Nillable

General Questions/Discussions
1

Hi Jick,

Sorry to be a pain but blame M$…their dot net framework code is complaining that it wants to see the nillable attribute otherwise it goes nuts…something to do with how it serializes the objects…

I have hacked the code for xsdElementAttribute to be as follows as a work around. Can you ask your engineers to let me know if there is a more elegant solution?

$attribute.t_prepare($args.get(“property”))##

===== Output =====

#if( $attribute.isComposite() )
$stacks.getStack(“composite”).push($class)##
#set($class = $attribute.getType())
$stacks.getStack(“referenceAttribute”).push($referenceAttribute)##
#set($referenceAttribute = $attribute)
#parse("$template-dir/XsdClassSelection.vm")
#set($referenceAttribute = $stacks.getStack(“referenceAttribute”).pop())##
#set($class = $stacks.getStack(“composite”).pop())##
#else
$indenter.getIndentation()<xs:element ##
#if( $attribute.getType().isElement() )
ref##
#else
name="$attribute.getName()" type##
#end
="$attribute.t_getTypePrefix()$attribute.t_getTypePrefixPostfix()$attribute.t_getTypeName()" minOccurs="$attribute.t_getMinOccurs()" maxOccurs="$attribute.t_getMaxOccurs()"##
#if( $attribute.hasDefaultValue() )
${space}default="$attribute.getDefaultValue()"
#end
#if ($attribute.getType().isElement() !=true)
#if ($attribute.t_getMinOccurs()==“0”)
$space nillable=“true”##
#else
$space nillable=“false”##
#end
#end
>##
$indenter.push($indentation)##
$attribute.t_getDocumentation($indenter.getIndentation())
$indenter.pop()##
$indenter.getIndentation()</xs:element>
#end

Hi Toby,

Please try this:

#if ($attribute.getType().isElement() !=true)
   #if ($attribute.t_getMinOccurs()=="0")
       ${space}nillable="true"##
   #else
       ${space}nillable="false"##
   #end
#end

Best regards,
Jick

Thats what I wrote! :slight_smile:

Oh, I didn’t aware that. I am sorry that this is already the most elegant way. :frowning: :frowning:

Cool - I am finally elegant!

Hi Toby,

Our engineers just spot a different:

Yours : $space nillable=“true”##
Ours : ${space}nillable=“true”##

Your approach will produce two spaces. Not a show stopper though :smiley: :smiley:

Best regards,

Thats why they are engineers and I am a user…

Any chance of an updated document set with all the calls and functions in? I cheat and look at some of the other InstantGenerator code samples and lift bits and bobs…even if it is an unsupported document set it would be handy.

As I mentioned, I am off to a new project so I am not sure what the requirements will be but anything that you have which is useful is handy…

Cheers Jick, have a good weekend

Hi Toby,

I have just requested for a more updated version of the API spec. Please find it attached.

Hope you find it useful.

Enjoy your weekend!

Hi Jick, to save me from downloading Open Office can you export it as a HTML or PDF?

Hi Toby,

Certainly. Please find the HTML version attached (zipped).
