Hi, I´ve seen this happen in apps with Shareable Components. Do you have many Shareable Components in your app? Thanks 🙂 // Erik ---

Yeah, just started using it - only got two now. ---

It is not directly related to function params, but in both cases when I observed this, I had Shareable Components with them. So it _might_ be related. // Erik ---

I managed to reproduce it: ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/6/6888ed294dc8415a0acc648ffdc38dc6b7e0d64c.png) If I simply duplicated ‘Stats - Row’ the error appears.

Awesome! That fixed the call stack issue. However I got a new issue 😅 This works: ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/8/8bc2855a906f4fc22ddebc57146b6b762c80156c.png) But this does not work: ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/3/385accb0e6f39650e89ae4493f5b36d098c6b196.png) This will throw this error in App Validation: ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/d/d70f04ff5bc9441498287454b76d1812d8ad85b8.png) Ps.

Can you send a screenshot of your function, and the filter on the function params? Seems like a filter on statsActivityBooking is failing. // Erik ---

Returning a plain number from a function works fine. Could be something when accessing the data source as you mention: ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/1/136bdac29784f233f7b063e8cfa2ce07fc674c82.png) ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/a/aecadf2cd3459e241162797c57af0249036e5ab2.png) ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/f/f0e3e0a5ecf6d5331e00ab754be21dd56092f9f8.png) ---

Hi! I believe I recreated it: Component param `Current` is an integer, being sent into to component, calculated with a function containing function params. _Inside_ the Component, you have a Filter, e.g. `My datasource.Maxnumber > Current` → That fails, having `Current` on the right side of a filter inside the Component, when `Current` is a function with function parameters (that parsing fails “inception-style” as a JSON with function with a function as function value is generated client side when the filter is parsed). Registering an issue on this one, but I guess you may workaround it somehow. ---

Yes, I have conditional visibility on the increase / decrease indicator icons using current and previous: ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/b/be4960266af974c558efec52e7b08a9c469bc704.png) Removing that visibility condition makes the error go away. ---

Also, using a function instead of a condition to determine visibility works. ![image](https://europe1.discourse-cdn.com/flex013/uploads/appfarm/original/2X/5/51916fe6ee6f99f4ad32c2864a98d4c8744d3c82.png) ---
