Error in Launching DataAssist
I kept working to get DataAssist to launch without the JavaScript error. On my home PC, I remove the "onload" in the <body> tag and saved WA_AppBuilder.htm file. Then launched DataAssist and nothing happen. I undid the file (WA_AppBuilder.htm) and launched DataAssist wizard again ... this time, no problem ... no error message popup. I don't know what happened but the problem seem to be solved. At my office, I installed the WebAssist extensions, including DataAssist, on my laptop with complete success. I use DW with the extensions on my home desktop PC and my office laptop (two PCs). Case closed.
