Please help!

Task accomplished

thanks

[gidion]

how about making this post worthwhile and posting how you accomplished this task

[nikhil]

hi,
How about displaying a bit more courtesy while posting a query?


Anyway,

Visit w3schools online tutorials on XML schemas (XSDs)

http://java.sun.com/webservices/docs/1.5/tutorial/doc/XWS-Security-schema2.html

Also, some information on alfresco wiki

In the web-client-config-wcm.xml, you can find the different types of select controls we provide in web forms:

           <widget xforms-type="xf:select1"
                   xml-schema-type="boolean"
                   javascript-class-name="alfresco.xforms.Checkbox"/>
           <widget xforms-type="xf:select1"
                   appearance="full"
                   javascript-class-name="alfresco.xforms.RadioSelect1"/>
           <widget xforms-type="xf:select1"
                 javascript-class-name="alfresco.xforms.ComboboxSelect1"/>
           <widget xforms-type="xf:select"
                   appearance="full"
                   javascript-class-name="alfresco.xforms.CheckboxSelect"/>
           <widget xforms-type="xf:select"
                   javascript-class-name="alfresco.xforms.ListSelect"/>

‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

We have two XForms controls, one for getting an individual selection from a user, and a second for getting multiple selections from a user.  For the single selection, we can present as a single checkbox if it is a boolean type in your XSD (and have that either selected or not selected by default), or we can present as a combox box (the default) or set of radio buttons (if you add the optional appearance annotation "full").

For multi-item selects, this can be presented as a list or checkboxes.  By default, if you've a limited number of items (5), it will present as a checkbox, whether or not you set an explicit appearance annotation.  If more than 5 items, it will present as a list.  If you have a large number of items and want to force checkboxes (override the default behavior to economize screen real estate and move to a list), you can use the appearance 'Full' annotation in your XSD.

An example XSD that shows the varying ways of list items can be displayed with different defaut values and uses of these controls based on appearances attributes follows here:

[nikhil]

thanks a ton Kevin!!!

[suniil]

Thanks kevin really useful.

I'd like to populate the list item from an XML file. can you please let me know where should i place the the XML file that need to be read by corresponding schema?

Many thanks in Advance.

To generate this list dynamically from an XML, you'll need to leverage an in-line JSP callout.  That JSP should be locating in your Web Project (in Staging) so that it can be executed via the Virt Server (i.e., you'll need to have that enabled).

That JSP will need to read from the file-system (if you've CIFS mounted) or use AVMRemote (the RMI interface to an AVM repository).  You can find examples of this in our training material, in our PR example (list of Company Footers) or by checking out from SVN and accessing our unit-tests for callouts in the web-client directory.

Kevin

PS … These lists really should be dynamically generated from an XML, so that business users can readily modify lists of selectable items.  That was the driver for in-line JSP callouts.  Remember, your JSP needs to return the simpleType to your XSD … once again, the examples should help here.

[suniil]

Back on project

Thanks kevin, that worked! But if we try to load the XML as you mentioned #, the interface display the content in listbox and able to select multiple choices. But FireFox browser refuses to generate the XML & HTML and throwing an error "Please provide a vaid value for xxxxxxxx". Same works perfectly with IE browsers.

#

<xs:include schemaLocation="/views/components/channel-list.jsp"/>

Alfresco version I use: 2.1 community

Any thoughts?

Hey there.
I have 2.2.0E and I dropped that xsd in exactly as is and it didn't work.

Here is the error I got in the UI:

Step Two - Author Web Content
Enter your document content into the repository.
org.alfresco.web.forms.FormProcessor$ProcessingException: org.alfresco.web.forms.xforms.FormBuilderException: error parsing schema: at line 19 column 42: src-resolve.4.1: Error resolving component 'four_presidents'.

If 'four_presidents' is intended to have a namespace, perhaps a prefix needs to be provided. If it is intended that 'four_presidents' has no namespace, then an 'import' without a "namespace" attribute should be added to 'null'.

And here is what is in the log file:
