Caching and Indexes

Well, today I have to trouble shoot a weird problem for my customer (Ax30SP5). The problem is like this:

A LedgerTable consists of 822 records. Using the following select statements (in a job) yield different results.

a) While select ledgerTable
// work...
[This returns 822 records]

b) While select ledgerTable
where ledgerTable.accountNum >= [something] &&
ledgerTable.accountNum <= [something]
// work...
[This would only returns 278 records]

The interesting aspect of this problem is it only fails in a certain company. Yet the data in ledgerTable is the same as in other companies. Also, there's no problem if I use other fields in the where clause.

After playing around with parameters and settings I've figured:
i) If I change the caching from Entire Table cache to another type of cache, the problem's gone but this impact the performance of the system. [The problem comes back if I change it back to Entire Table cache]
ii) I can change the "Primary index" to another index to solve the problem. [The problem actually disappear even after I change the primary index back to its original one]

During the debug process I read through some articles and other resources. While I have no logical explanation on this, it seems that there's a slight chance the client side record caching would fail. Which in turn leads to problem in record selection related to primary key. [For record cache populates itself with primary key]

P.S. Anyone who has a better idea of what's happening please kindly share it with me. Thanks in advance.

Tabax for 4.0 follow up

After taking some time looking into it, I found those missing functions were due to tabax not able to find the correct image to load. The problem is the line of code that returns the path to the [DAX path]\application\share\include now returns [DAX path]\client\share\include instead. Fair enough, I just put the images into client folder instead and the functions are back.

However, the other problem regarding tabpages switching not working properly is outta my league. Hope someone can figure it out.

Tabax for DAX 4.0

Yurii has post an article on getting tabax to work on DAX 4.0. I tried it on SP1 and I had to change the security reference within assertDevelopment method also.

At this point some functions seems to be missing and the tab isn't 100% working (but close enough). It is functional but I missed many of the stuff I can do on 3.0.

It'd be nice if it's fully compatible with 4.0 in the future.
