I guess yes. 'adjustSizeToText()' works for text, not html. Html support for composer label was added recently to the composer label class. Please adapt the relevant lines to work with html labels too.

>Question for Marco, Why removed label, if the request doesn't define a value ? Why not used the default value ?

The idea was that the web client has the possibility to remove an advertised text label completely if it is not used. E.g. if a composition defines a text item with id 'author', the web client can simply ignore it if it does not want to have author's name printed. Note that the labels without ids are not removed as they are considered to be fix, so not subject to client text replacement (original meaning of label id was that this text item is subject to text replacement by web client. Later, the id has been generalized as an id for every item type).

Another possibility would be to remove the item only if the client gives an empty text and use the default text otherwise. What do you think?

Marco

Hi Marco and other devs,

In src/mapserver/qgsconfigparser.cpp:530 we can read :

  //replace label text
  foreach ( QgsComposerLabel *currentLabel, composerLabels )
  {
    QString title = parameterMap.value( currentLabel->id().toUpper() );

    if ( title.isEmpty() )
    {
      //remove exported labels not referenced in the request
      if ( !currentLabel->id().isEmpty() )
      {
        c->removeItem( currentLabel );
        delete currentLabel;
      }
      continue;
    }

    currentLabel->setText( title );
    currentLabel->adjustSizeToText();
  }

This code is used to draw composer label with value defined by the QGIS WMS Server Request GetPrint.

The bug defined in the issues #7894 http://hub.qgis.org/issues/7894 is probably du to the method adjustSizeToText()
Someone can confim it ?

Question for Marco, Why removed label, if the request doesn't define a value ? Why not used the default value ?
