Hi,<br><br>I'm adding support for "otherwise" to (for the time being) the guided decision table in Guvnor.<br><br>The idea being if you set a cell to represent "otherwise" the generated rule is the opposite of the accumulation of the other cells; perhaps best explained with an example:-<br>
<br><div style="margin-left: 40px;"><span style="font-family: courier new,monospace;">Person( name == )</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Mark</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">Kris</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Geoffrey</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"><otherwise></span><br style="font-family: courier new,monospace;"></div><br>This would generate:-<br><br><span style="font-family: courier new,monospace;">Person(name not in ("Mark", "Kris", "Geoffrey")</span><br style="font-family: courier new,monospace;">
<br>Equals is the simple example, this is my thoughts for the other operators we might like to support:-<br><ul><li>!= becomes "in (<list of the other cells' values)"</li><li>< becomes ">= the maximum value of the other cells' values</li>
</ul><br><div style="margin-left: 40px;">For example:-<br><br><span style="font-family: courier new,monospace;">Person ( age < )</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">10</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">20</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">30</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"><otherwise></span><br style="font-family: courier new,monospace;">
<br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Person ( age >= 30 )</span></div>
<br><ul><li><= becomes "> the maximum value of the other cells' values</li><li>> becomes "<= the minimum value of the other cells' values</li><li>>= becomes "< the minimum value of the other cells' values</li>
<li>"in" becomes "not in (<a list of all values contained in all the other cells' lists of values>)"</li></ul><div style="margin-left: 40px;">For example:-<br></div><br><div style="margin-left: 40px;">
<span style="font-family: courier new,monospace;">Person ( name in )</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Jim, Jack</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">Lisa, Jane, Paul</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"><otherwise></span><br style="font-family: courier new,monospace;">
<br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Person ( name not in ("Jim", "Jack", "Lisa", "Jane", "Paul" ) )</span><br>
<br></div><ul><li>I'm not sure there is a simple solution for "matches" and "soundslike" but welcome advice, although a possibility might be to create a compound field constraint:-<br></li></ul><div style="margin-left: 40px;">
<span style="font-family: courier new,monospace;">Person ( name soundslike )</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">Fred</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">Phil</span><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">not Person ( name soundslike "Fred" || soundslike "Phil" )</span><br style="font-family: courier new,monospace;">
</div><br><br>Would this be considered the most suitable approach?<br><br>Inputs and thoughts welcome.<br><br>Thanks,<br><br>Mike <br><br>
