Problem with scrollable checkbox not retaining selection

I have a curious problem with scrollable checkboxes.

I had a number of standard dropdowns, populated on form load with data from an underlying SQLServer database, and that worked perfectly. I was asked to make them multi-select dropdowns, which translates to a scrollable checkbox. I did that, linked them to the action/DB service that populated the previous dropdowns, and now they don't work so well.

What I'm seeing is that the scrollable list is populated on form load as the previous dropdown was, but when I select an option from the list the form 'reloading' indicator comes up to indicate that the form is talking to the server, and anything I selected in the scrollable checkbox is unselected when the form refresh is complete. The rest of the form is as I left it.

I'm on Orbeon 4.8.0.

Hi James,

Are you saying that the reload indicator stays "stuck", that is the doesn't go away when you select something in the scrollable checkbox list? What do your service/action do? Are they just running just when the form loads, or also when a selection is made?

Re: Problem with scrollable checkbox not retaining selection

Alex,

No, the reload indicator is behaving as normal. I see it flashing happily away in the top left of the screen every 30 seconds or so.

I have a database service that selects two columns from a database (probably 50 rows of information). There is an action that uses that to populate the label/value pair in a scrollable checkbox. The action was set to trigger on form load, run always. Set like that, it happily populates a dropdown menu from which I select a single value. It will also populate a scrollable checkbox, and if I'm quick I can select multiple values, but as soon as the reload indicator flashes the checkboxes in the scrollable checkbox get reset. When it was a single-choice dropdown menu, it worked as expected, with no resetting of the selected value.

I tried setting the action to trigger on form load, and run on creation only, and the scrollable checkbox doesn't get populated at all, althought it will now let me set multiple checks from the 'first choice, second choice, third choice' defaults, and it doesn't reset them when the reload indicator flashes.

Hi James,

First, you don't want to mark an action you use to populate a selection control as running on creation only: the choices are not persisted with the data, so if you don't run the service at least on every form load, when users edit existing data, the list will be empty.

I am trying to reproduce this with this form: https://gist.github.com/avernet/960c1d46d6cab757e1b4. Things are working for me, but you have to be careful: the values for your choices must be different, and must not contain any space. The issue you're describing sounds like something that would happen if you have spaces in the values. If the values "naturally" have spaces, you can replace the spaces by some other character, as done in the sample form linked above. Could that explain your problem?

Re: Problem with scrollable checkbox not retaining selection

Alex,

The values do have spaces. Assuming that the PDF shows the labels of the selected choices rather than the values (and I haven't tried to produce one to check), replacing the spaces would be OK for this application, but not for everything we're planning

I'll try that and let you know if it works.

Thanks,
James.

Hi James,

OK, if your values have spaces, I would say that this is very likely the reason for the problem you're seing. You'll let us know if replacing the spaces by some other character works for you.
