Preview shows FK Dropdown, but not on form 24 Jul 2014 03:16 #12527

When I add the FK to the form, the preview shows a combo dropdown list to select from the other table:
<select name="my_foreing_key" id="my_foreing_key">
	<option selected="selected" value="">- Select -</option>
	<option value="1">Item 1</option>
	<option value="2">Item 2</option>
	<option value="3">Item 3</option>
</select>

However, the Sandbox renders an empty text box.
<input type="text" size="32" value="" name="jform[my_foreing_key]" id="jform_my_foreing_key">

What is wrong? :(

Simple
This is because you must open the node (in the fields tree) of the FK, and drag a sub field in the form.

No, because it needs to know wich text value to display in the combo.

A possible improvement would be to use the default field of the table (yellow star), but I prefer that you understand the whole process, and also have a more customizable way.

This is what you call a component builder. I was able to master using this in a very short time and the resulting component works like a charm. Not just a basic component builder but a fully working component builder with forms fields tables all ready to go. You can make the list and item views to display in the front and back end. Also there is a great forum just starting to evolve and I'm sure this will grow very rapidly when you all realise how good this tool is.
