[B-frame-devel] b-frame 0.1.2

[Peter B. <pbe...@sn...>]

Hi,

<b-frame/> 0.1.2 has been released, visit http://www.b-frame.org/ and
http://sourceforge.net/projects/b-frame. This release removes the
restriction that applications have to reside under the <b-frame/> tree
and allowes to some extend the customization of masks.

1. Unbundling the Applications

Previous releases required you to have your application located under
the <b-frame/> tree in a subfolder app. As already posted by Markus
(http://sourceforge.net/mailarchive/forum.php?thread_id=1862597&forum_id=31823)
this restriction is now gone, you may locate your <b-frame/> application
wherever you want.

2. Customization of Masks

Previous <b-frame/> versions deduced the fields appearing on a mask from
the corresponding table, e.g. a tasks's select list consists of the
table's primary key attributes. This is a good default solution and may
be sufficient in some cases, but in general the fields appearing on a
mask should be customizable. This has been achieved by introducing the
<bf-app:group> and <bf-app:field> for the <b-frame/> application
descriptor. As an example consider the following task definition from
the university application.

     <bf-app:task table="institute">
       <bf-app:task table="professor">
         <bf-app:group type="list">
           <bf-app:field name="id" label="ID"/>
           <bf-app:field name="name" label="Name" link="true"/>
         </bf-app:group>
         <bf-app:task table="course">
           <bf-app:group type="list">
             <bf-app:field name="id" label="ID"/>
             <bf-app:field name="title" label="Title" link="true"/>
           </bf-app:group>
           <bf-app:task name="student_list" table="visit"/>
         </bf-app:task>
       </bf-app:task>
     </bf-app:task>

Note the following:

   * One or more <bf-app:group> tags may be nested to a <bf-app:task>
     tag for customizing a group of fields.
   * The group is identified by the type attribute of tag <bf-app:group>
     defining the mask which should be customized. For the type
     attribute the following values are allowed:
        o "list",
        o "display",
        o "insert", and
        o "update".
   * A group of a given type can occur only one time.
   * One or more <bf-app:field> tags may be nested to a <bf:-app:group>
     tag. The <bf-app:field> tag allows the following attributes:
        o The name attribute is mandatory, it has to match an attribute
          of the table corresponding to the task.
        o The label attribute is optional.
        o The link attribute is optional. It is only useful for a group
          of type "list". If set to "true", this field will have a link.
