Symptoms

Multi Select controls and Expressions not rendered consistently in IE 11
 

Diagnoses

Multi select controls are not rendered properly in IE 11 and Chrome. We can see the Available Values section (left) but not the Selected Values section (right).


Also, we are trying to format a Date Time value using an expression to render as dd/mm/yyyy format. However, the result is rendered correctly in Chrome while in IE 11 the formatting does not apply.

 

Resolution

1_ we have seen errors indicating to the css are being retrieved as text/html and not text/css "css was ignored due to mime type mismatch" which led the controls not to render correctly
we used these URLs to clear the cash :
smartforms url]/Designer/CacheControl.ashx?m=Clear
smartforms url]/Runtime/CacheControl.ashx?m=Clear

_2 The client was applying the date format on a text property holding dates and this is not the right way, converted the text to date and applied the format, this has resolved the issue.
