Hi,

 

It seems that we need to reopen the bug if you say

you upgraded and still have th problem.

 

Are you generating fairly big reports?

Do you think it might be related to memory problems

in you case?

What about trying to use a different garbage-collection

policy with you JVM?

 

Thank you,

Teodor

The expression you suggested in the closed ticket isnt implemented in current version.

You said to put:

"if (expression != null)" in evaluateOld method..

I am thinking on compiling a version with that on method "evaluate".

 

Whats the common think to do ? to run the compile jasper from the server or to call them directly from the client machine ?

Hi,

 

Testing the expression for null before trying to evaluate

it was not enough for solving the problem.

So it was removed from our code. You could try it

but it might only make the problem occur rarer and not

solve it completely.

 

The bug report was reopened. Let's continue the

discussion there:

Thank you,

Teodor
