Form preprocess - jira
Hi,
I have an action class responsible for form preprocessing:
public class ManageTemplates extends JiraWebActionSupport
method is connected with view:
<div class="field-group"> <label>Select user/s</label> <select id="jiraUser" name="jiraUser" multiple="multiple" class="select"> #foreach ($user in $action.getAllUsers()) <option value="$user.name">$user.displayName ($user.emailAddress)</option> #end </select> </div>
And I want to get form parameters... The easiest way is to get params via request object, but I think that's not best practise. How should I serve request? I would appreciate for source code examples:)

Hi, some webwork example below.

this.service = service;
}
protected void doValidation() {
MutableIssue issue = null;
try {
issue = service.getHelper().getIssueManager().getIssueObject(id);
} catch (DataAccessException e) {
// Error handled in service (above)
}
if (!service.canCreateExternalAttachment(getJiraServiceContext(),issue)) {
return;
}
}
public Long getId() {
return id;
}
public void setId(Long id) {
