We're running into an issue with the SfTextInputLayout control:

<textInputLayout:SfTextInputLayout ContainerType="Outlined"

Hint="Enter your E-mail Address"

LeadingViewPosition="Inside"

CharMaxLength="128"

ShowHelperText="False" ContainerBackground="#211f32"

HeightRequest="85" Margin="0, 20">

<textInputLayout:SfTextInputLayout.HintLabelStyle>

<textInputLayout:LabelStyle TextColor="White" FontSize="14" />

</textInputLayout:SfTextInputLayout.HintLabelStyle>

<Entry.Behaviors>

<behaviors:TextValidationBehavior

BindingContext="{Binding BindingContext, Source={x:Reference Entry}}"

InvalidStyle="{StaticResource InvalidEntryStyle}"

ValidStyle="{StaticResource ValidEntryStyle}"

Flags="ValidateOnValueChanged"

IsValid="{Binding Validation.IsValid}"

MinimumLength="4"

MaximumLength="128"

RegexPattern="{x:Static expressions:EmailAddressExpression.Default}" />

</Entry.Behaviors>

</Entry>

<textInputLayout:SfTextInputLayout.LeadingView>

</textInputLayout:SfTextInputLayout.LeadingView>

</textInputLayout:SfTextInputLayout>

</VerticalStackLayout>

---

When the scene is unloaded and reloaded at a later point, and the text/binding is updated, the following exception is thrown:

```

System.ObjectDisposedException: Cannot access disposed object with JniIdentityHashCode=199610423.

I haven't seen anything when consulting with Grok, so I wanted to report it here.

Note that switching from xmlns:textInputLayout="http://schemas.syncfusion.com/maui/toolkit" to xmlns:core="http://schemas.syncfusion.com/maui" works as expected, and no error is thrown.

So this error seems to be in xmlns:textInputLayout="http://schemas.syncfusion.com/maui/toolkit"

MK Manikandan Kannan Syncfusion Team January 8, 2026 10:09 AM UTC

Hi Mike-E,

We have created a sample using the XAML code you provided and tested by unloading and reloading the TextInputLayout. The issue could not be reproduced, and no exceptions were observed during our testing. We have attached the sample file for your reference, please review it and modify it to replicate the issue so we can assist you further.

Additionally, could you please share how you are performing the unloading and loading of the control in your implementation?

Best regards,

Manikandan Kannan.

Hi Manikandan thank you for your reply and please pardon the delay in getting back to you. I have not been able to look into this issue further and our workaround with the other namespace is working as expected without error, so that is our remedy for now. :) Thank you again for all your amazing efforts over there. Happy New Year.

PR Preethi Rajakandham Syncfusion Team January 28, 2026 06:07 AM UTC

Hi Mike,

You are welcome. We are glad to hear that the solution was effective on your side.
