woody read only fields

[Leszek Gawron <ou...@wlkp.org>]

There seems to be a slight problem with woody if you want to work with a read
only field. You have some options:

1. use wd:output
The problem: cannot output field running if the parent is repeater and not
form. This syntax works for top level widget:

form.getWidget( "ouput_widget" ).setValue( "test value" );

but this works only for object of _Form_ type. getWidget() method cannot be
resolved for a widget so you cannot do:

var model = form.getModel();

model.output_widget = "test value";

2. use wd:field with wi:styling type="output"
You will get a value without form input control but after submission the
field's value will get reset (no appropriate parameter in request parameters)

The solution:

Introduce a new field styling : "read-only" that would render the field like
this:
<xsl:when test="wi:styling[@read-only='true']">
    <xsl:value-of select="wi:value"/>
    <input name="{@id}" id="{@id}" type="hidden" value="{wi:value}" title="{wi:hint}"/>
</xsl:when>

Why doesn't this work if the parent is a repeater? Should be something
like this:

form.getWidget("myrepeater").getRow(0).getWidget("ouput_widget").setValue("test value");

that's because the javascript widget wrapper doesn't support output
widgets. A patch for this has been provided here:

but it's not applied yet.
