Another line of reasoning here.
Based on the Society's chronology:
James was completed "before 62 C.E." (All Scripture book, p. 248)
Acts was completed in 61 C.E. and was written specifically to Theophilus.
It would be unlikely that James would have access to a personal letter written to Theophilus. In addition, Acts was writtein while Paul was in Rome. It would have taken some time to get that letter delivered to Theophilus. If James was completed "before 62 C.E.", he conceivably would have no access to the full accounts.
He would have also have not been familiar with Paul's words to Timothy in 2 Tim. 4:2 to "preach the word". Why? 2 Timothy was not completed until 65 C.E., thus those words had not been written.
He may have been familiar with Paul's words to the Colossians at Col 1:25 where Paul said it was his stewardship to preach the word fully. However, even that seems unlikely. Those were completed in 60-61 C.E. James would likely not had access to these as he had no involvement in preaching to the nations. We know that because of the words of Paul at Gal 2:9: "James and Ce′phas and John, the ones who seemed to be pillars, gave me and Bar′na·bas the right hand of sharing together, that we should go to the nations, but they to those who are circumcised." So, it would be unlikely that James had this letter in his possession when he wrote his letter.
Paul did talk personally to James three years after the Lord blinded him (Gal 1:19). Also, James was present when Paul, Barnabus and Titus went to Jerusalem to tell them about how their false brothers were promoting something that was worthless, the circumcision. During that time, Acts 15:4 tells us "they recounted the many things God had done by means of them" to the apostles, of which James was one and was present. We know that because Acts 15:13 tells us that James is the one speaking.
So, reasoning based on chronology alone, James did not have access to the same information that we do regarding preaching. His "works" would not have included that. He was well aware of Paul's stewardship, and no doubt was pleased by it. But, at Acts 15:28, 29 and at James 1:27, he said nothing about preaching as part of the things they were to do as "works" leading to salvation.
