application.getValueListDisplayValue() issue

Classic Servoy
1

I have problems retrieving a value by perfoming application.getValueListDisplayValue()

For example:
Content of valuelist ‘rel_correspondence_type’:
i18n:label.letter|1
i18n:label.email|2
i18n:label.mailing|3

The valuelist is submitted to the field ‘correspondence_type’.

correspondence_type = 3

Retrieve data:
var vValue = application.getValueListDisplayValue(‘rel_correspondence_type’, correspondence_type)

vValue gets null as result.

Am I doing somthing wrong here?

Not sure but what if you add “3” instead of 3.

I guess the valuelists is formatted as a String. Adding 3 will format to 3.0.

Again, wild guessing but I would not be surprised if this is it.

(BTW you can also do 3 + “”).

Hope this helps

Seems to work for me.
What version of Servoy are you using ?
I am using Servoy 3.1.6.

I tested it. “3” or 3.0 or 3 all work.

5

Another guess, when it does not work, is the i18n label defined?

The dataprovider is an INTEGER, so that would return a 3, wouldn’t it?

Yes, the i18n labels do work fine. The valuelist is displaying the labels correctly on the form.

Hi Karel,

Can you check if correspondence_type indeed holds that value.
Like with application.output(correspondence_type)

Also when you use a value higher then the valuelist is long you end up with a null as well.

Hope this helps.

This returns 3
But when I try an Evaluate:
application.getValueListDisplayValue(‘rel_correspondence_type’, 3)
I get nothing as result. :?

Also when you use a value higher then the valuelist is long you end up with a null as well.

That’s not possible here. The user selects the value by combobox.
I use application.getValueListDisplayValue(‘rel_correspondence_type’, correspondence_type) only to set the selected value in a title bar.
So what on earth could be wrong here?

This is where it goes wrong:
if I attach the valuelist to a field on the form where I do application.getValueListDisplayValue() , the function doesn’t work.
If the valuelist is removed from the field, the function works again.

Maybe something with escaped codes or something like that?

I experienced something funny in that area as well yesterday.
So I would not be surprised if you, accidentally, hit some sort of key combination while you were doing something wild :)

Karel and I already found it.
When a valuelist is used on the field on the form then the function doesn’t work. :?: :!:

I guess some more testing is required to narrow it down some more.

I’m ALLWAYS doing wild stuff with Servoy 8)

huh.

what if you do the same from 2 different forms?

Are you trying to retrieve the info on show of the form while you setup the valuelist or are these two really different operations.

Very strange…
