This project reveals an issue when we use SplitLayout with primary component as Spreadsheet
(Excel file with grouping) and other second one as random component (in our case is Button).
Project's skeleton was got from https://start.vaadin.com/app and used Flow/Java - Java - Maven - Spring Boot.
JDK was used as Eclipse Temurin (AdoptOpenJDK HotSpot) 21.0.3
Was used next Vaadin's version for test:
- Vaadin 24.3.12 with Spring Boot -
com.vaadin:vaadin-spring-boot-starter:24.3.12 - Spreadsheet component 24.3.12 -
com.vaadin:vaadin-spreadsheet-flow:24.3.12
When we want to use SplitLayout when Spreadsheet is primary component and some of another component will be
as second component, and we want to use Excel file as complex Spreadsheet (bunch of data with some of frozen rows)
with grouping behavior and a then after we clicked on the collapse/expand button all rows except frozen rows
become invisible.
If we try to click on collapse/expand button again the issue won't disappear.
Also, this bug reproduces when we move splitter closer to the spreadsheet (left) side and then click on collapse/expand button.
Temp workaround is, after refresh the browser tab to reset broken state, move splitter closer to opposite of the spreadsheet (right) side and after that after click on the collapse/expand button spreadsheet won't break.
NOTE: the same behavior was noticed on Vaadin 8.24.0 and Spreadsheet addon 2.1.1
(HorizontalSplitPanel with Spreadsheet as first component),
(com.vaadin:vaadin-spreadsheet:2.1.1-dspanel / com.vaadin:vaadin-spreadsheet:2.1.1)
