Description of problem:
Cannot edit configuration files using the web UI when is bigger then 32KB but we are able to upload files bigger then 32KB. 

Version-Release number of selected component (if applicable):
Satellite 5.3

How reproducible:
100% 


Steps to Reproduce:

Even changing the configuration, we still just able to edit using the WEB UI files smaller then 32Kb. 

The changes were made in the files below: 

	# /etc/rhn/rhn.conf
	# 2MB
	web.maximum_config_file_size=2097152

	#  Limit the size of POST data (in bytes)
	# 2MB
	web.post_max = 2097152

	# maximum size for a config file
	# 2MB
	web.maximum_config_file_size = 2097152

After restarting the Satellite Server (rhn-satellite restart), the problems remains. 


Actual results:
Cannot edit configuration files using the web UI when file is bigger then 32KB. 

Expected results:
Edit file using web UI when bigger then 32KB.


Additional info:

Looking into the code, we can observe some interesting points below: 


a) FileDetailsAction.java: /code/src/com/redhat/rhn/frontend/action/configuration/files/FileDetailsAction.java

<snip>
public class FileDetailsAction extends RhnAction {
 46 
 47     // REQUEST elements
<snip>
 52     public static final String MAX_SIZE          = "maxbytes";
 53     public static final String MAX_EDIT_SIZE     = "maxEditBytes";
 54     public static final String LAST_USER         = "lastUser";
 55     public static final String LAST_USER_ID      = "lastUserId";
 56     public static final String TOOLARGE          = "toolarge";

<snip>
protected void setupRequestParams(RequestContext ctx, ConfigRevision cr) {
<snip>
112	    request.setAttribute(MAX_SIZE,
113                 StringUtil.displayFileSize(
114                         Config.get().getInt(ConfigDefaults.CONFIG_REVISION_MAX_SIZE,
115                                 ConfigDefaults.DEFAULT_CONFIG_REVISION_MAX_SIZE)));
116         request.setAttribute(MAX_EDIT_SIZE,
117                 StringUtil.displayFileSize(ConfigFileForm.MAX_EDITABLE_SIZE));
                                     ^^^^^^^ ---> here we can see the method requesting an attribute MAX_EDITABLE_SIZE from the class ConfigFileForm. 


b) ConfigFileForm.java: ./code/src/com/redhat/rhn/frontend/action/configuration/ConfigFileForm.java

public class ConfigFileForm extends ScrubbingDynaActionForm {
 51 
 52     /**
 53      * Comment for <code>serialVersionUID</code>
 54      */
 55     private static final long serialVersionUID = -2162768922109257186L;
 56     // configFileForm elements
	<snip>

 81     // Here to deal with form-size-limits
 82     public static final long   MAX_EDITABLE_SIZE = (32L * 1024L);
					^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ---> here we can see the attribute MAX_EDITABLE_SIZE being hardcoded set to 32KB :)

Meanwhile, the workaround is download the file locally, edit it, then upload again. That procedure works normally.
