gsp

问题 I'm using a GSP for sending out emails based on the MailService plug-in. The sendMail closure passes (amongst others) body(view:..., model:myModel) I know that I can access every item of the myModel Map just using ${itemName} in the GSP. However as I sometimes want to build the item name dynamically like 'item'+i , I need to have some surrounding method to access the variable. I already tried ${model.get('item'+i) , and ${params.get('item'+i) , but model is null and params is an empty Map. I

问题 I have a field in my domain object which I define as an Integer... Integer minPrice I then access it in a GSP page as follows: ${fieldValue(bean: myBean, field: 'minPrice')} and what I get in my HTML is... 100,000 which is not an Integer, it's a String. Worse still it's a formatted String in a particular locale. This is a problem because I have a SELECT control on an HTML FORM which has a (non-ordinal) range of values for minPrice which I want to store in my domain object as integers, and I

问题 I'm using grails in weblogic and need to change a class file in a exploded deploy folder. But this class is actually a gsp compiled file. So, the question is: where GSP files (.class) stay in a war ? Note: I'm using external GSPs, setting grails.gsp.view.dir in Config.groovy file. 回答1: Since Grails 1.3.5, you just have to set grails.gsp.enable.reload = true in Config.groovy or set a system property -Dgrails.gsp.enable.reload=true to the appserver (tomcat, etc.) startup. GSP reloading in WAR
