I am developing a web based solution for a client that prefers to enter records into the system like it is done in Excel so that in a single click of Submit , several rows in the database can be updated at once. Now i want to build a multi dimensional array of Textfields that maps to multiple rows in a database. I built this once in Servlet and JSP where a loop wipes accross the request.getParameterMap() and updates each corresponding row/column in the database.

 

Now looking at Wicket, what will be the neatest way to get this done. I could create so many textfields like

//Column 1

TextField A1 = new TextField("A1");

TextField A2 = new TextField("A2");

...

TextField An = new TextField("An");

 

//Column 2

TextField B1 = new TextField("B1");

TextField B2 = new TextField("B2");

...

TextField Bn = new TextField("Bn");

 

Now my Bean Model will have to contain a field each for all these textfields. is it?

 

Except its not neccesary, but for these kind of problem, is it possible to have a feature like this: ,

maybe,

 

TextField[][] fields = FormComponentUtilities.createGrid(row,column,fieldsModel); //model must be 2D array

form.add(fields);

 

then in my model object, I have,

 

private String[][] fieldsModel;

 

When I submit the grid, i cant simply work the 2D array to update the backend.

 

 

If this feature will not be neccessary, what better way can i go about it?

 

thanks
