Exception when reload form.

[xren]

Hi,

I created a form. There is a repeater backed from a DB table A. Then some fields backed up by the same DB table A - for single row as a resource table A'.

I am trying to have the single row resource table to do update, insert, delete.

However, there sometimes there is null pointer exception and form does not reload when I click button to trigger the work. Sometimes, the form load with buttons not show even though I set them to show();

I don't know the reason.

Thanks,
Xiaoli

Can you show your script and also show me the null pointer exception.

Kind regards

importPackage(com.ebasetech.xi.api);
importPackage(com.ebasetech.xi.services);


controls.PANEL_MESSAGE.hide();

controls.PANEL_LETTER_TEMP.show();

resources.REHAB_LETTER_SEQ.fetch();
fields.LETTER_TEMP_ID.value = fields.LETTER_SEQ.value;


controls.BUTTON_ADD.hide();
controls.BUTTON_ADD_CANCEL.show();
controls.BUTTON_DELETE.hide();

log("test after new script");

Hi,

Which version of Ebase are you running? We had a similar problem with vertical layouts which should be fixed in the last service pack.

I am not 100% sure what is causing your NullPointerException, but it maybe fixed now.

version 4.4.2.

It may related to buttons on the page and using multiple row and single row table from same DB table at the same time: multiple row for display, the single row table for insert, update, delete.

I had 4 button on the page: save, delete, new, cancel new. And after click each button, the script do the logic and control the button show or hide. It always go wrong either by nullpointer or buttons not show up as it should be.

Now I removed the 'new' button and use a field value to check weather it is a new or not new for insert or update, then it works fine.

I don't know the reason, which I still like to know. Do I need to send the exported form and script to someone?

Thanks,
Xiaoli

Hi,

You can send the exported file to Wai (looks like you have done this before) and he can forward to me.

Kind regards

Hi Steve,

I have sent the exported form to Wai.

Please let me know if there is anything else you need.

Thanks,
