Hi
I have seen that DefaultHref always adds parameters to the request also when
these parameters are already present; this means that the querystring can
become too long (above all in Portal Sy). I modified the java code of
toString method. I post the modified method here. I used it in my project
and it seems to work.
public String toString()
{
StringBuffer buffer = new StringBuffer(30);
buffer.append(this.url);
if (this.parameters.size() > 0)
{
buffer.append('?');
Set parameterSet = this.parameters.entrySet();
Iterator iterator = parameterSet.iterator();
List alreadyAddedKey = Collections.synchronizedList(new
ArrayList());
while (iterator.hasNext())
{
Map.Entry entry = (Map.Entry) iterator.next();
Object key = entry.getKey();
Object value = entry.getValue();
if (value == null)
{
//According to me this is wrong; if value of parameter is
null i should put it null
//buffer.append(key).append('='); // no value
//nothing to do
}
else if (value.getClass().isArray())
{
Object[] values = (Object[]) value;
for (int i = 0; i < values.length; i++)
{
if (i > 0 && !"".equals(values[i]) &&
!alreadyAddedKey.contains(key))
{
buffer.append(TagConstants.AMPERSAND);
}
if( !"".equals(values[i]) &&
!alreadyAddedKey.contains(key)){
buffer.append(key).append('=').append(values[i]);
alreadyAddedKey.add(key);
}
}
}
else
{
if( !"".equals(value) && !alreadyAddedKey.contains(key) ){
buffer.append(key).append('=').append(value);
alreadyAddedKey.add(key);
}
}
if (iterator.hasNext()&&
!buffer.toString().endsWith(TagConstants.AMPERSAND))
{
buffer.append(TagConstants.AMPERSAND);
}
}
}
if (this.anchor != null)
{
buffer.append('#');
buffer.append(this.anchor);
}
return buffer.toString();
}
I hope this can be usefull
Regards,
Angelo.
