jpath problem

[Jo...@gmx.de]

Hi,

first let me say, that I really love the flow framework. Finally it 
can be fun to write web applications.

My problem is that I can't figure out how to pass objects other than simple
strings via the bizData object to the view layer.

In the example below I only get the users object converted to a string.
neither the getGroup() nor the getNames() methods get called.

What am I doing wrong?

Thanks,
Johannes Hofmann


in my flowscript I have:


var users = new Packages.test.Users();

sendPageAndWait("user.xml", {"users":users});



the relevant part of user.xml looks like:

Users Object:
<xsp:expr>
	<jpath:value-of select="users"/>
</xsp:expr>
Group:
<xsp:expr>
	<jpath:value-of select="users/group"/>
</xsp:expr>
Names:
<jpath:for-each select="users/names">
       	<jpath:value-of select="."/>
</jpath:for-each>



The corresponding JavaBean is:

public class Users {
    String [] names = {"foo", "bar"};

    public String getGroup() {
        return "myGroup";
   }

    public String[] getNames() {
	return names;
    }
}


PS: I tried xml-cocoon2_20021230172148.tar.gz.

Nothing. It's a bug in the implementation of the flow machinery. Ovidiu 
promised me that he will have looked after it a few weeks ago, but I 
haven't heard from him since then. I guess he's on vacation now.

Since I need this feature to work ASAP, I'm going to start debugging the 
problem in the coming days. If you want to follow my progress, you'd 
better subscribe to cocoon-dev.
