Re: Selecting TextInputCell

Sorry, I rushed a little bit. The new cell should be able to handle null values properly. Here is an updated version:

public class SpiralTextInputCell extends TextInputCell {

// Default value

private int startIndex = 1000;

public SpiralTextInputCell() {

}

/* When we have more than one DataGrid on a page, their tab indexes will collide.

 * To prevent this, we should use a different start index for each grid after the first one.

 */

public SpiralTextInputCell(int startIndex) {

this.startIndex = startIndex;

}

@Override

public void render(Context context, String value, SafeHtmlBuilder sb) {

ViewData viewData = getViewData(context.getKey());

if (viewData != null && viewData.getCurrentValue().equals(value)) {

clearViewData(context.getKey());

viewData = null;

}

String s = (viewData != null) ? viewData.getCurrentValue() : value;

if (s == null) s = "";

int tabIndex = startIndex + context.getIndex();

sb.appendHtmlConstant("<input type=\"text\" value=\"" + s + "\" tabindex=\"" + tabIndex + "\"></input>");

}

}
