JAWS没有在单选按钮上进入自动表单模式

Question

I have a form with 120 radio buttons, grouped in 30 fieldsets of each 4 radiobuttons. There is one submit <button> . There are no other inputs.

When not using JAWS, the tab behaviour of various browsers work fine. When focusing a fieldsets first radio button, the arrows jump between radiobuttons, and space bar selects one. Tab jumps to the next fieldset.

As soon as JAWS is running, when focusing a fieldsets first radio button, 'form mode' is not entered automatically. Arrows start reading characters one by one. Tab jumps to the next fieldset. Pressing enter enters form mode ('plonk') and then it works as normal.

'auto form mode' is selected in the settings and it works on other forms on the internet.

two questions:

• does anyone know why this could happen ?
• does anyone know a way to force jaws into form mode using html ?

on request: a snippet of the html

<fieldset>
    <legend>
        <h2 tabindex="0">
            Text
        </h2>
    </legend>
    <p tabindex="0">
        Text
    </p>
    <input type="radio" id="xxxx" name="xxxx" data-foo="xxx" value="a">
    <label for="xxxx">
        <strong>
            Text 
        </strong>
    </label>
    <input type="radio" id="yyyy" name="xxxx" data-foo="yyyy" value="b">
    <label for="yyyy">
        <strong>
            Text 
        </strong>
    </label>
    <input type="radio" id="zzzz" name="xxxx" data-foo="zzzz" value="d">
    <label for="zzzz">
        Text
    </label>
</fieldset>

This is not a solution .. posting it for future readers

There is one anomaly amongst form fields when it comes to forms/focus mode. Although it's possible to select a radio button without switching modes, it is necessary to be in forms/focus mode in order to use the cursor keys to cycle through the radio buttons in a group. Being unaware of this can sometimes lead to the mistaken belief that a radio group is somehow flawed.

This looks like what I am seeing. You have to actually select the first radio button to enter form mode (which then says 'plunk') before you can navigate the other options. If you don't, the cursor keys will start reading characters ('a','space','space',..) and the tab key takes the focus away from the fieldset.

So this might be 'intended behaviour' :-/
