widget logic help

I am working with the requirement screens.
On a screen it calls a form.
The form is a list, before it calls the form it puts a hyperlink to add a new role.
I am working on ListRequirementRoles.
I want to change the behavior so if there is a role it does not have the add role, and if the list is empty it displays the hyperlink.
This is pretty easy in ftl. I spent all day tryong to get a working method using the requirementscreens.xml
When I check for the list
                <entity-one entity-name="Requirement" value-field="requirement" auto-field-map="true"/>
                <entity-and entity-name="RequirementRole" list="requirementRoles">
                    <field-map from-field="requirementId" field-name="requirementId"/>
                </entity-and>
using
                                    <condition><not><if-empty field="requirementRoles"/></not></condition>
I can display the widget or the failed widget, but the failed widget does not seem to have any of the values set in my actions.
I could do it on my form (added a second form called new role), but if it did not use a list type I could not seem to see the list, if I made it a list, but there were no records I could seem to get the hyperlink to show up.

Just thought I would ask if any of you experienced folks have the syntax to get one row out of the roles entity so I can have a non list form and check a value to say display hyperlink?

I am going to do it in FTL for now, as I know the syntax, but thought I would ask for next time.
Maybe I completely do not understand compare in general, or use when on the forms. I would of thought I could just do some compare to say if I am going to show the hyperlink on the screen and would not of needed an additional form etc.

Try this :

<entity-one entity-name="Requirement" value-field="requirement"/>
<entity-and entity-name="RequirementRole" list="requirementRoles">
    <field-map from-field="requirement.requirementId" field-name="requirementId"/>
</entity-and>

...

<condition>
   <not><if-empty field="requirementRoles"/></not>
</condition>


Or

<entity-one entity-name="Requirement" value-field="requirement"/>

<get-related relation-name="RequirementRole" list="requirementRoles" value-field="requirement"/>
...
<condition>
   <not><if-empty field="requirementRoles"/></not>
</condition>

Thank you for the help.
I completed this using ftl where I could just check if the list had content.
I later modified as I realized users may wish to keep history (more then one supplier).
I changed the logic in the ftl to verify that there were no suppliers with no closing and that the closing if there was prior to now. In this way it keeps them from having two current suppliers.
If you have two current suppliers it will create P.O. for both with the same order quantity (not half or anything, so would duplicate the order). I verified if one was off by close date it did not create a P.O. for them. This way they can have historic suppliers etc, but still only have one active.
I also modified the drop down for selecting supplier to only display suppliers (was showing all parties).

I believe I had it sort of working using xml, but when I added the if clause it appeared to cancel the whole widget. The failed widget did not seem to have the entities and such.
I really just wanted it to not do the hyperlink part of the page but do the include with data from actions.
Worked out ok in FTL, I had to add more logic anyhow.

I need your source code to help you, just with a description it really
hot :)

Sorry,
I thought I mentioned the screen name.
I was just trying to not show the add link if the list had content.

I ended up using a ftl where I check to see if there is no content or if there is if the through date is before today, so it will not have two suppliers for the same time period.

I could of sworn it did that for assigning suppliers before, where adding a new on automatically added the through date, but does not seem to do that now.
