Issue with an App

I have two inputs, one is my population input and the other one generates an output that I need to use to automatically update the Random Sample %. However, I am not able to do this, even though I have selected Update value by default with the action tool and selected "10" which is the default % set up.

I cannot upload the original workflow and data but I have generated a similar version for asking this question. The number 53 is not always the same. I mean, it is coming from different sources of data therefore depending on the input that I am using, it will be 53, 40, 20,1...any number. And here is where I have the problem, because the app is not picking up the new one, it takes the one that I used to configure the app.

I would appreciate any help on this regard

Thanks!

Hi @iocana ,

I've made a slight change to enable the first dropdown to be correctly populated. You currently don't have anything populating the dropdown as you have not pivoted the data to column header per value.

It's a quirk of the dropdown tool that the values that are available for selection from an incoming source are taken from the headers rather than column values.

This now should work.

Hope this helps,

Many thanks for this M!

I tried this before, the problem is that the number 53 is not always the same. I mean, it is coming from different sources of data therefore depending on the input that I am using, it will be 53, 40, 20,1...any number. And here is where I have the problem, because the app is not picking up the new one, it takes the one that I used to configure the app. Any idea with this?

Hi @danilang

Many thanks for this. It makes sense and I understand now what it is happening. Considering your solution, if I select from external source, I understand that this cannot be done within the same app? I mean I cannot have the recommended sample size that I want to use to update the Random % Sample in the same workflow than my total population + random % sample + final output right? I would have to create to apps?

thanks!

If the Input file comes from an external source and is always in the place, you can simply change the location in the UI tool. If the input file is generated as part of workflow, then you'll need a Chained App. Part 1 generates the Dropdown list and stores it somewhere accessible such as the %Temp% directory. Part 2 runs the rest of the workflow with the UI tool reading from the newly generated file.
