109 PROCEDURE NAME: create_hotlink_to_details
110
111 DESCRIPTION:
112
113 The creation of the anchor from the summary frame to the detail
114 frame was very complex so I've extracted the function into its
115 own routine. I used the straight tabledata call rather than
116 the htf.anchor2 web server call because the anchor2 created an
117 HREF string that would never seem to create the proper syntax
118
119 How this call works is that the A HREF is preceeded by the indent
120 characters. This is so the indent characters are not part of the
121 anchor and therefore do not appear as underlined text. The second
122 component is the link to the url for the details frame. When using
123 frames and anchors you must provide the full url that was used to
124 create the frame including all the parameters. Since I don't store
125 this parameter in any of my pl*sql tables, I had to add this parameter
126 to all the procedures so I could pass it through.
127 The next component is the tag within the detail frame that you
128 are going to navigate to. The tag is composed of two parts.
129 The first part is the object_type_prefix
130 (ATTRIBUTE, PROCESS, NOTIFICATION, MESSAGE, MESSAGE_ATTR, etc.)
131 with a '#' in front of it to tell it that its a local
132 link in the existing frame. The second part is the internal name
133 of the object. This is followed by the frame target which is
134 DETAILS, and then the name that is displayed to the user
135 as the link name which is the display name for the object.
136 The alignment is always left and I prevented wrapping so you
137 don't get every line being double spaced if one attribute or
138 some other object is a bit longer than what fits in the summary
139 frame. This is especially effective if the user resizes the
140 summary frame down to something small.
