Themfragments tile syntax

I am looking for the syntax for theme fragments tile (for mosaic).
I had this working once, so it should work (but I can not find the syntax)....

myfragment.xml

<model xmlns:form="http://namespaces.plone.org/supermodel/form" 
xmlns:i18n="http://xml.zope.org/namespaces/i18n" 
xmlns:lingua="http://namespaces.plone.org/supermodel/lingua" 
xmlns:marshal="http://namespaces.plone.org/supermodel/marshal" 
xmlns:security="http://namespaces.plone.org/supermodel/security"
xmlns:users="http://namespaces.plone.org/supermodel/users" 
xmlns="http://namespaces.plone.org/supermodel/schema">
<schema>
        <field type="zope.schema.TextLine" name="title">
            <title>Title</title>
        </field>
        <field type="zope.schema.TextLine" name="description">
            <title>Description</title>
        </field>
        
        <field type="zope.schema.TextLine" name="bla">
            <title>Bla</title>
        </field>
        <field type="zope.schema.URI" name="URL">
            <title>Title</title>
        </field>
  </schema>
  </model>

In the theme fragment.pt I tried all combination I could think of...., like

view/request/form/bla
context/request/from/bla
context/request/form/data/bla

etc..

Which versions are you using? The latest versions has normal view/data. Also, there's unmerged plone.app.tiles-branch, which supports fieldsets (will be merged, once I manage to write tests). (I'm currently using XML-configured fragment tiles daily - also with fieldsets.)

Thanks.
I use 2.0.4 (right now, I have checked out from github).

When I add the tile and enter the data, it shows up when I place it, but after I save, it gives an error.

Does it matter that I made it TTW ?

(do you have an example that works ?)


TTW should not matter.

There is not such version (2.0.4) of themefragments.

Would you have stacktrace for that tile rendering error?

I got location error for view/data/bla, ${view/data/bla} and view/bla (and tal define 'd=view/bla' tal:content='d/bla' />

I checked out the latest version from collective both of mosaic and theme fragments and now it works.
Thanks a lot..
