[OpenUI5Support]: Version 1.120 Fatal Issue due to Formatting function being renamed

[i832513]

Bug Description

Please refer to the following links:

1. https://jira.tools.sap/browse/[CPOUI5MODELS-1487](https://jira.tools.sap/browse/CPOUI5MODELS-1487)
2. SAP/openui5@cccc043

The function Formatting.setLegacyDateCalendarCustomizing is renamed in version 1.120 - it is unclear at this time if OpenUI5 will deliver a new version of OpenUI5 which provides the backwards compatibility necessary to prevent fatal page errors.

Affected Component

OpenUI5Support

Expected Behaviour

The OpenUI5Support static import should not crash the page no matter what version of OpenUI5 is being used.

Isolated Example

https://codesandbox.io/s/ui5-webcomponents-forked-5kchxn?file=/index.html

Steps to Reproduce

1. Include OpenUI5 1.120.0
2. Include OpenUI5Support feature statically

This will break the page and not load any web components.

I'm having trouble right now to get the sandbox to reproduce the issue because openui5 script is not downloading or executing - I'm not sure what i did wrong - but someone could fix that.

It seems that your sample works with 1.120.0, but if you change the bootstrap to nightly like here, it does break.

Working on a fix right now.

Hi @scameron we plan to downport this fix for 1.19 as 1.19.1

Do you need this for older versions?

[scameron]

I don't think we're waiting for this fix on our side. Did you mean to tag @i832513 instead?

Hello Scott @i832513 we plan to downport this fix for 1.19 as 1.19.1

Do you need this for older versions?

[i832513]

@ilhan007 ,
I know that the project having this issue is currently on 1.15.x - but I don't know how difficult it would be to upgrade that project to version 1.19.1 as part of the patch, if there are no major issues with that we can consider to upgrade to 1.19.1 to fix the issue.

[ilhan007]

Ok, @i832513 let me know if you would be able to upgrade or rather stay on 1.15

@ilhan007 ,
Can you please downport this to 1.17.X because we are using that version in production right now.
