Another way of getting this to work (at least in version 6.3.0) is to use a ternary expression which returns Boolean.TRUE or Boolean.FALSE.
For example if your existing expression was:
$F{SHOULD_SHOW_HYPERLINK}[/code]You could replace it with this.
$F{SHOULD_SHOW_HYPERLINK} ? Boolean.TRUE : Boolean.FALSE[/code] -
This is how I'm using multi-select input controls.
Create a Parameter, giving it a name and assigning the class java.Util.Collection. You can assign default values by using an expression like java.util.Arrays.asList(new String[]{"value1","value2"})
In your query, in the where statement place 'WHERE $X{IN, DB_FIELD, PARAM_NAME}' You could also use this syntax elsewhere in the report.
So my query may end up looking like:
SELECT id, metric
FROM ex_table
WHERE $X{IN, id, id_list}

Awesome! Thanks Thomas!
Haven't tried to implement yet but based of the property description this will save me tons of time.

Is it possible to detect the export format that is currently being used? I'm wanting to dynamically detect what export format is being used and show or hide report elements based on this.
For example, if the user exports to PDF I wish to show a particular data table but if the instead export to CSV I do not.
-
Can you use a table instead? Using a table with the Print When statements will cause the table to reflow.
Using your example if I hide C but leave a,b,d,e, a table will cause d to appear next to b.

I'm not sure how to solve this. So far I haven't had the need to do this. Sorry!
-
Make sure all of your fields are lined up correctly. If a field is out of line, many times items will disappear.
I've found using Tables takes out a lot of the issues we were having with excel exports. Ever since we switched from just using fields in the detail band to tabels we have had much fewer problems!
-
Check the server logs for any errors. They hould be in {INSTALL_DIR}/apache-tomcat/logs if my memory serves me correctly.

Not to hijack your post but we've seen strange behavior with the back button as well. In our case we can return to the original report from the Drilldown report, but the HTML5 chart no longer appears. (All other content does)
-
Chances are this is because you're report has two components that aren't propary aligned, or that overlap. Check to see if AJ5 is merged with AL45. If so you can probably assume the overlap is outside of the crosstab and is as a result of one of the other items in the report.
Hope this helps.

*EDIT 2*
As of Jasper 5.1, I believe Jaspersoft fixed this issue by adding a 'none' sort type. I have not tried this due to time constraints but it's worth a shot if you're on 5.1 or later.
*EDIT 1*
My orginal solution worked fine for data sets that only had one measure per category. Basically any data set that didn't have the category repeated more than once. However when the category value was repeated it viewed everything as larger than the value before it. The solution wasn't as obvious as it should have been but I simply added a check in the Comparator to detect if the two objects were equal. If they were then I return 0, otherwise return 1 as usual.
The Soltuion:
Create a comparator which always returns a value of 1 (greater than). iReport sees that the data is already in order and doesn't change anything. This allows you to define ordering at the query level! See the attached java file for more info. I've also attached a jar if you just want the fix.
To use:
Add jar to classpath.
Instantiate the custom comparator in the Comparator Expr box for the desired series or category. Enjoy query level sorting!

So right after I posted this I found the correct documentation.
Section 10.4.3 states: http://://flow.html?_flowId=searchFlow&folderUri=/reports/test
Change /reports/test with the id of the path you want to go to. In my case /public/WWW.
Hope this helps!

Is there a url to load a particular folder in the repository?

I know you said you double checked the same values on the input controls. But also ensure that the input control name matches the parameter name in your report. Secondly check the data connection. Does the server have the proper connection. Can you test this DB connection with a simple report to ensure its working. If that works, check the table with a simple report.

I was frustrated by the default sorting order on the HTML5 charts. To customize the sort order you must create a comparator. And even then you can only sort by a category or series, not by a measure! I wanted to be able to sort my data in the query to solve these problems. The GUI provided no solutions besides the limited ascending or descending selections.The Soltuion:Create a comparator which always returns a value of 1 (greater than). iReport sees that the data is already in order and doesn't change anything.

Hi,
I recently created a report and uploaded it to my jaspersoft server. Initially it worked fine. My input control appeared, I could select a date and my data appeared as expected. However when I updated to a new version of the report the input control no longer appears where I can enter data. There is just no input box! I've ensured that the parameter still exists on my report and the names match each other. Any ideas/suggestions?
I should add that other reports can use and display the input control without trouble and that creating a new input control has no effect.
The pic shows that the options tab appears but no entry is avaliable!
-
I resolved my initial issue by changing the option to plotOptions.series.marker.enabled. However it would still be nice to get a iReport Specific api. It doesn't always go 1:1 with the highcharts examples!
-
Is there a list on which options from the highcharts api have been implemented and which haven't? Some options just don't seem to apply.
For example, I'm trying to create a line chart without any markers. I've added the chart property :
plotOptions.line.marker.enabled = Boolean.FALSE
This is consistent with what can be found here: http://api.highcharts.com/highcharts#plotOptions.line.marker; yet my chart still shows with markers.
Additionally certain options work when deployed on the server but do not work in local XHTML view.
