previous/next group - referring to row by position [message #499064]

Even after searching these forums for 2 hours I can't see any way to have next/previous links that can iterate through groups in a table

Background:
I've got a table with a grouping on a column in a flat data source (CSV). In the grouping header I have a graph for that group.

I only display one group in the report by having a filter set up which only displays the group that matches a parameter ("filteredGroup").

What I'd like to do:

I'd like a previous and next link that allows the user to see graphs for the previous/next group.

Firstly, I'm not sure how to get the group index (row.__rowNum doesn't seem to work for group headers.)

Secondly, once I have the index of the visible group, I'm not sure how to refer to the previous row. In fact, I can't even see how to get all values in a column (e.g. all values contained in row["key"])

e.g. if the groups are A, B, C, D and B is shown (because the report had parameter http://www/report.rptdesign?filteredGroup=B) then the prev link would have http://www/report?filteredGroup=A and the next link would have http://www/report?filteredGroup=C.

So, any ideas out there for what I want?

Not sure if this is what you want but look at the beforeFactory of the
attached example and the hyperlink on the prev/next labels.

Your code is fine if only I could load all the values of row[params["filterGroup"].value] into a JavaScript array, but I don't know how to.

I don't know the values to pre-populate the array as you have.

e.g. if only this would work:

myJsArray = [];
for (k in row[params["filterGroup"].value]) {
  myJsArray.push(k);
}

for( ii=0; ii< myJsArray.length; ii++ ){
if( row[params["filterOrder"].value] == myJsArray[ii] ){
currIndex=ii;
break;
}
}

// ... rest of your code follows

Ash,

You can make it dynamic by using a hidden table. Take a look at the
modified dynamic example.

Thanks a lot, hidden tables works!

Why does BIRT require such hackery? Hidden tables just to enumerate values across a column, global vars just to keep track of the current row number (for grouped rows).

Surely the API should be beefed up a bit to make it easier to do this sort of stuff?
