DropDown.enabled bug in Omnicore App SDK

Fritz · January 2021

There seams to be bug in javascript library with "enabled" property of DropDown component. It will generate error on html page:

"Document Load event routine failed. >>> TypeError: Unable to get property '_enabled' of undefined or null reference"

Code in Load event, that generates it, is following:

drpLoggingLevel = new FPComponents.Dropdown_A();

drpLoggingLevel.model =

{

items:

[

"Silent",

"Brief",

"Verbose",

"Debug",

]

};

drpLoggingLevel.selected = 2;

drpLoggingLevel.onselection = doOnLoggingLevelChange;

drpLoggingLevel.enabled = false; // bug in API ? - will generate error

drpLoggingLevel.attachToId("LoggingLevelDropdown");

OK, solved it immediately by myself.

Writing "enabled" property must be AFTER attaching component to DIV element:

drpLoggingLevel.attachToId("LoggingLevelDropdown");

drpLoggingLevel.enabled = false;

It might be still bug, as all other components will work either way.
But at least workaround for now.
