intermittend issue with events, foundsets and selectedRecord

[Hans Nieuwenhuis]

Hi,

We regular have problems like the ones below.
It happens about 3 times a week with different users.
B.t.w. the code that triggers the problem is executed hundreds of times a day for each user without problems

It looks like sometimes :

- a foundset exists, has records but there is no selected record (example 1)

- the onDataChange event does have an elementname (field) but no formname ( example 2)
As I understood from Sanneke and Johan a foundset always has a selected record, unless
it is empty.

Has anyone seen simular problems ??
I'll also create a case for this.

B.t.w. : I've put the line number on which the error is reported as comment at the end of the line !!

example 1 :

Code: Select all

Hi Hans,

we've had some strange issues when loading a dataset onto a form.
The foundset in memory showed the correct result, but the controller didn't show any records.
This had something to do with tablefilters and - as a result of this - some additional check which Servoy did in the background in order to show the correct records based on the filters.
This has been fixed in 5.2.2.

Without the tablefilters we didn't have any problem at all. Do you use tablefilters and - if so - did you try to run your solution in 5.2.2. already?

Thanks Marc,

We already use 5.2.2. We use no tablefilters. We do use Foundsetfilters, but I don't think
they are causing this.

Hi Hans,

basically, foundsetfilters should have caused the exact same effect in 5.2.1, but since you're already using 5.2.2... I'm afraid I can't be of any more help to you..

Good luck!

[jcompagner]

please try 5.2.3 there are some changes in this area.

Hi,

after installing 5.2.4 none of the issues occurred any more.

Thanks for the fixes.
