Bonjour à tous,

J'utilise iText pour générer un pdf. J'utilise les ColumnText pour éviter les orphelins. Mon problème c'est que seul mon premier titre s'affiche dans le document. Ensuite, les blocs de textes sont affichés mais pas les sous-titres respectifs...

Si une âme charitable pouvait me venir en aide... ?

D'avance merci !

EDIT :

J'ai résolu mon problème. Le fait est que je confondais le TextMode et me CompositMode. Désormais, tous mon texte s'affiche. Cependant, je n'arrive pas à garder les paragraphes ensembles... Pouvez-vous jeter un oeil à mon code et me dire ce qui foire ?

D'avance merci !!!
