Title Body

I am stuck in a problem with GWT CellTable. I need to create celltable dynamically and I dont have entity (Bean) class to do so. I have seen all the examples of celltable and searched a lot to do so without entity class. I need to populate table dynamically according to some metadata stored in database. I am able create table structure Consider there are two classes one is GRID and another is COLUMN for the metadata and columns definition. GRID will have list of COLUMNS as a columns definition Class GRID { List<COLUMN> columns; } Class COLUMN { String columnName; } Now i need to get grid from database and loop the columns to populate the cells (Columns) like : com.google.gwt.user.cellview.client.Column<String, String> textColumn = new Column<String, String>( new EditTextCell()) { @Override public String getValue(String object) { return object; } }; Now, I need to add some data to the celltable. but without entity there are no example how to populate the different columns. I have tried my self like : (Consider Grid have 3 columns) List<String> data; String a1 = "A1"; String a2 = "A2"; String a3 = "A3"; data = new ArrayList<String>(); data.add(a1); data.add(a2); data.add(a3); final AsyncDataProvider<String> provider = new AsyncDataProvider<String>() { @Override protected void onRangeChanged(HasData<String> display) { updateRowData(0, data); } }; provider.addDataDisplay(grid); provider.updateRowCount(data.size(), true); I am able to produce the output like : A1 A1 A1 A2 A2 A2 A3 A3 A3 </p
