[Users] Problem with PrintPreview ux and Proj4js

[Thomas Colley]

Thanks for replying

 

I had put the definition in but the error is the same. I have removed
all references to Proj4js from my code but just having the script
included causes the error.

 

Thanks

Did you include the definition for EPSG:27700 somewhere in your code?




Proj4js.defs["EPSG:27700"] = "+proj=tmerc +lat_0=49 +lon_0=-2
+k=0.9996012717 +x_0=400000 +y_0=-100000 +ellps=airy +datum=OSGB36
+units=m +no_defs";

	Hi

	
	I have created an OpenLayers map with print functionality using
the GeoExt.ux.PrintPreview.

	 

	This was working fine until I added the proj4js script to the
page. Now clicking on the Print button gives me the following error

	 

	TypeError: p.proj is undefined

 

if (window.Proj4js && this.proj.defData && p.proj.defData) {

	 

	When I click on the Print button 'p' is coming back in Firebug
as the value 'EPSG:4326' instead of an OpenLayers.Projection object as
it does at all other times when viewing the map.

	 

	So the main problem is that something is passing projection
through as a value instead of an object so that projection.proj is
undefined, and a further problem is that the value is for the wrong EPSG
anyway as my map is all in ESPG:27700.

	 

	Is there somewhere else within the code that I need to define
the projection? It is correctly defined in the map and comes back as

	 

	EPSG:27700 { projCode="EPSG:27700", proj={...},
titleRegEx=RegExp, more...} 

	 

	in firebug.

	 

	I have edited the code in OpenLayers 'Projection.js' to make 'p
= new OpenLayers.Projection("EPSG:27700")' and with this change the
print preview window appears as it should.

	 

	Hope somebody can help as I am stuck on this.

	 

	Many thanks

	 

	Tom
