facesContext is null while running a java-backed webscript

[walid]

Hello,

I'm writing an AMP for alfresco explorer 3.2r

webscript description file :

<webscript>
    <shortname>Créer des regles de contenu</shortname>
    <description>Créer des regles de contenu</description>
    <url>/xxxx/contentRules/trywebscript</url>
    <authentication>admin</authentication>
    <format default="">argument</format>
</webscript>‍‍‍‍‍‍‍

Java class for webscript :

public class RuleUtilScript extends AbstractWebScript {
public RuleUtilScript() {
     }
    @Override
    public void execute(WebScriptRequest req, WebScriptResponse res)
            throws IOException {
        CreateRuleTest ruleTest = new CreateRuleTest();
        ruleTest.createRule();
        res.getWriter().write("yup, i did it !!");
    }
}‍‍‍‍‍‍‍‍‍‍‍

In module-context.xml :

    <bean id="webscript.xxxx.contentRules.trywebscript.get"
        class="fr.xxxxxx.alfresco.xxxx.CreateDynamicContentRules.RuleUtilScript"
        parent="webscript">
    </bean>‍‍‍‍

I followed http://wiki.alfresco.com/wiki/Java-backed_Web_Scripts_Samples, i found the webscript registred in /service/index, when i run it, it throws :

16:21:24,651  ERROR [web.scripts.AbstractRuntime] Exception from executeScript - redirecting to status template error: null

In debug :
this line : UIContextService.getInstance(FacesContext.getCurrentInstance()).notifyBeans();     throws NullPointerException
====> FacesContext.getCurrentInstance() returns null.

I spent some hours on this, i tried to add managed-bean to faces-config-custom.xml but with no success.

thanks in advance

I understand that it's normal, java backed webscript is running from a 3rd party tool so it's out of JSF lifecycle.
Actually i did my best to run away from FacesContext but as i need conditionHandlers and actionHandlers i can't get away, now i'll do it with simple script and running it from alfresco should not fire this exception.

if someone know how to do it in webscript please tell me

Thanks,
Walid
