Managing 'error in services' in screen

[g.fitini]

Hi, i'm using apache ofbiz 12.04.01, i want to know how to manage error (how
to ingore errors of execution) in services that are executed in the screens.

For services in the *form exist an attribute like : ignore-error="true"

 

While for services called inside a screen it doen't exist

 

 

<!-- Screen -->

                <screen name="findScreen">

                               <section>

                                               <actions>

                                                               <set
field="titleProperty" value="PageTitleFindParty" />

                                                               <set
field="headerItem" value="find" />

                                                               <set
field="tabButtonItem" value="findparty" />

 

                                                               <service
service-name="findParty" auto-field-map="parameters" />

                                               

                                                               <!-- chiamata
al servizio -->

                                                               <service
service-name="XXXXXX">

 

</actions>

                                               <widgets>

 
<decorator-screen name="main-decorator"

....

...

 

I want to ignore each error who could be happen in service "XXXXXX".
How i can do that?!?.

Thanks in advance
