Dropdown list with custom All Values option

[Former Member]

Hi,

We are running VC on 7.4 SP2. I have a dropdown list which gets its' values from a BW query. This works great except that I want to add a custom entry which selects all values.

In BW you would do this by setting the selection variable to "" as in nothing specified/empty. This is also the default setting in VC (you made no selection so you will get all results) but once you select something this can not be deselected.

So the idea is to add a custom entry All with value "" but apparently this gets send to BW as """" which is not a valid value. VC does not allow to use an empty value field.

So basically I am stuck here. Any of you found a solution to this problem?

regards,

Matthias

Hi Matthias,

I see your point. I could suggest two options:

1. In the dropdown input control, delete the value. Then press submit.

This works fine, only we don't get the empty value in the list.

2. To have the empty value in the list, like this:

Add to the entries of the list:

Then edit the mapping to the service to convert * into an empty string:

Thanks,
