Is there a way to display a message from a config button's callback method? Right now I am using a readOnly textfield for that purpose. But, it is not a particularly attractive solution. In the plugin I am working on, the user clicks the "button" to read config data from a user supplied IP Address and Port on a remote device. The config data populates the remaining fields on the form. If the IP connection fails I need to tell the user. This is not a problem if the button is not used, since the regular validation routine will catch the error. But, reading the config takes place before the Save. (a little chicken and eggish)

Thanks

Not presently. I have the same requirement in the iTunes plugin (when a pairing attempt fails). At the moment I just show a hidden label (mine doesn't need to be dynamic) - it would be good to allow it to be red (it's on the todo list).

Thanks for the tip (I wasn't using the iTunes plugin). I came up with the code attached below. This works for my needs, though, like you said, red would be nice. This also demonstrates the use of a textfield in visibleBindingId...

the plugin docs wrote:You can even bind it to the value in another text field, but that’s probably of limited use.

Code: Select all

   <Field id='msgControl' type='textfield' defaultValue='0'  hidden='true'>
   </Field>

   <Field id="msgTestSuccess" type="label" visibleBindingId="msgControl" visibleBindingValue="1">
      <Label>The ad2usb configuration was sucessfully read.</Label>
   </Field>
   
   <Field id="msgTestFail" type="label" visibleBindingId="msgControl" visibleBindingValue="2">
      <Label>Unable to connect to the ad2usb. Verify the connection settings and try-again.</Label>
   </Field>


Good use-case for using a hidden text field as a binding value.
