We are migrating our applications from PB12.5 to PB 12.6, as part of migration we are facing some issue with lookupdisplay() in datawindow expression. We have tried with the PB 12.6 build 4088. Application crashed wherever the lookupdisplay expression is used. We have tried with using the datawindow expression directly in the code, after that crashing issue is fixed but, the datawindow with lookupdisplay expression is not loaded properly.
Can you please suggest some ideas to fix these issues.?
Thanks in advance.
We had similar issues in Build 4091 with lookupvalues in computed fields.
The values are not displayed anymore.
It seems that the evaluation of the computed fields runs before the dddw are retrieved.
A workaround is to re-assign the expression again in the retrieveend event.
exp = this.Object.kostentraeger.Expression
this.Object.kostentraeger.Expression = exp
Does this match your problem?
