TOC in merged slave project does not find the page, but Search does

Question

I have a slave CHM file, where the TOC is non-binary. This is
merged into a master project, which also has a TOC that is
non-binary. When I view the merged project, just from RoboHelp, the
TOC includes the slave embedded properly in the master TOC.
However, clicking on a TOC in the slave products "The page cannot
be displayed". If I go to the Search tab and enter something to
search on that will bring up a topic in the slave project, then
select that topic, the topic's page is displayed properly, and if I
click back to the Contents tab, the TOC has sync-ed properly, but
still, if I click again on the same topic on the Contents tab, I
get "The page cannot be displayed" again. It seems that the TOC is
not decoding paths properly. Any ideas?

Answer 1

Merged project pages are listed in the TOC but will not
display when selected? But a Search for these ‘missing’
pages returns viewable results? You have a minor problem with your
TOC settings. Follow the procedure below to solve it:
1. Open the master project that references the external .chm
files.
2. Click the Project tab.
3. Open the Single Source Layout folder.
4. Right-click Microsoft HTML Help (Primary Layout) and
select Properties.
5. Click the Advanced button.
6. Select the TOC Styles tab.
7. Alongside the Default Window section click the drop down
and select <Default>.
8. Ensure that any previously generated .chm files are
deleted using Windows Explorer before regenerating your Primary
Layout.
Open and delete the files from the directory specified in the
Select Output Folder and File Name text box in the Properties
window attached to the Microsoft HTML Help (Primary Layout) (see
above).
9. Generate your Primary Layout.
