问题 I want to let users edit a field with double data in Grails view. I want to allow Double.NaN (to void values).

Whats the key to let it

问题 I'm using a JMS queue to read from and insert data into a postgres table created by grails. The problem is obtaining the next sequence value. I thought I had found the solution with the following statement (by putting "DEFAULT" where the ID should go), but it's no longer working. I must have changed something, because I needed to recreate the table. What's the best way to get around this problem? ps = c.prepareStatement("INSERT INTO xml_test (id, version, xml_text) VALUES (DEFAULT, 0, ?)");

问题 I am using a plugin for Grails - the Amazon S3 plugin - and the domain object provided by the plugin doesn't specify the Id Generator. I am using Postgresql and require the id genrator to be identity. I could copy the plugin in my plugins directory and mess with the domain object provided but that doesn't sound like a clean approach.Could I add the correct id generation at runtime? Or maybe there is a better way. 回答1: If you are using 1.2, you could provide a default mapping for all your GORM

问题 I'm trying to create an sql.Date by creating a Calendar object on the current date.

问题 I've found a strange issue when saving or updating several objects in Grails with MongoDB. Currently I'm using Grails 2.2.3 and MongoDB plugin 1.3.0. The problem seems to be that the instances of MiUsuario are never GC neither when I manually call the GC. In our main application we don't make batch updates, but when doing load tests (with JMeter and monitoring JVM with Java VisualVM) this problem causes memory filling and Tomcat stops responding. I've created a small new application to show
