Hi all,
I'm hoping you can help me.
I've been fighting with google charts for a couple of days and I'm getting
inconsistent results.
The problem
I have a table that I populate via a call to a java servlet that extends
the DataSourceServlet class and overrides the generate table method.
@Override
public DataTable generateDataTable(Query arg0, HttpServletRequest
request)
throws DataSourceException {
}
Anyhoo I create a table of data from a database, this is all working fine,
i get a nice 'vanilla' table.
Now i want to apply CSS styles to the table cell elements depending on the
data. (The data i have is transaction performance data so if its missing
the SLA i want to sent the background of the cell to red or maybe amber)
In my java code i have:
public TableCell formatPoorTxCell(TableCell cell)
{
cell.setCustomProperty("className", this.POOR_TRANSACTION_CELL);
return cell;
}
My page loads CSS with this in it
.PoorTransaction{
font-weight: bold; color: darkred; background-color: red;
}
When my table is redrawn the text is dark red but background color is not
set, so it is picking up the fact i change it to my CSS and it only loads
part of it....
The main part of JS.
function handleQueryResponse(response) {
if (response.isError()) {
alert('Error in query: ' + response.getMessage() + ' ' +
response.getDetailedMessage());
return;
}
// Draw the visualization.
var data = response.getDataTable();
var chart = new
google.visualization.Table(document.getElementById('table_chart_div'));
chart.draw(data, { allowHtml: true, page:'enable', pageSize:20,
showRowNumber: false, is3D: false});
}
If i change the java code to do the following:
public TableCell formatPoorTxCell(TableCell cell)
{
cell.setCustomProperty("style","font-weight: bold; color: darkred;
background-color: red;");
return cell;
}
The style line is a cut and paste from the CSS file, the page draws it as
expected with red background.
The problem with this is i dont want to have CSS hard coded inside my Java
code. I'd rather make it with a className so any tweaks are done via a text
file rather than having to re-compile the class every time i make the a
change.
Is this a bug or have I missed something?
Thanks in advance.
Andrew
