TMP_InputField set caretPosition regression

Using version 2.1.4:

I'm trying to add a character separator dynamically while the player is typing but its not working anymore.
eg: The user write `ABCDEFGH`, it outputs `ABCD-EFGH
Impossible to moved the caret after the last character (until canvas redraw ?).

To reproduce:

The `OnValueChange` is attached to the InputField

Code (csharp):

1.  
2.     public void OnValueChange(string value)
3.     {
4.         if (inputField.text.Length == 4)
5.         {
6.             Debug.Log(inputField.caretPosition);
7.             inputField.SetTextWithoutNotify(inputField.text + '-');
8.             // Increase Caret position
9.             inputField.caretPosition = inputField.text.Length + 1;
10.             Debug.Log(inputField.caretPosition);
11.         }
12.     }
13.  

Console Output:

4

5

Visual Output:



The same code was working perfectly before (I'm not able to remember if TextMeshPro was already on the Package Manager at that time).

 

@Stephan_B, is there a way to force a Rebuild call to `UpdateGeometry` ?

 

I'll try taking a look this afternoon and follow up as soon as I have more information.

 

@Stephan_B, did you have some time to look for this issue ?

 

Have you tried the following?

Code (csharp):

1.  
2. void OnValueChange(string text)
3. {
4.     if (text.Length == 4)
5.     {
6.         InputFieldComponent.SetTextWithoutNotify(text + '-');
7.         InputFieldComponent.MoveTextEnd(false);
8.     }
9. }
10.  

P.S. I did have a chance to look into the caret position not updating as expected and have resolved that issue.

 

Same issue with MoveTextEnd.

 

See if making the following changes resolves the issue on your end.



Note the lines numbers might be different depending on the version of the TMP package you are using.

In order for these changes to be persistent, you will need to make them in the Global Package Cache.

 

Yes, thank you, it is fixing the issue.

For the record, I identified another bug with the same sample code even after applying your fix.
If you paste the content of a string with the same code, `onValidateInput` fails because `insertionPosition` is not correctly updated with the new input.text content that was updated in the `onValueChanged`.

I'm attaching a project to reproduce:

string to enter: ABCDEFGHIJKLMNOPQRST

• result when entering each character one by one: ABCDE-FGHIJ-KLMNO-PQRST
  
• result when pasting the same string: ABCDEFGHIJKLMNOPQRST-
