The current Vaadin excel export add on works perfect for a Tree with multiple root nodes and children.
If a Tree has nested nodes, it misses out grouping and also omits out the nodes.
For ex:
Root
+child1
+child 2
+subRoot
+subchild1
+subSubRoot
+subSubChild
Root1
+one more child
In the above scenario, the excel export does not export the subchild1,subSubRoot and its children.
I did debug through the ExcelExport class and the addHierarchichalRow method seems to be considering only the rootIds.
Has anyone done something like above.
Thanks for looking into the post.
