Ordering the row group from a crosstab with a position variable

[kalvarez]

Hi everybody!!

I´m using the ireport 4.0, and i like it, before i used the 3.6 and i see a lot of good changes.

What I need is ordering the row group from a crosstab, i have a variable "count" to put the number at the begining of each rows and  works ok, the problem is that  number rows  of the crosstab  are in a wrong order.

The bucket expression from my row group is:

$V{Count Variable}+". "+$F{my field}
order Ascending

Where $V{Count Variable} is an integer that counts my field...and thats works Ok, but the order is wrong!!

The result is something like this, you can see that the position 10 is in the second place, not in the tenth place how is right.

 

Univ.		2004 (€)	2005 (€)
1. UNIV UA -		0	168.836
10. UNIV USEV -		3.000	0
2. UNIV UAB -		8.574	0
3. UNIV UCOR -		0	1.984
4. UNIV UG -		14.742	0
5. UNIV UJI -		50.000	0
6. UNIV UL -		0	782.855
7. UNIV UPNAV -		0	4.539
8. UNIV UPVAL -		133.100	0
9. UNIV URJC -		250.000	0
Total  (€)		459.416	958.214

Any idea?, i think there is a simple solution but i can't find it... thks!!

It looks like it's sorting alphabetically, and since you're mixing numbers and text together, it's not surprising that it's treating your numbers at the beginning as text.  So everything that starts with a "1" will come before everything that starts with a "2", etc. regardless of how many digits there are.   One way to fix it is to pad each number to the left with zeroes if you can safely predict the maximum number you'll run into:

 

0001 UNIV UA -

0002 UNIV UAB -

...

0010 UNIV USEV -

etc.

There might be a way to pass an invisible column that handles the order, in which case it might be that such a column could be interpreted as a number, but I don't have a lot of experience doing fancy things with crosstab reports, so I don't know for sure.

Thank you Carl, you´re right, the ireports treat numbers at the beginning as text but if set "data is pre sorted" even my text field is a string type, the sorting is correct, now my count variable works perfect...
