Hello.
I'm having an issue with MaterialDataTable (using rc2). It always crashes
with: Cannot read property 'insert_37_g$' of undefined. This happens when I
try to add a column like table.addColumn(new TextColumn<ContactInfo>() {
... }, "Column");.
Does anybody know why this is happening ?
Thanks in advance
MaterialPanel panel = new MaterialPanel();
MaterialLabel title = new MaterialLabel("Contact Information");
title.setTextColor(Color.BLUE);
title.setTextAlign(TextAlign.CENTER);
title.setFontSize("36px");
title.setFontWeight(FontWeight.BOLD);
panel.add(title);
panel.add(new Hr());
MaterialDataTable<ContactInfo> table = new MaterialDataTable<ContactInfo>();
table.setHeight("90%");
table.setUseStickyHeader(true);
table.setUseCategories(false);
table.setUseRowExpansion(false);
table.setSelectionType(SelectionType.NONE);
table.setRedraw(true);
// ... If removing table.addColumn(...) and adding to panel at this point
it works, an empty table appears.
table.addColumn(new TextColumn<ContactInfo>() { // The point where
exception is thrown.
@Override
public String getHeaderWidth() {
return "20%";
}
@Override
public Comparator<? super RowComponent<ContactInfo>> getSortComparator() {
return (o1, o2) ->
o1.getData().getFamilyName().compareTo(o2.getData().getFamilyName());
}
@Override
public String getValue(ContactInfo object) {
return object.getFamilyName();
}
}, "Family Name");
// ...
panel.add(table);
