Hi.
Please help me out to get started. I'm having hard times to find stuff
in the documentation
I'm building a new application. I correctly mapped the "ViewItem"
screen. Once I go on the ViewItem url I want to
1) Take the "artnr" request parameter
2) Execute the service "findItem" with the "artnr" as argument
3) Show a form filled with the data of the found item
I run 1 and 2 in the "actions" section of the "ViewItem" screen. I can
see that "item" is now put into the context.
Then I include the following form:
<form name="ViewItem" type="single"
title="Item information"
header-row-style="header-row" default-table-style="basic-table">
<field name="artnr">
<display-entity entity-name="Item" />
</field>
<field name="text">
<display-entity entity-name="Item" />
</field>
</form>
Which causes an exception "Passed primary key is not a valid primary
key: [GenericEntity:Item][text,(java.lang.String)])" as display-entity
tries to load an other instance of Item.
Ok, then maybe I should use
<field name="artnr"><display/></field>
<field name="text"><display/></field>
but this does not show any value for "text", altough it is not null,
neither does
<field name="Artnr"><display description="${item.artnr}"/></field>
work since item is of type generic value (?).
Could you please tell me if i'm using the wrong approach??
