Hi Chris,<br><br>The cluster->filter can only accept mapserver expressions, filteritem and regex at layer level does not affect this setting.<br><br>However I consider the layer level filter should probably work, could you file a ticket by adding some test data and a mapfile example?<br>

<span style="color:#1F497D">That’s a very constructive suggestion. With no mapscript involved and with the mapfile set up without a cluster class I added into the layer section:<u></u><u></u></span></p><p class="MsoNormal">
