Not Compatible with Vaadin 8.1.3

[wilsontjohnson]

Crash when exporting in Vaadin 8.1.3.

Caused by: java.lang.NoSuchMethodError: com.vaadin.ui.Grid$Column.getValueProvider()Lcom/vaadin/server/SerializableFunction; at org.vaadin.addons.excelexporter.ExportToExcel.addGridDataRow(ExportToExcel.java:399)

Suggested fix:
Change versions In the pom.xml for the build.

Vaadin 8.1 changed the getValueProvider method to return a ValueProvider.
It is still a implementation of SerializableFunction and by extension Function, so no code change is needed, just a rebuild for Vaadin 8.1

Hi,

I am using Vaadin Spring Boot Starter. Below is my gradle dependency:

compile("com.vaadin:vaadin-spring-boot-starter")

I still get this error. I even updated the dependency to
compile("com.vaadin:vaadin-spring-boot-starter:2.0-SNAPSHOT")
but still getting the same error.

I am a newbie. Please let me get out of this exception.
Thanks,

I ran this add-on with Vaadin 8.1.0 and got the same issue
"Caused by: java.lang.NoSuchMethodError: com.vaadin.ui.Grid$Column.getValueProvider()Lcom/vaadin/server/SerializableFunction; at org.vaadin.addons.excelexporter.ExportToExcel.addGridDataRow(ExportToExcel.java:399)"

For now, I went back to Vaadin 8.0.6 as Wilson suggested as above.
I am wondering when "Export To Excel" add-on will support Vaadin 8.1.0 and higher?

2 tentative solutions:

1. You can change to 8.0.6 in POM to tentative fix the issue. (To meet the addon Vaadin version)

2. Or, you can download https://github.com/bonprix/vaadin-excel-exporter to your local machine.
   a. Change that project Vaadin version in POM from 8.0.6 to 8.1.5 and then recompile it (mvn clean; mvn install)
   It should be generate 2.1-SNAPSHOT version in your local.
   b. Go to your personal project, change Vaadin version to 8.1.5
   and <vaadin-excel-exporter.version>2.1-SNAPSHOT</vaadin-excel-exporter.version>

   Then your project able use the latest local build vaadin-excel-exporter.

Myself use #2 to tentative resolve the issue.
