Using import statements in the WCM web form XSD

[tamilraj2003]

In the web form creation, if my XSD has to refer or import many other schemas from public locations, how it could be accomplished? Though my XSD refers such schemas with public domain URLs, alfresco throws “org.alfresco.web.forms.FormProcessor$ProcessingException: org.alfresco.web.forms.xforms.FormBuilderException: error parsing schema: at line 91 column 41: src-resolve: Cannot resolve the name 'georss:where' to a(n) 'element declaration' component.â€

Are you able to post your XSD, or a small example that demonstrates the problem?

Here is the XSD I am trying to use.

I am using the Google Open Social schema, to generate a web form as my POC

When I try to create content for this web form (after creating the form, I did add to a web project), I get  this error

“org.alfresco.web.forms.FormProcessor$ProcessingException: org.alfresco.web.forms.xforms.FormBuilderException: error parsing schema: at line 91 column 41: src-resolve: Cannot resolve the name 'georss:where' to a(n) 'element declaration' component.â€

Are openSearch.xsd, gd.xsd, georss.xsd, gml.xsd and xml.xsd installed in the root directory of your Web Project, and have they been promoted to the staging sandbox?

As described at http://wiki.alfresco.com/wiki/Forms_Developer_Guide#Overview_of_supported_XML_Schema_structures_and_..., when you xs:include or xs:import an XML schema using a relative URL, that schema must be stored within the Web Project itself - only absolute URLs in schemaLocations are loaded from outside the Web Project.

Hi,

is it possible to import a xsd added in data dictionnary/web forms ?

Thanks in advance.

[pmonks]

Not currently, no.  Imports / includes must be located in the Web Project to which the Web Form is associated (which may mean that the import / include files need to be stored multiple times if the Web Forms that import / include them are associated to multiple Web Projects).

There's an enhancement request in JIRA that's intended to allow importing / including of a Web Script (which could be used to include an XSD from anywhere in the repository via the built-in /api/content Web Script).  The issue is https://issues.alfresco.com/jira/browse/ETWOTWO-77 - I'd encourage you to vote and/or comment on it if you feel that this functionality is important.

Cheers,
Peter
