Hidden SimpleTreeDropdownField in 2.4 / r395

7 May 2010 at 1:05am
I'm having difficulty with the SimpleTreeDropdownField in Silverstripe 2.4 Final and release 395 of DataObjectManager module - it simply doesnt' show.
Any clues?
All other fields show, but not that one.
It doesn't appear at first glance to be the same as the problem with the SimpleHTMLEditorField described here where the class hidden wasn't being unset by the JavaScript http://www.silverstripe.org/dataobjectmanager-module-forum/show/283202 as the HTML code isn't even being output to the popup window.
Below is the code for my data object that does this in case it helps:
<?php
class HCPFeature extends DataObject {
//database
public static $db = array(
"Title" => "Varchar(255)",
"Description" => "HTMLText"
);
public static $has_one = array(
"HeroImage" => "HCPFeature_Image",
"DeepLink" => "SiteTree"
);
public function getCMSFields() {
$fields = new FieldSet();
$fields->push( new TextField( 'Title', 'Title' ) );
$fields->push( new SimpleHTMLEditorField( 'Description', 'Description' ) );
$fields->push( new SimpleTreeDropdownField("DeepLinkID", "Links to page", "SiteTree") );
$fields->push( new ImageField( 'HeroImage', 'Image' ) );
return $fields;
}
}
class HCPFeature_Image extends Image {
function generateHeroLarge($gd) {
$gd->setQuality(100);
return $gd->paddedResize(468,220);
}
}

It almost always happens because you already have that field added to your form. Check the markup and see if there's maybe a hidden input for DeepLinkID. Try changing it to something else and you'll notice it gets added.

Unfortunately renaming this field did not fix the problem. It simply does not output no matter what it is called.
I've tried removing all other fields on the popup form to see if there was a conflict problem, but still no joy.
Can you help please?

Ok I have fixed this problem!
It was caused by having the relationAutoSetting enabled on my page, but no field for the relationship defined on my DataObject, so it was trying to use the "SiteTree" field that I wanted for the SimpleTreeDropdownField for the relationship instead and causing conflict.
Adding a new field for the relationship on my DataObject solved this problem.

Oh, excellent. We definitely need to document this. Good work!
