver on display mode.

Then i want to use the resolver info, only user_id.

ad_form -extend -name bug -form {
{item:text(select),optional
{label "Equipment"}
{options {[bug_tracker::get_items -user_id $role_resolver(user_id) -bug_id $bug(bug_id) -workflow_id $workflow_id]}}
{mode display}
}

I created the API bug_tracker::get_items
Attention to parameter $role_resolver(user_id)
This is a guess! Precisely what I am trying to figure out.

How to access the data structure (ad_form element) that holds the resolver info, in order to use it?

Iuri,

You can get the case_id so that you can use it as parameter to workflow::case::role::get_assignees in addition to role_id.

Check the code in bug-tracker/www/bug.tcl then just use your values for bug_id

set case_id [workflow::case::get_id -object_id $bug(bug_id) -workflow_short_name [bug_tracker::bug::workflow_short_name]]

Deds and Dave,

Problem solved. I ended up creating an API
ad_proc bug_tracker::get_items

the main part of it is:

set role_id [workflow::role::get_id -short_name $role -workflow_id $workflow_id]

set user_id [lindex [lindex [workflow::case::role::get_assignees -case_id $case_id -role_id $role_id] 0] 3]

the rest, i followed your tips above in this thread to get the parameters here and there

Thanks a lot!
