Button to hide/show something on a form

Try the following:

<Field name='yourButton'>

<Display class='Button'>

<Property name='label' value='Surprise'/>

<Property name='command' value='Recalculate'/>

<Property name='value' value='true'/>

<Property name='Help' value='<b>Click this to reveal a new widget.'/>

</Display>

</Field>

<Field name='theHiddenWidget'>

<Display class='Text'>

<Property name='title' value='Your Surprise'/>

<Property name='size' value='15'/>

<Property name='maxLength' value='10'/>

</Display>

<Disable>

<isFalse>

<ref>yourButton</ref>

</isFalse>

</Disable>

</Field>

In my testing, theHiddenWidget remains revealed through subsequent recalculations, but I recommend you test it yourself through all the Expansion changes your form will execute.

If you want to hide it again, you'll need a more complicated Disable condition and probably a third field which acts as a toggle when the button it pressed.
