Message definition (Development/KDevelop-PG-Qt Introduction)

You probably see the glaring error. ''try/rollback'' helps with serious problems (e.g. parser doesn't work), though often you can ignore these conflicts. But if you do so, be aware that the parser is ''greedy'': In our example ''item_list'' will always contain ''all'' ''item'' elements, and ''items'' will ''never'' have an ''item'' member. If this is an issue that leads to later conflicts, only ''try/rollback'', custom manual code to check which rule should be used, or a refactoring of your grammar structure.
