Nested variables issue on HMI Webserver

Oleksandr Guminskiy

Dear All,
During visualisation development process, it was find out unexpected behavior of HMI Webserver generator.

When we attach dynamic action (Open dialog) to the button, directly placed on the HMI screen, dynamic dialog  provide
interface for attachment of variables and constants to dialog parameters. In this case all attached variables work fine within opened dialog. (See pic.1, pic.3)
But, if we want attach parameters to the same button, placed in symbol instance, variables attached to the Parameters Tab, does not work well in the Dialog.
It seems that parameters does not get link to parameters of Symbol Instance.(See pic.2, pic.4)

Is there any way to fix or bypass this issue?

Created in PLCNext Engineer 2021.0.1 (Build 4.7.1144.0)

Best regards

Hey Alexander,

I've just received the following feedback from the HMI support team:

Symbol with 'open dialog' action doesn't work when using page parameters, you are were running into an issue that should be resolved in 2021.3. 
The only workarounds until the issue is resolved are these two options:

1. don't use a symbol - just add the open dialog action to a regular button

OR

2. don't use page parameters on the dialog

So, even when the feedback is not that positive, I hope you can work with it until the issue is resolved in 2021.3.

Take care,

Frank
