Custom dynamic action not firing

Question

Using Apex 4.2.2 on 11g
I have a standard report A1
There is a column link on report A1 which refreshes chart C1 using a custom dynamic action.
The column link on report A1  has the URL set to  javascript:$.event.trigger('RefreshTrend_2', [{key_2:'#COL01#' }]);
and there is a dynamic action D1 RefreshTrend_2 which sets the value of the chart filter P17_KEY_2 to the value of the javascript variable key_2 and then refreshes chart C1
The dynamic action is custom with a type DOMObject of document and no condition
This works fine but when I add another report/chart (report A2, chart C2)  combination with a similar dynamic action (D2), D2 is a copy of D1 with the values for the variables and chart region changed.
The A2/C2 functionality works fine on its own, D2 gets fired when I click the column link, but not when there are 2 dynamic actions of custom/document on the page.
This column link on A2 only fires the dynamic action D2 if dynamic action D2 has a higher sequence than D1 (if i move it above D1 in the list it will fire, but then D1 does not fire for the column link on A1
Am I missing something?
Thanks

Here is my page source from the browser (i put in some blank lines here to separate the 3 dynamic actions)
<script type="text/javascript">
apex.da.initDaEventList = function(){
apex.da.gEventList = [
{"triggeringElement":"P17_IS_OK","triggeringElementType":"ITEM","triggeringConditionType":"NOT_NULL","bindType":"bind","bindEventType":"change",actionList:[{"eventResult":true,"executeOnPageInit":true,"stopExecutionOnError":true,"affectedElementsType":"BUTTON",javascriptFunction:apex.da.enable,"action":"NATIVE_ENABLE"},{"eventResult":false,"executeOnPageInit":true,"stopExecutionOnError":true,"affectedElementsType":"BUTTON",javascriptFunction:apex.da.disable,"action":"NATIVE_DISABLE"}]},
{"triggeringElement":"document","triggeringElementType":"DOM_OBJECT","bindType":"live","bindDelegateTo":document,"bindEventType":"RefreshTrend_2",actionList:[{"eventResult":true,"executeOnPageInit":true,"stopExecutionOnError":true,"waitForResult":true,"affectedElementsType":"ITEM","affectedElements":"P17_KEY_2",javascriptFunction:apex.da.setValue,"ajaxIdentifier":"3BB4667C9E25BFB8DCF63639507A062A88F713A193C0D30DDF1CEA8D6875A7F9","attribute01":"JAVASCRIPT_EXPRESSION","attribute05":"this.data.key_2","attribute09":"N","action":"NATIVE_SET_VALUE"},{"eventResult":true,"executeOnPageInit":true,"stopExecutionOnError":true,"affectedElementsType":"REGION","affectedRegionId":"R2959102626294614",javascriptFunction:apex.da.refresh,"action":"NATIVE_REFRESH"}]},
{"triggeringElement":"document","triggeringElementType":"DOM_OBJECT","bindType":"live","bindDelegateTo":document,"bindEventType":"RefreshTrend_1",actionList:[{"eventResult":true,"executeOnPageInit":true,"stopExecutionOnError":true,"waitForResult":true,"affectedElementsType":"ITEM","affectedElements":"P17_KEY_1",javascriptFunction:apex.da.setValue,"ajaxIdentifier":"51D6B9673F7096076392A95D9D00B417D49DEB96D878B419FC6D1E482D0AB2F0","attribute01":"JAVASCRIPT_EXPRESSION","attribute05":"this.data.key_1","attribute09":"N","action":"NATIVE_SET_VALUE"},{"eventResult":true,"executeOnPageInit":false,"stopExecutionOnError":true,"affectedElementsType":"REGION","affectedRegionId":"R2925517394066336",javascriptFunction:apex.da.refresh,"action":"NATIVE_REFRESH"}]}];
</script>
Only the first "document" dynamic action will fire, even though I fire them by name using
javascript:$.event.trigger('RefreshTrend_1', [{key_1:'#COL01#' }]); from the column link.
