Compound/C-struct property

hbf — Thu, 23 Aug 2007 12:31:45 GMT

Hi,I need an aspect that maintains a set of email addresses and for each of these I want to save the datetime when the email address was last verified to work. So I need a list of a (C-like) struct that holds a single email address and a single date. How can I do this?<aspect name="bla:contactabl

Hi,

IÃ‚Â´ve got the same problem as you explain, and I donÃ‚Â´t know the solution for this issue.

Please, if someone has any idea give it us.

Thanks in advance!

The way I see it, Alfresco can model this: Using child-associations you can "embed" (composition) into your type a variable-length array of instances of another type.

So in principle, the problem is solved. However, I see two issues with the current Alfresco Web Client that make the above approach very, very difficult for the end user:

14:55:37,905 User:admin ERROR [node.integrity.IntegrityChecker] Found 1 integrity violations:
The association child multiplicity has been violated:
   Source Node: workspace://SpacesStore/f7d07486-5a1c-11dc-8a59-19e8c96a8993
   Association: Association[ class=ClassDef[name={http://www.baselgovernance.org/icar/model/knowledge_center/content/1.0}content], name={[blabla]/model/knowledge_center/content/1.0}test-child-association, target class={[blabla]/model/knowledge_center/content/1.0}smallet, source role=null, target role=null]
   Required child Multiplicity: 1..1
   Actual child Multiplicity: 0
14:55:38,051 User:admin ERROR [ui.common.Utils] A system error happened during the operation: Unknown Exception in Transaction.‍‍‍‍‍‍‍

2. More importantly, the current Alfresco Web Client only supports types that inherit from cm:content but in an composition we do not always want cm:content's properties.I think we need help/clarification here by an Alfresco engineer. Could somebody comment on this?

Hi

We have a design session planned for Friday on the topic of composite objects - both service implications (e.g. check-in) and UI.

Definitely something we will resolve - possibly with some help from a collabroative dev effort with a partner/customer.

Cheers
Paul.

Hi Paul, any update you can share here?

I am very much interested in this as well! So you have at least two good listeners 😉

What came out was that the steps to resolve ideal behaviour are actually in the copy and checkout services:

Comments welcome.

On Checkout is the onCopy fired in addition to the onCheckout?

Also, what does it mean to remote an aspect? remove?

FYI:

I've looked at the UI side of the problem in the meantime and tried - without success - to write a AMP that allows you to show a special version of the standard child-associations UI in which there is not a "Search" button but a "Create" button instead. Clicking the button would create a new instance of the association's target type and would add it as a child to the given child-association.

You would show this special version by setting the "component-generator" attribute in web-client-custom.xml, for instance:


   <config evaluator="aspect-name" condition="my:person">
      <property-sheet>
         <show-child-association name="my:postaladdresses"
            component-generator="ChildAssociationCompositionGenerator"
            display-label="Postal addresses"/>
            …
‍‍‍‍‍‍‍‍

To implement this, I subclassed UIChildAssociationEditor to UIChildAssociationCompositionEditor and tried to change BaseAssociationEditor's default implementation of encodeBegin() to show within the current property sheet other property sheets: one for each child in the child-association, and in addition, the aforementioned button "Create".

Unfortunately, this resulted in an error, and this is where I am stuck.


00:05:18,327 User:admin ERROR [renderkit.html.HtmlGridRendererBase] Wrong columns attribute for PanelGrid document-details:document-props:assoc_my_postaladdresses:_id0: 0
‍‍‍

If anybody is interested, I can provide more information. As I do not have this much time, I will hardcode the properties of my model for the time being…

I have found a temporary solution. See this forum post.
