Wrapped java.lang.ArrayIndexOutOfBoundsException

Classic Servoy
1

Sometimes I get an ArrayIndexOutOfBounds exception which outputs the quoted error in the java console

I’ve been looking at line 19 of this method, but there’s nothing around there which point to an array.
Does anyone have a clue? The code is below as well…

Thnkx a lot!

It seems the java.lang.ArrayIndexOutOfBoundsException is in our code. It seems the faulty line is: var $ds = databaseManager.convertToDataSet(globals.nav_cur_pk); ? Do you know what value is passed there when it fails ?

lvostinar:
Do you know what value is passed there when it fails ?

Nope… normally this should be a UUID. There’s only 4 places in our code on which this variable get’s set and all of them should set the UUID.

The nasty thing of this error is that it is not consistently reproducable. I will try clicking around and get the error occur.

I think I had a problem like that, too. Have you tried to pass that global in an array as in

var $ds = databaseManager.convertToDataSet([globals.nav_cur_pk]);

patrick:
Have you tried to pass that global in an array

should this solve it or is it the cause?

Anyway, the ‘globals.nav_cur_pk’ is just a string.

6

Yes, I know. But convertToDataSet expects an array of IDs… Have you tried?

patrick:

It can also receive a list of Strings so I think is not a wrong call; anyway definitely a good idea to try with array.

ok,thnkx Laurian & Patrick will try if this works…

convertToDataSet doesnt seem to be the problem
It is something in the addTab() that goes wrong.

jcompagner:

That is correct, I can confirm that.
Unfortunately it is just ‘.addTab(forms[$form])’, where $form is a string, with valid formname.

This only occurs when Servoy can’t keep up with the users navigation requests > which will do various ‘addTab’ commands in a short time…
Unfortunately I don’t have a stack trace or consistent way to reproduce this…
