Service performFindList cannot work with Widget Forms for pagination?

[jonwimp]

Is anybody using service performFindList?

That service returns the actual list size (in context as "listSize"), and a possibly smaller list
(FastList). The problem is that when this list gets to the ModelForm.java (method
getListLimits()), the context value "listSize" is totally ignored, and the list size is gotten
from the partial list returned by performFindList. Obviously, this is wrong, since the actual list
size IS NOT the size of the partial list!

If I am allowed to fix the problem right here, in ModelForm.java, the following questions are moot.

I have another question, about service performFind.

In Minilang, how do I take the EntityIterator returned by that service, calculate some additional
values, and slap on those values into the list elements to be displayed in the UI listings output
as an additional column? For eg, I may have a simple logic like "if product name is profane,
display a big label VULGAR, else display a small label Mild". I'd want a product listing that has
the additional column called "Vulgarity alert".

OR...

Can I get the Widget Form renderer to look at 2 lists with the same sizes, and simply combine
them, like "row 1 of list A with row 1 of list B, and row 2 with row 2..."?

If I can somehow massage the EntityIterator from service performFind, I won't have to use
performFindList.

Or should I just go for freemarker macros in such cases?

Thanks.

If I'm not wrong, some time ago a new attribute has been added (to the
<form> element?) to specify a non default field (or value) containing
the actual list size... I think you should find it in the xsd file.

I think you can use the <row-actions> section in your form widget
definition; it is similar to the <actions> section but the actions in
the former are run for each and every row in the list.

Hi Jacopo,

It works, thanks!

It's attribute "override-list-size" for the <form> element. Just pump in the value of "listSize"
returned by the service "performFindList".

<row-actions> work. Very clean.
