I am creating some simple groovy classes, e.g. class Person { int age String name } that are being used in a Java method that relies on reflection to pull out the object properties, e.g. age and name. The problem is that metaClass is also showing up as a property. Updating the Java method to ignore this property is not an o...
Hi, I'm new to grails and I have a problem: I have this snippet of GSP: <g:form url="[controller:'main',action:'login']"> <label for="name">Usuario:</label><br/> <input type="text" name="name" /><br/> <label for="pass">Password:</label><br/> <input type="password" name="password"/><br/> <input type="submit" value="Logi...
I am about to build a UI in Java and I am trying to determine what I should use. I definitely don't want to use vanilla swing. The one caveat is that it has to be added inside of an existing swing application. I am looking at JavaFX and Groovy Swing Builder. For the former it looks like there is fairly poor support for embedding into sw...
Hi, I've been learning Groovy & Grails recently, and in terms of developer productivity it seems to be light years ahead of other Java solutions (Spring, Struts, EJB, JSF). If I search monster.ca, for either Groovy or Grails, 0 matches are returned, which suggest Grails isn't doing too well in terms of adoption. I realise that: Grail...

Hi, I'm in the process of upgrading a project to Groovy v1.6. When I installed IntelliJ my GROOVY_HOME env. var. was pointing to Groovy v1.5.7, but now that I've changed GROOVY_HOME to point to v1.6, it's not clear whether IntelliJ is also using the more recent version. How can I check which version of Groovy IntelliJ is using? Thanks...

Trying out the examples found on pleac.sf.net, I'm not able to get an example of ANSI colors to work on my WinXP box (Works fine on MacOS). What I've found is that on my WinXP machine, in both cygwin & DOS prompts, groovysh --color (and 'groovysh --terminal=unix') shows escape codes rather than the expected colored prompt. grep --color w...

Hi, I've been on a frustrating quest to find an IDE which provides reasonable support for Grails 1.1 development. My minimum requirements are: Supports running tests within the IDE Supports debugging within the IDE while running either the tests or the app itself Provides code-completion, including dynamic finders added to domain clas...
We have a large scale Java web application project. I am considering integrating some Groovy code in situations where I think Groovy could reduce our effort. For example, XML parsing and unit testing. Are there any "gotchas" or negative impacts for this scenario. For instance, perhaps it would make our build much more complicated. I hav...

I am experimenting with Groovy Griffon development and I am wondering what IDE to use. I am trying to use NetBeans 6.5, and I found this post http://blogs.sun.com/geertjan/entry/notes_on_converting_netbeans_grails essentially it describes forking the NetBeans trunk and hacking the Grails support; I was hoping for something more ligh...
When exception generated I want to show some additional information (source code) for particular exception. But grails have very hairy exceptions (it's all about groovy dynamic nature). It's my problem where to get and how to display source code. All I need is file/line information. So... Is there any possibility to get file and line wh...
