DataForm binding to PropertyGroup displayName property is throwing

[HannesT117]

Did you verify this is a real problem by searching Stack Overflow?

Yes

Tell us about the problem

At the moment, it is possible to use converters / pipes for the displayed name of TKEntityProperties, e.g. with Angular & nativescript-i18n:

<TKEntityProperty name="name" displayName="{{'name' | L}}">

Same thing doesn't work for the TKPropertyGroup. Entering something like the following as name property just gives me a blank screen:

<TKPropertyGroup name="{{'address' | L}}">

For me, this would be a really nice thing to have!

Which platform(s) does your issue occur on?

iOS

Please provide the following version numbers that your issue occurs with:

• Progress NativeScript UI version: 3.2.0
• CLI: 3.3.0
• Cross-platform modules: 3.3.0
• Runtime(s): tns-ios 3.3.0

It is not only pipes there seems to be no binding possible at all to

<TKPropertyGroup name="{{ label }}">

So only a hard coded label is possible at the moment, but translations require a proper binding.

@nicHoch confirming this one as not implemented and as binding to the name property is actually crashing the application marking it as a bug. Reproducible in both JS/TS and Angular projects.

Steps to reproduce:

• use this sample
• bind to the name property of TKPropertyGroup

Result: application will crash or show blank screen

Throwing with:

Cannot read property 'toString' of null, undefined

reproducible with plugin version 3.2.0 and 3.3.0-2017-12-7-3"
