Getting the footer only on the last page

Hey,

I am trying to get the footer only on the last page of my pdf.

I have to generate a pdf file.My birt picks the data from the flat file(tab seperated file) in a table and displays it.
But the page where the table ends (it can extend to more than one page)is the last page of my pdf and I want to display some information in the footer of this last page reading it from the report parameters.

How can I implement this?

I tried it by writing the script in onRender() of the footer component.
if (BirtComp.lessThan(pageNumber, totalPage))
{
this.getStyle().display = "NONE";
}
But this does'nt works in my case. Since,I need to run birt only in one phase.

Setting column decimal format with Java Design API

Hi, I am trying to set the format of a numeric cell using the Design API to 2 decimal places to no avail.

I have tried the method suggested by the following post : Changing column decimal format with the DE
to no avail.

My code looks like this:

String colFormat="#0.00";
DataItemHandle dih =(DataItemHandle)cell.getContent().get(0);
NumberFormatValue nfs=new NumberFormatValue();
nfs.setPattern(colFormat);
dih.clearProperty(StyleHandle.NUMBER_FORMAT_PROP);
dih.setProperty( StyleHandle.NUMBER_FORMAT_PROP, nfs );

but to no avail. It formats the string 1 only as "1.0" instead of "1.00" as I would expect.

I took a look at what was in the report design file and the XML for the column looks like this:

 <cell id="341">
                        <property name="paddingBottom">0.1pt</property>
                        <data name="data_ratio" id="342">
                            <structure name="numberFormat">
                                <property name="pattern">#0.00</property>
                            </structure>
                            <property name="textAlign">center</property>
                            <property name="height">8pt</property>
                            <property name="width">24pt</property>
                            <property name="resultSetColumn">ratio</property>
                        </data>
                    </cell>

Does anyone have any ideas?

Thanks.

how to linkage 2 data between each other

Hi, I need help linkage between these two.
1. It would be a table because it is from another data set. It has own data to retrieve it detail. It can have one, two or three records. The problem is how can I link it to another table details row?
eg. Cash | Credit Card | Voucher. It can be more based on the data. Which means it is not hard coded/Label. It would show/retrieve it in horizontal row.
2. It needs to link it on the top data set because it needs to know the details row from another table whether the column database "totalamount" column is cash, credit card and etc etc from the details row (1.).
How to determine it?
Do you all have any suggestion to settle this problem?
thank you for your help.
Greatly appreciated.
Here is the blueprint I would like to show you.

Hi All,

I am using BIRT runtime 2.5.1. My problem is. i am using 5 table groups and when i am trying to preview the report its giving me error.

Is there any limitation on table group that we can use only 4 groups and not more than 4 groups.

Such kind of error i am getting when there is no data. Because if there is a data available then all 5 table groups are working fine. Problem is only when there is no data available to render report.

Please reply with proper answer

Edit Data Set

Hello,

When i right-click on my dataset and select 'Edit', the Edit data Set window pops up.

I only have 6 options in this window: Data Source, Output Columns, Parameters, Filters, Settings and Preview results. (see screenshot as attachment)

In manuals on how to build reports in BIRT, i see there are more options in this window like Query, Computed Columns and Property Binding.

How do I get these extra options? Because now I have to put my SQL into the Open method and define the columns in the fetch method and then define the Output Columns before I can get a result... Or am I missing something here (I just started making BIRT reports a few days ago..)

Eclipse Platform
Version: 3.7.1



Thank you in advance.

removing duplicates without using suppress duplicates

Hello everyone, I have use the suppress duplicates and it works fine for string but in my case I have also duplicates in numbers (counts) which I have to remove, I just have to retain the original.

I have result like this:

group |owner| count
-------------------
data1 | abc | 3
data1 | def | 3
data1 | ghi | 3
data2 | eee | 1
data3 | fff | 1
data4 | ggg | 2
data4 | hhh | 2

I have achieved this using suppress duplicates in column 'group':

group |owner|count
-------------------
data1 | abc | 3
_____ | def | 3
_____ | ghi | 3
data2 | eee | 1
data3 | fff | 1
data4 | ggg | 2
_____ | hhh | 2


but when I use suppress duplicates in 'count' column it shows like this:

group |owner|count
-------------------
data1 | abc | 3
_____ | def |___
_____ | ghi |___
data2 | eee | 1
data3 | fff |___
data4 | ggg | 2
_____ | hhh |___


the count for data3 is gone too using suppress duplicates in 'count' column because count from data2 and data3 are both '1'

What do I do now? how do I remove the duplicates that will not affect the next row?

Thanks in advance and more powers!

I need to show the difference between the salary element in the attached pdf instead of the sum
I added the sum using Total.sum(row["SalI1"])
I need to replace this with the subtraction

I tried adding in salI1 expression 
a = dataSetRow["SalI1"];
 if(dataSetRow["calculatedperiodcode"] == 'Monthly 3-2013')
 a = dataSetRow["SalI1"]* -1;


but the display of the first row showed the negative sign, If I can make negative sign invisible but internally available this will solve the problem

		csvOptions.setExportTableByName("data");
		
		csvOptions.setDelimiter("\t");

		csvOptions.setReplaceDelimiterInsideTextWith("-");

Parameter scope/visibility with scripted datasets

April 24, 2013, 10:21 am
$

Hello,
I have a report setup that uses a combination of a cascading parameter group and a separate boolean parameter represented as a checkbox. The cascading group populates based on script datasets backed by java classes.

Functionally the report provides a list of customer orders and the cascading group lets you select a company, division, then list of customers. The check box controls whether or not closed orders are included in the report. All of this works fine when submitting the parameter set to generate the report.

I've now got a requirement to retrieve my list of customers based on the setting of the "include closed orders" checkbox. This is because some customers may not have any open orders, to controlling the list of customers you see during the parameter loading is needed.

My problem is that the current value of all the report parameters don't seem to show up in the report context when I am inside the backing java classes. The current values of the cascading parameters are there, but the current state of the checkbox is not. The parameter is there, but is left at the default value. It's only when submitting the entire report request that I see the current value of the checkbox.

Is there any way to get access to these current parameter settings while in the middle of the cascading operations? If not, does anyone have suggestions on how I can accomplish this?

Thanks for any input or advice you can share.
