Disappearance of UI controls in UI5 web app

[former_member194957]

Hi ,

     I have designed a simple web application using SAP UI5 and with HANA as the backend.It was fine during the initial phases, recently I found that the UI controls start disappearing when i change the value in dropdown and hover the mouse pointer over the controls.I am quite new to UI5..Can anyone say is this a known issue or a bug??

Please find the screenshots

screenshot 1- The initial view when values are not changed.

screenshot 2- UI controls disappearing with movement of mouse pointer.

Thanks in Advance,

Regards,

Tharun.

Hi Tharun

Are you modifying the model on change of the value?

If yes, please check the binding of other elements which are disappearing.

first of all i am not using any model to bind... i just store the ajax call output to an array and bind the required values in array to the respective controls...

Hi Tharun

Please try using a proper model for the application and then see if the problem still persists.

I will do that mate.. but i came to know that the problem is not with model or data. Its with the css i made.

[former_member194957]

with the same css , in IE the app works fine..!! this is something to think about, in chrome its not rendering properly..

Please check the CSS.

Certain properties in CSS3 have different prefixes for different browsers.

I have never seen this behavior before with UI5...

Are you using some fancy custom CSS / Javascript tricks to build your layout?

yes i am using custom css...!! @robin van

At first, I would try to use the standard CSS and see if the behavior still occurs. If not, you then  know it's in your custom CSS.

Furthermore, I would highly recommend binding your controls to a model. Having it not bound might 1) result in all sorts of unexpected issues related to displaying/updating values, but more importantly 2) you are reinventing the wheel

I guess this is some issue with Google chrome , In IE its working fine..!
