joinnameof

joinnameof attribute is used typically by the child elements of the library elements and causes that the name of the referred element is joined into the  element that has this attribute during the build.

This way the child-elements that are used in the library element can be given names unique in the page.

Example:

<panel name="Login" type="LoginPanel".. >

  ...

  ...

  <form name="PF" joinnameof="@LoginPanel" ..>

    ...

  <form>

</panel>

 
During build, the name of the enclosing element whose type is "LoginPanel" will be used as a prefix ("Login1_")  for the element name

<table name="Login1" .. >

  ..

  <form name="Login1_PF" .. >

    ...

  <form>
