Re: Change text of buttonCell in celltable

Hi Thomas,

Could you pls elaborate a bit. My code is as follows

Column<HotelSearchDTO, String> bookCol = new Column<HotelSearchDTO, String>(new ButtonCell()) {

@Override

public String getValue(HotelSearchDTO object) {

return "Normal";

}

}; 

bookCol.setFieldUpdater(new FieldUpdater<HotelSearchDTO, String>() {

@Override

public void update(int index, HotelSearchDTO object, String value) {

// How to return "Loading..." from this place as this is the only place to handle click event.

}

});

Thanks

Deepak

Hi,

I have a celltable which has one column as ButtonCell.

I am doing some server side work on click of this button. 

Now, i want that the text should change to 'Loading...' when clicked on this button and should again to its original text after i finish server side work.

The point is to show the user that the click has happened and to wait till work in progress.

col.setFieldUpdater() has nothing to achieve this.

Can you pls give me some solution ...

The "correct" handling of that situation would be that the column's getValue can return either the "normal" button text or "Loading…", so that it still "works" in case the table is redrawn midway 'til the server responds.

Once you have that, you only need to trigger a redraw of the raw whenever the value ("normal" text vs. "Loading…") changes.
