Re: handling XML Node deletion in CForms

[Jeremy Quinn]

Now, I realise that the Shot Previews cannot be deleted by JavaScripts in the Binding, because the user may decide to cancel the form operation after they have removed Shots in the repeater rows.

So I need to maintain a record somehow of what Shots are being deleted, so I can then remove the Shot Previews only after the form is submitted.

Hrumph !

Is there some way to have a FlowScript function called from the binding when node deletion takes place in a CForms repeater ?

You could try using a <fb:javascript> element inside the <fb:on-delete-row> element of your repeater binding. I haven't tried it myself, so I'm not sure if it'll work, but you never know...

Thanks for your reply.
Something I stupidly forgot to mention, I am using a simple-repeater, it does not take fb:on-delete-row.

Simple repeater does not make a diff IIRC. It just removes *all* rows and readds the new ones. So an event on-delete-row does not make sense for it.

TBH. I am a bit confused about the two repeaters and how they work with an XML Model.
This is what I have (this project still uses 2.1.4 and Woody) :

<wb:context
xmlns:wb="http://apache.org/cocoon/woody/binding/1.0";
xmlns:wd="http://apache.org/cocoon/woody/definition/1.0";
path="/storyboard">
<wb:value id="title" path="title"/>
<wb:value id="description" path="description"/>
<wb:value id="creator" path="creator"/>
<wb:value id="count" path="string(count(shots/shot))" direction="load"/>
<wb:simple-repeater id="shots"
parent-path="shots"
row-path="shot">
<wb:value id="id" path="./@id"/>
<wb:value id="title" path="title"/>
<wb:value id="description" path="description"/>
<wb:value id="wasshot" path="wasshot"/>
<wb:value id="shotok" path="shotok"/>
<wb:value id="created" path="created"/>
<wb:value id="preview" path="preview"/>
<wb:value id="mimetype" path="preview/@mimetype"/>
</wb:simple-repeater>
</wb:context>

to edit this :

<storyboard id="blah">
  . . .
  <shots>
    <shot id="blag">
        <preview ref="0123456789" mime-type="image/jpeg"/>
      . . .
    </shot>
    . . .
  </shots>
</storyboard>

Can I use (non-simple) Repeater with this?
Plus have Up, Down, Delete and Add buttons.

Thanks

regards Jeremy
