Divide by Zero Exception in Searchable

[robert]

I updated the jide oss lib to 2.7 from 2.6 and now I get the exception listed below. Nothing in my code has changed. If I revert back to 2.6, the exception goes away. Is this a Jide bug, or is this something I need to handle in my code somehow. I looked at the Jide code for TableSearchable.setSelectedIndex, and I don't see any difference between 2.6 and 2.7, so I'm a bit confused as to the cause of the exception. Thanks

Code: Select all

Exception in thread "AWT-EventQueue-0" java.lang.ArithmeticException: / by zero

While doing some debugging I found that the exception only occurs with setMainIndex(-1). If I comment out that line, the exception does not occur. I'm guessing it is related to this change:

(Common) Fixed the issue that TableSearchable cannot search correct result while setMainIndex(-1) and highLightAll in SearchableBar.

Can you please check if yourTable#getColumnCount() returns 0 when the issue happens? I don't think it is related to that fix so far. The reason that setMainIndex(-1) changes the behavior is because the parameter setting changes the flow of the logic.

One more question, which release worked for you in 2.6.x?

Thanks,

Yes, the getColumnCount() does return zero, but there is no exception thrown in earlier Jide versions.

I was using the most recent 2.6 release (2.6.7), and no issue occurs. Switching the lib to 2.7.2 causes the exception. I can't see where to download the earlier 2.7.x releases in order to isolate the problem. Java.net seems to only have the most recent release in each 2.x branch.

As already mentioned the problem only occurs when I include setMainIndex(-1) in my code. If I set the index to another value, the problem does not occur. I have also found that if I move the setMainIndex(-1) line further down in my app constructor to where the getColumnCount() is greater than zero, the problem does not occur.

So, I can solve this issue in my code, but there seems to be a change in 2.7.x that caused the exception to suddenly appear.

I will add a protection here anyway in next release.

Just so you know, this is fixed in 2.7.3 release.

Thanks,
