Tabs disappear on leaf nodes

[VicTK]

Hello,

I am fairly new to VMWare plugin development. And am quite a rookie.

I am facing a problem in plugin. I have created Custom views with the following objects, lets call them

A, B, C & D

Every A has a list of B's (B's appear on A's related items tab)

Every A has a list of C's (C's appear on A's related items tab)

Every A has a list of D's (D's appear on A's related items tab)

The tabs appear correctly on the A work space, but when I go to B, C or D workspaces, the tabs disapper I just see a grey space, where the tabs supposed to be present. 

Also, I if I browse on the left navigation panel, the flow works correctly. If I browse using the double-click on the table items in the right, the Left Navigation disappears for B, C and D.

My plugin XML is attached

<?xml version="1.0" encoding="UTF-8"?>

Hi, VicTK,

Thank you for your interest in the vSphere Client SDK.

I would advise you start with minimum code and just modify it step by step.

It may be quite complicated if you introduce 4 object types all at once.

The SDK team may not have much capacity to fully investigate each use case in details described in the forum.

In your case I would start by taking a look at Chassis B sample which deals with 2 object types and their relation.

Having said all of that I would point out to something that I have noticed in your plugin.xml with regards to the related items:

You have defined just one relation for type A

    <extendedPoint>vise.relateditems.specs</extendedPoint>

while you need also the relation described for the other directions

You should also make sure that your server side data adapter knows about all the types.

If you want to get deeper in that route it will be really beneficial if you investigate Chassis B sample.
