Re: [CVS] - Flow broken?

[Christopher Oliver]

I looked into this but I don't quite understand why it's occurring. The 
change I made to sendPage() makes it behave uniformly with 
processPipelineTo(), so it seems like this was an existing problem (i.e. 
it would have occurred anyway with processPipelineTo()). Can someone 
explain what's going on here?

I've been experiencing a similar error with the slide samples after
updating CVS recently. There the error occurs when doing a sendpage in a
nested flow call:
The execution trace looks like:

request:
     --> map:call
                --> sendPage()
                           --> map:call
                                      --> sendPage()
The stacktrace I am getting:

You're right. CallFunctionNode needed modification. Originally, I 
forgot to check in that change. What do you mean by "it 
     

does not work 
   

with the authentication-fw"?.
     

It is related to the authentication-fw flow. The sitemap goes 
to this internal pipeline that is a flow function:

<map:match pattern="do-login">
 <!-- try to begin a session -->
 <map:call function="login">
   <map:parameter name="handler" value="authhandler"/>
   <map:parameter name="parameter_name" 
value="{request-param:username}"/>
   <map:parameter name="parameter_password"
                                          
value="{request-param:passwd}"/>
   <map:parameter name="protected-redirect"
                                        
value="{request-param:resource}"/>
   <map:parameter name="failure-redirect"
                       
value="entrada?resource={request-param:resource}"/>
 </map:call>
</map:match>

The flow function is:

function login() {
 var handler = cocoon.parameters["handler"];
 if (auth_isAuthenticated(handler))
     auth_success();
 else if (auth_login(handler, null, cocoon.parameters))
   auth_success();
 else
   auth_failure();
}
The problem looks to be related to this line (cca. 187):

doc = SourceUtil.toDOM(source);

in the PipelineAuthenticator.java

The error is:
