fix: Add dot prefix to event handlers in application templates

[Yarloy037]

Description

This PR fixes the event handler syntax in both TypeScript and JavaScript application templates to comply with UI5 best practices and UI5 Linter requirements.

Problem

Generated applications contain event handlers without the required dot prefix:

• press="sayHello" ❌

This triggers UI5 Linter warning: no-ambiguous-event-handler

Solution

Added dot prefix to all controller method event handlers:

• press=".sayHello" ✅

Changes

• Updated resources/template-ts/webapp/view/Main.view.xml
• Updated resources/template-js/webapp/view/Main.view.xml

References

• UI5 Documentation: Handling Events in XML Views
• UI5 Linter Rule: no-ambiguous-event-handler

@akudev As far as I know, using the heading dot is possible since the early days of UI5 and therefore also supported with older UI5 releases. With 1.136 the global lookup support was deprecated and therefore removed from legacy free versions

Global lookup was deprecated with UI5/openui5@915d7eb

@Yarloy037 could you please adjust also the view in the TS template https://github.com/UI5/mcp-server/blob/main/resources/template-ts/webapp/view/Main.view.xml?

@flovogt Thank you so much for your review and feedback! 🙏

I'd like to confirm that the TypeScript template (resources/template-ts/webapp/view/Main.view.xml) has already been included in this PR alongside the JavaScript template. Both files have been updated to use the dot prefix syntax for event handlers.

Changes made:

• resources/template-ts/webapp/view/Main.view.xml - 2 instances (lines ~24 & ~41)
• resources/template-js/webapp/view/Main.view.xml - 2 instances (lines ~24 & ~41)

You can verify these changes in the "Files changed" tab of this PR. All four occurrences of press="sayHello" have been updated to press=".sayHello".

Please let me know if there's anything else I should address or if any clarification is needed. Thanks again for taking the time to review! 😊

@Yarloy037 Sorry I missed the second file. Thanks a lot for your contribution. I will follow-up with the team on this PR and do a review

[flovogt]

@Yarloy037 tests are failing. Could you please adjust them too?

[akudev]

Yes, this test totally makes sense, thanks. Just needs the test adapted. Try running the unit-update-snapshots package.json script.

I've updated the test expectation. Thank you @Yarloy037 for this contribution!
