CellTable question

[GeorgeS]

I'm working on an GAE app using GWT and I'm running to a problem using
CellTable. I don't know until run time how many columns are needed and
their type in my CellTable (Note: there are always two fixed columns)
so I can't just hook up the columns at design time. The values I'm
reading are currently three strings where the third string gets parsed
into however many columns I need (just a simple split into a String
[]). Is there a way to do this? I'm still learning Java so I'm
thinking there is some very simple way that I haven't discovered.

I see mention of a DataGrid in 2.4? Is there any documentation on this
yet?

You just have to read whatever information you need and then just call yourCellTableInstance.addColumn(...) as needed

I think what I'm not understanding is how to create the getValue
portion of the column creation before I add the column to the cell
table when it isn't pre-defined. When I have code like:

TextColumn<ResultDocument> fieldsColumn = new
TextColumn<ResultDocument>() {
@Override
public String getValue(ResultDocument resultDoc) {
return resultDoc.documentFields;

}
};

I can see easily what to do but when that column is accessing the (for
example) 8th value in a String [] then I can't see it. This is
probably my newness to Java (again).

To clarify... there are 1-n entries where I have no what n is until
runtime so I can't hardcode stringValue[8]...

[Jeff Larsen]

when you build the column, specify the number

MyTextColumn extends TextColumn<String[]>{

public MyTextColumn(int index){ 

  this.index = index;

}

public String getValue(String[] strings){

  return strings[index];

}

Thanks... I think that what I was looking for. I had also thought of
creating an array of TextControls but this looks much cleaner.

Jeff, that worked like a charm! Thanks for helping me make it up the
Java curve!
