i have the following problem:
I have a Tabs page with 8 Tabs. 4 of them are enabled per *ngif=“variable” and the others disabled (per ="!variable").
What i want to do is toggle the visibility of the tabs per button click (hide the 4 active ones and show the 4 inactive ones).
I am using a button to change the variables value. When i do this, all 8 tabs appear in the tab bar and whenever i click on any of them i get the following error:
ERROR TypeError: Cannot read property 'length' of null at Tab.NavControllerBase.getActive (nav-controller-base.js:933) at Tabs.select (tabs.js:329) at Object.eval [as handleEvent] (Tabs.html:1) at handleEvent (core.js:13255) at callWithDebugContext (core.js:14740) at Object.debugHandleEvent [as handleEvent] (core.js:14327) at dispatchEvent (core.js:9704) at core.js:12028 at SafeSubscriber.schedulerFn [as _next] (core.js:4235) at SafeSubscriber.__tryOrUnsub (Subscriber.js:238)
What might be the reason behind it? I cannot seem to understand.
