comment request two layers in search action of one PanelForm
Can not you clone the formPanel object replacing the protocol1 with protocol2 and launch a second request then delete cloned object? So you click once and trigger two events? I do not use this library but have done things like you wish using other libraries.

comment Blank MapServer WMS image at low zoom levels in OpenLayers
Well, try replace the projection from epsg:3857 to epsg:900913. They look quite same but they are a little different. Copy the WMS request and paste into a new browser tab. With a little lucky, if problem on Mapserver, then he will report the error on output. This should be an problem with OpenLayers computed bounds.

comment Update a newly added column of a table using ST_Intersection as a filter
Please report the count of rows into your roads table: select count(*) from roads to know if it is too many roads the problem. Could you delete road outside country named 'Sudan'? Also how did you loaded the countries into database? Did you used the shp2pgsql to create sql file ?

comment Chart inside pop up window in Javascript
So the openPopup() is asynchronous? Because Javascript interpreter will not execute the next statement until the previous return except for callbacks that are executed later on time. An alternative if no event would be execute pooling for the existance of that "div" in a window.setTimeout loop. The event callback would be much more fast.

comment Nearest Neighbor problem in Postgis 2.0 using GIST Index (<-> function)
OK so I replaced the st_centroid with the && boundbox operator. I not pretty sure this is completely right but if there is one or two geometries that has boundbox intersects so they are the closer one choices. But in case of no boudbox intersections do not this should be excluded due to this filter?
