11.  Tips and Tricks

11.1  Using debug mode

You can get debugging information about e FixIT applications by setting

debugMode

 property of the

broker component to

true

. Note that this usually creates quite a lot of information and may slow down

your application. The debug text is sent to

System.out

11.2  Using the same FileMan database file between many JSP pages

By default, the e FixIT Application Wizard creates a different JSP page for each database file. However, if

a file contains tens or even hundreds of fields, it is not convenient to have them all on the same page. In that

case, you can first create a page containing all the fields with the application wizard and then copy JSP tags

describing the fields to different pages.

Due to the nature of how HTML pages are submitted from a browser, if a user tries to edit the same

database file entry in two different JSP files the same time by switching between the pages, information will

be lost. One way to get aroung this is

not

 to use anchors

 tags) to navigate between JSP

pages, but instead

BUTTON

or

 tags. You can create a link by:

Replace anchor with a INPUT tag such as:

value= To page 2 >

Add code to the

action

event of the application:

  void this_action(ActionEvent e) {

   if (e.getAction().equals("To page 2")) {

    setForward( page_2.jsp );

    e.consume(); // the event has been handled

Another way is to navigate between JSP pages using JavaScript or to use JavaScript to

submit

 the form

when anchors are used.

11.3  Events

Usually when you want to add functionality and code to your application, you complish this by adding

events

 to the Java code. For example, if you wish to set some field values before saving a database entry,

you can add a

beforeSave

 event to the corresponding data source: In JBuilder, select you Java source file

to be edited and click  Design  tab. Select the XfijSource in question component and add an event by

double clicking

beforeSave

 entry in  Events  page. You can set a field value by:

MySource.setFieldValue( field_number , field_value );
