create a new filter via zimlet (ZmFilterRule)?

[ersecchio]

hi,
I'm developing an zimlet for creating a FILTER

i' use this code:

this._filter = new ZmFilterRule("name filter ",true);
this._filter.setName("test");
this._condition = new ZmCondition(ZmFilterRule.C_FROM,ZmFilterRule.OP_MATCHES,"myserver@sever.net");
this._action = new ZmAction(ZmFilterRule.A_FOLDER,"myfolder");
this._filter.addCondition(this._condition);
this._filter.addAction(this._action);
this._filterRule = new ZmFilterRules(this._appCtxt);
this._filterRule.addRule(this._filter);

but this code clear the the old filter and create only the filter "name filter"...

how can I create a new filter without removing the old filter?

Tnx

In general you'd have to get the old filter then add this to the end of it and then save the complete filter, AFAIK there is no facility for appending a new filter to the current ones.
