TabPanel not showing without refresh or resize

[Marrbacca]

Hey,
I have a complex multiple step form putted in tabpanel but I noticed that there are some bugs when I tr to open it.
If I try to access form from other cards everything appears to be working, data is loaded from stores, no javascript errors, I see every docked items but the content is not visible until I resize the window.
On the other hand, if I refresh site when on the form everything is showing correctly, even if I move out and in the form again.
As I mentioned before, form is complex it has elements I'm adding on the fly, and calling doComponentLayout.
If it's neccessary I can attach some code, but unlike the form itself the code calling the form is pretty simple.
Do anybody have some advice why is this happening?

I would use a remote debugger like weinre to see if the tabpanel is rendered and if so if it has a height.

Thanks, I checked the html rendered using Chrome Inspect
Here's how it looks

<div id="BookingForm" class="x-panel x-tabpanel x-tabpanel-dark x-fit-item" style="left: 0px; top: 0px; ">
    <div class="x-panel-body x-layout-fit" id="ext-gen1050">
        <div id="clientList" class=" x-panel x-fit-item" style="">
            <div class="x-panel-body" id="ext-gen1051"></div>            
        </div>
        <div id="ext-comp-1019" class="x-panel x-fit-item x-hidden-display">
            <div class="x-panel-body" id="ext-gen1054"></div>            
        </div>
        <div id="ext-comp-1024" class="x-panel x-fit-item x-hidden-display">
            <div class="x-panel-body" id="ext-gen1057"></div>            
        </div>
        <div id="calendarPanel" class="x-panel x-fit-item x-hidden-display">
            <div class="x-panel-body" id="ext-gen1060"></div>            
        </div>
        <div id="timePanel" class="x-panel x-fit-item x-hidden-display">
            <div class="x-panel-body" id="ext-gen1063"></div>            
        </div>
        <div id="ext-comp-1014" class="x-panel x-fit-item x-hidden-display">
            <div class="x-panel-body" id="ext-gen1066"></div>            
        </div>
        <div id="ext-comp-1016" class="x-panel x-fit-item x-hidden-display">
            <div class="x-panel-body" id="ext-gen1069"></div>            
        </div>        
    </div>    
</div>

after resizing code changes, top toolbar appears in code, and the first active item is filled.
As you can see, panels also don't have any height set.
Do you know how to fix that?

x-item-fit CSS rule may do the sizing.

@mitchellsimoens

x-item-fit not x-fit-item?
And where should I apply this rule? TabPanel?
Thanks

I'm sorry... x-fit-item

[Marrbacca]

hm, but class "x-fit-item" is present in rendered code. But there's no height and content.
I tried adding specific cls: "x-fit-item" to both panels, and tabpanel, but it didn't help :/
