A note for BIRT's developers.

BIRT's viewer webapp that used to render (preview) the report in designer
can not find custom classes that provide the data. To do that happend i have
to create a [classes] folder in viewer's plug-in (/birt/web-inf) and put
them there.

This is not a problem in production mode but it's painfull in design mode
when you have to make changes and preview your report. Is it any workaround
about this issue. (a reference from report's project to onother open project
in eclipse's worksace, maybe)

Thanks for posting this. What I am trying to do is figure out how to
report off a previously selected list of POJOs.

Hi Stavros

Thanks for the hints! It works well except that In my case ( im
programming a design directly in java) the different row values dosent
show. For some reason only value for [0] are shown . The number of rows
is correct so the counting works but in fetch.

row["a"] = lRows[count].getA()

seems to be executed once or in any case it returns he same value all
the time.

Any hints on what it could be ?

thanks

hi anders

stupid maybe but did you increase "count" value inside the fetch method?

for example
<snip>
if (count < {your iterator limits} ){
count ++; row["a"] = lRows[count].getA() return true;
}

return false;stavros</snip>

Hi Stavros,

I got it now, I made the dataSet binding onthe individual dataitems and
not on the list to which they belong. So changing to a binding on table,
fixing resultset and adding columnhints etc it works nicely.

cheers
