Web Screen Painter (WSP) does not allow modifying the new columns that were published.


After a site-defined schema has been published, web screen painter will consider it as a standard schema and will not allow any changes to the columns. To verify,

  1. Login to Web Screen Painter as Administrator.
  2. Go to Tools->Schema Designer and click on the custom column created (see Figure 1):

    Figure 1
    Figure 1

  3. In Figure 1, a column zTest was added to the CR object with data type as STRING and length as 150, however, web screen painter does not allow to modify the length.
  4. To modify the length of zTest, go to $NX_ROOT/site/mods and open wsp_schema.sch with a text editor (see Figure 2):

    Figure 2:
    Figure 2
  5. Change the zTest length to 250 and click on File->Save to save the changes.
  6. Go to $NX_ROOT/site/mods/majic folder and open wsp.mods file with a text editor (see Figure 3).

  7. Change the length of zTest to 250. Click on File->Save to save the changes.
  8. Click on Start ->Run ->type cmd and click OK to open the command prompt.
  9. On command prompt type the command pdm_wspupd and hit enter.
  10. pdm_wspupd compares wsp_schema.sch with wspcol table in database and indicates the changes (Figure 4).
