Title: Updating a prompt
Post by: GFasolt on May 03, 2018, 01:39:22 PM

I am working on a wizard in which the user first selects an "Equipment Type" from a drop control on the first tab.  This works perfectly to filter another drop on another tab.  On the first drop's client side, I reset the prompt for another field (on yet another tab). Unfortunately this prompt is never updated despite the fact that the value is included in the Equipment Type view.  How do I force the prompt to reflect the value in the view?

Are you reseting the prompt field?
(Client Side Tab)

Thanks for writing.  I am resetting the prompt using the client-side reset for the drop to execute an expression in the template's Prompt field for a field on another tab.

Hi,

I can see a small amount of your prompt function:

UsageMetricText(VTP:

Lets pretend it says this:

UsageMetricText(VTP:MyField)


Usually, at this point in time your would need to use the session value not the record buffer, eg:

UsageMetricText(p_web.GSV('VTP:MyField'))

Hi Bill,

Thanks for your reply.  I sometimes struggle with knowing when to use session values, so I thought your suggestion was the fix I needed, but unfortunately not.  Checking the session value in Prompt::IRP:MilesOrHours Routine with Ultimate Debug confirmas that to value is always 0 when I am expecting 1 or 2.

Hi Greg,

Maybe make a small example (maybe change one of the shipping examples) to show what you are doing, and the effect you are getting?

You should be using SessionValues on the form (pretty much everywhere) but perhaps you are not setting the _SessionValue_ at the right time? you must set the session value not the simple variable.

cheers
