Hi,

I've got the following example JSON data for my jqGrid table:

[ {  "groupID": 1, "size": null }, {  "groupID": 2, "size": 1 }, {  "groupID": 1, "size": 2} ]

This corresponds to a table with 2 columns and 3 rows. Then I wanted to select only rows where the "size" attribute is greater or equal to 1. Instead of 2 rows I've got 3, including the one with "size" null. When selecting rows with "size" smaller then e.g. 3, two rows are returned correctly. I'm using jqGrid v4.5.4. As a workaround, I need to set: "size" not equals to null AND "size" >= 1 to exclude rows with null values. However, for more complex queries using the multipleSearch option I need to specify this for each column that might contain null values. Could you please help to fix this? Thanks.
