I am now going to offer proof that Dispensationalism and Open Theism cannot logically be held together. Here is Right Idea's explanation of both positions:
Open-View -- a.k.a. an Open Theist. Can be dispensational or covenental, although most OVers are dispy. The Open View holds that God is omniscient, but because we have free will (and by God's choice), the future doesn't exist to be known, and therefore God only knows some of the future, not all of it. God knows that part of the future that He has definitely predetermined (as He did with the crucifixion and still foreknows regarding the future Tribulation). But the vast majority of the future, while extremely predictable for God, cannot be known for certain. A common false accusation against the Open View is that it limits God's omniscience, but this is absolutely untrue. God cannot know things that aren't true or don't exist. For example, God cannot know that there is a man named Bob Whippersnapper in the town of New York, Colorado. Because there is no such man and no such town. Does this limit His omniscience? Of course not; that would be silly. Likewise, God cannot know with 100% certainty (except for the aforementioned exceptions) the future, which doesn't exist to be known.
Dispensationalist -- A Christian is either Covenental or Dispensational. There is no third option. Covenental theologians believe the Body of Christ today receives all of the promises God made to Israel, and is "spiritual Israel." They believe either that We have been adopted spiritually into Israel, or we have totally and permanently replaced Israel, and God will never work with the Jews again. We dispensationalists, on the other hand, believe the Body of Christ is different from historical, spiritual, corporate Israel, that we don't receive all the promises and gifts that came as a part of Israel's covenant with God, etc. Most dispensationalists are Acts 2 Dispies, who believe there was no difference between Paul's gospel and Jesus's (and the Twelve's gospel, and that the Body of Christ began at Pentacost.
So let me summarize in backwards order:
Dispensationalism:
-There is a strong dichotomy between Israel and the Body of Christ.
-The body of Christ is not spiritual Israel.
-Thus Israel means physical Israel, not the body of Christ.
Open Theism:
-God does not know with certainty the future actions of his creatures.
-His creatures have libertarian free will to either accept or reject his offer of the gospel (as well as libertarian free will in every area of life).
OK, here is why these two cannot be logically held at the same time:
Romans 11:25,26--"For I do not desire, brethre, that you should be ignorant of this mystery, lest you should be wise in your own opinion, that hardening in part has happened to Israel until the fullness of the Gentiles has come in. And so all Israel will be saved..."
So, dispensationally, Israel here cannot refer to the body of Christ, but must refer to national, physical, ethnic Israel. Since salvation, according to Open Theism, is accomplished when a libertarian free creature believes on the gospel, and all Israel will be saved, then each member of national Israel (or at least the mass nation depending on viewpoint) must, by their own libertarian free will, choose to accept the gospel and be saved. The problem is that God cannot know the future. God cannot know who will be saved. God cannot know the future actions of his libertarian free creatures with certainty. The Holy Spirit could not have inspired Paul to write these words if Open Theism is correct, for the Holy Spirit did not know which creatures would accept the gospel! Dispensationalism and Open Theism cannot logically both be held at the same time. Either Dispensationalism must be given up, Open Theism must be given up, or both Dispensationalism and Open Theism must be given up. You cannot hold to both. It is illogical.
