Null Pointer Error with this Form XSD

grumpy_burton — Mon, 26 Feb 2007 03:45:36 GMT

Any ideas why this would cause a Null Pointer Exception when using the "Create Web Content Wizard" on "Step Two - Author Web Content" ?<?xml version="1.0" encoding="UTF-8"?><xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:complexType name="process-unit"> <xs

i'm guessing it's because this schema doesn't define any elements - only types. i'll verify now - and add in a better error message if that's the case - but my hunch is that you need a minimum of one element defined in the schema.

i've filed http://issues.alfresco.com/browse/WCM-356 to track this issue.

So following your suggestion I've added an element

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="process-unit">
        <xs:complexType >
            <xs:sequence>
                <xs:element name="name" type="xs:normalizedString"/>
                <xs:element name="introduction" type="xs:string" minOccurs="1" maxOccurs="1"/>
                <xs:element type="xs:anyURI" name="workflow-diagram"/>
                <xs:element name="goal" type="xs:string" minOccurs="1" maxOccurs="1"/>
                <xs:element name="objectives" type="xs:string" minOccurs="1" maxOccurs="1"/>
                <xs:element name="approach" type="xs:string" minOccurs="1" maxOccurs="1"/>
                <xs:element name="supporting-process-units" type="xs:normalizedString" minOccurs="0" maxOccurs="unbounded"/>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

But now I get the following error:

Step Two - Author Web Content
Enter your document content into the repository.
XMLHttpTransport.watchInFlight Error: Error: bind has no properties
To continue click Next.‍‍‍‍

Any ideas?

Cheers,
Alex.

ok, worked fine on my mac at home with firefox 2.0.0.1

um.. also doesn't seem to work with IE 6.0.2900

well… that leaves me with no options at work now…

It shouldn't make any difference that this is a remote server should it? I'm basically running alfresco on port 8080 and have my firewall doing a port forward from outside on port 80

it definitely should be working with a remote server. it should also be working with ie 6.0. i'll investigate and get back to you.

Hi,

I have created a Jira issue for a problem I have found with port forwarding:
http://issues.alfresco.com/browse/WCM-364

Could this be linked to your problem?

However, I took your XSD from above to create a Web Form with, and was successful in using it to create content within a Web Project when I specified the port on the connection URL.

i.e.
Port 90 forwarded to 8080 on my local machine
I had issue with:
IE set to use port 90 for connection
Connected to alfresco using http://mymachine/alfresco

I had no issue with:
IE set to default connection
Connected to alfresco using http://mymachine:90/alfresco

Thanks,

Steve
