TWRP not working correctly

[lurepheonix]

If we dont tick off the marker "Wipe cache" in the app before rebooting to recovery, our TWRPS don`t install zips.
However, with commands rewritten for Open Recovery Script it works.
This was changed in ListFilesActivity.java:
os.writeBytes("rm -f /cache/recovery/command\n");

.............................

                            } else {
                                if (selectedOpts[0]) {
                                    os.writeBytes("echo '--wipe_data' >> /cache/recovery/command\n");
                                }
                                if (selectedOpts[1]) {
                                    os.writeBytes("echo '--wipe_cache' >> /cache/recovery/command\n");
                                }

                                os.writeBytes("echo '--update_package=/" + Utils.getRcvrySdPath() + "/OTA-Updater/download/" + name + "' >> /cache/recovery/command\n");
                            }

To this:
os.writeBytes("rm -f /cache/recovery/openrecoveryscript\n");

.........

                            } else {
                                if (selectedOpts[0]) {
                                    os.writeBytes("echo 'wipe data' >> /cache/recovery/openrecoveryscript\n");
                                }

                                os.writeBytes("echo 'install /" + Utils.getRcvrySdPath() + "/OTA-Updater/download/" + name + "' >> /cache/recovery/openrecoveryscript\n");

                                if (selectedOpts[1]) {
                                    os.writeBytes("echo 'wipe cache' >> /cache/recovery/openrecoveryscript\n");
                                    os.writeBytes("echo 'wipe dalvik' >> /cache/recovery/openrecoveryscript\n");
                                }

I also added "wipe dalvik" option.
The reason must be somewhere inside the TWRP recovery, since CWM works fine.
