Can someone help me/us?

This evening will try jqgrid 4.4.1 to see if the problem is still there.

Thank you to everyone and in particular HGWheels for give me a simple and fast solutions. 

When the jqGridExport method is called and type jsonstring is used the "filters" section looks like this:

"filters":{"{"groupOp":"AND","rules":[{"field":"param1","op":"eq","data":"data1"},{"field":"param2","op":"cn","data":"data2"}]}"}

However the string should look like this:

"filters":"{"{"groupOp":"AND","rules":[{"field":"param1","op":"eq","data":"data1"},{"field":"param2","op":"cn","data":"data2"}]}"}"

Notice that the export function is not placing the filters inside of double quotes.  This is causing the jqGridSetParam method to try and interpret the '' escape characters.  Additionally if you were to remove the escape characters, then once the data is posted to the server the "filters" parameter is interpreted as json and is no longer valid.  We want the entire string posted to the server not the json structure.

I believe the offending lines from grid.import.js are 185 & 186:

   ret=ret.replace(/filters":"/,'filters":');
   ret=ret.replace(/}]}"/,'}]}');

I temporarily resolved the problem by doing a search/replace on the jqGridExport jsonstring with the following:

s/"filters":{/"filters":"{/gi

s/"}]}/"}]}"/gi

Someone with more experience with the jqGrid structure may need to make/advise on the source fix to resolve this issue.

When using jqGridExport and jqGridImport the operation fails when there is filter data set.  I am doing

multipleSearch: true and multipleGroup: true in my config.  I can also confirm that when there are no filters

applied the string produced by jqGridExport is successfully imported by jqGridImport as one would expect. 

When a filter is applied then jqGridExport ceases to properly be imported by jqGridImport.  I am making sure to

unload the grid using jqGrid('GridUnload') before calling jqGridImport.  Also I am not changing/formatting the string

produced by jqGridExport in any way.  As posted by panciom above I receive the same error when trying to

perform the import "invalid property id".  For what it is worth I have tested this with jsonstring and xmlstring

and both produce the same error.  It would seem that the output of jqGridExport is not properly escaping

characters when multipleSearch and multipleGroup are both turned on.

I'm trying to make a search page with the possibility to save parameters to recall the search later.

I use the following code to show the problem:

    var grid_conf=jQuery("#find").jqGrid('jqGridExport',{exptype:"jsonstring"});

    jQuery("#find").jqGrid('GridUnload');
    
    jQuery("#find").jqGrid('jqGridImport',{
        imptype: 'jsonstring',
        impstring: grid_conf
    }).trigger("reloadGrid");
}

When there are filter data (toolbar with stringResult:true or dialog search) the import fail with this error (from firefox console):

Otherwise everything work as expected.

Notice that jsonstring data are exported and imported without any intervent.
Maybe a bug???

I use jqGrid 4.4.0 and jQuery 1.7.2 and jQuery UI 1.8.21.
For every test i'm here and thanky to all for all.
