Hello, I’m using the latest version of the old framework, and I’m getting this exception when trying to enter find mode on the onRecordSelection of a form: ```auto 2012-09-04 10:26:51,722 ERROR

``` What’s weird is that if I just execute the find within the developer’s console everything goes just fine… EDIT: this only happens in webclient EDIT2: the problem seems to be related to the fact that I directly use the related foundset to perform the find, so that some update event is triggered or something…unfortunately I can’t duplicate or apply foundset filters, since related foundsets cannot be changed in any way apart from searching them… ---

It looks like this is related to this change in 6.1: > Form.onRecordSelection is also fired when the selection is being set to none (-1) if an empty foundset is set. (so foundset.getSelectedRecord() can return null) See the 6.1 changes list: [http://wiki.servoy.com/display/public/DOCS/New+in+this+release](http://wiki.servoy.com/display/public/DOCS/New+in+this+release) You should check in your onRecordSelection method if there is really a record, because that is not always the case anymore. ---

I don’t know but I’ll give it a try. However the null reference seems to be the form used by some internal method of Servoy. ---

What exactly is your code around line 65 of inail\_datigenerali\_tab.js? ---

This is the function generating the error ```auto function filterData() { var fs = ditteinailgenerale_to_ditteinailposizioni; if(fs && fs.find()) { // La data di decorrenza deve essere anteriore alla data odierna fs.datacessazattivita = '^||>=' + globals.formatForFind(globals._TODAY); fs.search(); } } ``` The error is raised by the if clause
