Hello! Thank you very much for your answer. Actually, I was not enquiring about a dedicated bug fix version, but whether the next release (e.g. 6.3.1) is in sight, which, as you pointed out and as I understand, will contain all current bug fixes. Greetings, Clemens

Hello! Is there a new release of Jaspersoft Studio in sight, which contains all the recent bug fixes? Best regards Clemens

I can answer the question about the custom class not being browseable myself. The dialogue for browsing the classes is the standard Eclipse Type Selection Dialog. Thus, the problem is not Jaspersoft specific. If the classes are on the project's build path, they can be browsed. So one has to add them. Whether this can be done programmatically, I have to find out.

Additional infomation -- when adding a default expression, i.e., a concrete enum member, the report fills under Linux as well. However, when in the parameter prompt choosing a different value, the error occurs. Maybe an issue with passing values from the dialogue? Still not understood, why there is the discrepancy in behaviour.

Hello! Are you developing an Eclipse plugin as an extension to Jaspersoft Studio? In this case – for me it worked to have a file jasperreports_extension.properties on the class path (if you build with Maven, put it into the folder src/main/resources/), which contains: net.sf.jasperreports.extension.registry.factory.queryexecuters.myreporting=<YOUR_CLASS>, where YOUR_CLASS is the fully qualified class name of your implementation of net.sf.jasperreports.extensions.ExtensionsRegistryFactory The .myreporting - part seems to be arbitrary, as far as I remember, it could be anything. Best regards, Clemens

Hello! I am running and developing against JaspersoftStudio-6.3.0.final. I use the Windows (64 Bit) and the Linux (64 Bit) versions. In both cases JDK 8u102 In the course of extending Jaspersoft Studio with own datasource implementations by an Eclipse plugin, I would like to use my own classes as parameter types. In this special case, it is an enum: net.august.clemens.TimeLevelEnum. Here, I come across 2 problems. First, in the parameter property window, net.august.clemens.TimeLevelEnum is not available when opening the class browser (clicking the '...' next to the class name input). I have to input "net.august.clemens.TimeLevelEnum" by hand. Nevertheless, when running the report, I get a nice combo box with the enum members as a parameter prompt, thus the class can be used. My question – is there maybe an extension point to "register" custom classes for the parameter properties dialogue? Second, I get an error when filling the report with a parameter of type net.august.clemens.TimeLevelEnum as input for a text field. But – I get this error only, when running the Linux version, under Windows the report fills just fine with the selected member of net.august.clemens.TimeLevelEnum. Is this due to a bug in the software, or is there a likely pointer to something I am not doing properly? It would be very nice to be able to use fully integrated custom types as parameters.
