I try to filter my store remotly with comparision. Ext.util.Filter seems to have no comparison parameter (or at least i didn't found any). Something like the following code failed. The additional parameter isn't sent to the server.
Code:
 my_store.filter([{property: "date_to", value: myDate, comparison: "ls"}]);
Is there any way to add custom parameters to your filter which can be submited to the server? Or is there an other way to solve this issue?
