[SOLVED] Input value doesn't display. How is that possible?

Input value doesn't display. How is that possible?

This must be something utterly stupid that I've done or am doing, but I have an input with a value attribute that simply isn't being displayed:

<div class="input text required">
  <label for="Product0Make">Make</label>
  <input name="data[Product][0][make]" 
         type="text" 
         maxlength="255" 
         value="AC Make" 
         id="Product0Make">
</div>

Has anyone ever seen this before? Do I have some kind of typo that I'm just blind to? For whatever it may be worth, here's the CakePHP code that's generating this line:

<?php echo $this->Form->input( 'Product.' . $index . '.make', array( 'default' => $product['Product']['make'] ) ) ?>

I have a small form with a handful of text inputs, 1 textarea and 2 selects. None of the text input values display, but everything else is fine.

Any thoughts would be appreciated. I can't even believe I'm having to ask this question, but that's how crazy it's making me.

Solution

Argh. I knew this was going to be something beyond stupid. There was a bit of Javascript that was clearing data. The clearing was useful in other places, but I didn't know it was executing so it was a serious pain to track down. Once I prevented the clearing in this scenario, my values actually appeared. Because I was looking at the code in web inspector, I assumed that it would be a "live" view, but I guess that's not entirely true.

Thanks for your help, everyone.
