Hi! i have a *strange* problem with esql:group/esql:member:
when i add esql:group/esql:member to my xsp page then the loop fetching
the results from the resultset changes to an endless loop, till i get an
java.lang.OutOfMemoryError.
settings vm: -ms128m -mx256m
settings: storejanitor: freememory=10000000 heapsize=268435456
the logic of this page is: (simplified)
page
// main query
esql-connection #1
esql-pool
esql-query #1
esql-results #1
// nested query
esql-connection #2
esql-pool
esql-query #2
esql-results #2
// one more query for lookup data
esql-connection #3
esql-pool
esql-query #3
esql-results #3
/esql-connection #3
// add results to xml tree
output esql-result #2
// xsp-logic
if display-details then
// esql-query with group/member
esql-connection #4
esql-pool
esql-query #4
esql-results #4
esql-group
esql-member
// add row to xml tree
esql-result #4
/esql-member
// add
summary row to xml tree
summary-line
/esql-group
/esql-connection #5
/if
/esql-connection #2
/esql-connection #1
/page
if i use esql:group/esql:member with an simpler query, all works as
expected. and if i remove the esql:group, esql:member and summary line
from the xsp page shown above thers also no problem...
thx for any hint, chris
btw: i have attached the xsp page for reference :o)
