Problem with hidden listgrid field on Canvas.showPrintPreview

[mgbf]

Hi!

My application has a listgrid whose first column is a checkbox, where users can select records for printing (see my_app.jpg).

When users click the print button, I have the following code to hide this column and print the grid:

btnPrint.addClickHandler(new ClickHandler() {
  @Override
  public void onClick(ClickEvent event) {
    myGrid.hideField("checkboxField");
    Canvas.showPrintPreview(myGrid);
    myGrid.showField("checkboxField");
  }
});

The problem is that the print preview window just hides the checkbox column for the first 100 records, as you can see in hidden_field_print_preview.jpg. After that the checkbox is still visible in the preview.

My grid has the following properties:

myGrid.setShowAllRecords(false);
myGrid.setDataFetchMode(FetchMode.PAGED);
myGrid.setDataPageSize(100);

We can see that the grid is paged by exactly 100 records. But the print button is only visible when mygrid.getResultSet().allRowsCached() is true

Is that a bug or am I doing something wrong? Do any of you have a better idea about how to hide a field for printing?

By the way, I'm using latest smartgwt (2.4).

Best regards,
Matheus
