Unexpected boolean behaviour

[fnanfne]

Hi Power People

I have a Gallery displaying a SharePoint List and a TextInput control serving as a search box for this Gallery.

For privacy reasons, only a single item being searched for, should be displayed in the Gallery.

I have attempted to address this requirement by covering the Gallery with an opaque Rectangle. Only when the TextInput search box has more than 3 characters, will the Rectangle disappear, revealing the whole Gallery, which should now only contain a single item. Here is the code on the Rectangle's OnVisible property.

If(Len(TextInput.Text) < 3, true, false)

This works great! Until it unexpectedly doesn't, albeit only briefly. Infrequently, the Rectangle is invisible, even though the TextInput field is empty (<3 characters)

How is this possible?

===================================

A little more background (optional)

If you want, do reference an old post I made trying to find a solution to this requirement here, which I thought I resolved. The simple boolean above also has a Timer control which I omitted for brevity. This is another measure I employed, by delaying when the rectangle disappears.

If(Len(TextInput.Text) < 3, true, 
If(Timer.Value = 0, true, !varDelayOutputTimerUp))

As a final measure, I have added 10 dummy entries into the list, and am sorting this list by Title. So even if the Rectangle is invisible when it shouldn't be, only information that is not sensitive is shown. However, I have seen at least once so far, where I have entered two characters, and the rectangle disappears, again how is this possible?

Another idea I had was to use checks to see how many items is in the list when the search is complete, if more than one item is in the list, the the rectangle will remain visible. Here is the code I thought of using

If(Gallery.AllItemsCount > 1, true false)

I feel like I'm overcomplicating things again.

Any thoughts appreciated!

@fnanfne glad and relieved we have a solution. I genuinely began to think there was something obvious I was missing about this 🤣

Probably you did the same but sometimes Powerapp do work strangely. I did face some instance like that.

i just delete the control and add it back . same code but when i add it back it works as expected
