bug BlankScreen bug

[Daniel Prado]

Hello!

I'm using UniGUI 1.90 and facing a strange bug when using TUniPageControl. 

When I change to another tab in a pagecontrol that have a third party library (like UniSFChart - HighChart) inside it, sometimes my screen got "blank" and the entire system stop working. To get it working again I have to refresh the entire page. This error happens randomically. I've noticed that when this error occurs, this log appears in the browser console:

Uncaught TypeError: Cannot read property 'tagName' of null (link to image: https://nuvem.grvmax.com.br/owncloud/index.php/s/ues9XeRCfLIHSce )

Anyone already faced this bug?

 

Thx.

Hello Farshad.

Build 1496 (UniGUI 1.90.0.1496) with Delphi RIO 10.3.

Today I was able to get a screenshot of what happens when the error occur. Here's the link: https://nuvem.grvmax.com.br/owncloud/index.php/s/X6FLF5mQwM6XIAE

This bar in the middle of the screen preceds the error and, if I press escape, it disappear but then the system no longer respond.

Hello,

Can you please specify, which edition of UniGUI are you using?

[Sherzod]

If you are not using the trial version, then you can adjust your forum email address and attach a testcase.
