I have created an app starting from a blank canvas, with a SharePoint List (with contact info) as datasource.
The idea is very simple: search for someone using dropdown controls to filter and then get all info about one particular person.
The first step (search for someone) is working well. Here is a screenshot of this first screen with the formula i used (and adapted to each dropdown of course). Results are displayed into a control gallery called 'list-result'.
Then, when people click on the "NextArrow", i want them to be able to get all info about the contact on a second screen. So, i added a FormWiever, select the same datasource as for my first screen ('champions-test') and in the property "item" i put: 'list-result'.selected.... and it doesn't work! Everytime i found a topic about that, this is the answer. I don't know why it is not working for me.
When i click on the NextArrow, i move to the second screen and there is this message "no item to display" (sorry, french traduction). And in the "back office" i got this error message: Invalid Formula. Expected a value compatible with 'DataSource'. I tried to reduce the number of records in my list (now there are less than 500). I tried to change ' ' for " ". Nothing seems to work... if anyone has an idea that would be great ! 🙂
For info, i tried to use the button "PowerApps" directly from SharePoint. If i click on the nextarrow on my list, all info are displayed correctly on a second screen. I checked their "code" and this is exactly what i try to do. Only the success is not the same 😉
