Back-Buttons in the WML Decks?

Question

Hi there,
another question:
why aren't there any "back" buttons in the WML Decks generated
by the AS? I'd like to be able to freely navigate through my
decks. As far as I see it at the moment, all I can do is go back
to "myHome" which is pretty cumbersome. Anything I am missing?
Regards
Jens Mueller

What you can try is to add a "back" function to your style
sheet. Most of the phones do have their own soft button to go
back to the previous page.
If you open the Service Designer search for the "myhome" line
You will see the following code:
<do type="options" label="MyHome" name="MyHome">
<go>
<xsl:variable name="myHomeHrefValue">
<xsl:value-of select="//_REQUEST_NAME"/>
<xsl:text>?</xsl:text>
<xsl:value-of select="//_SESSION"/>
</xsl:variable>
<xsl:attribute name="href">
<xsl:value-of select="p2g:encodeURL(string
($myHomeHrefValue))"/>
</xsl:attribute>
</go>
</do>
Perhaps you can try to add another label called "back". So you
will get the lines:
<do type="options" label="Back" name="Previous..">
.....and the rest of the code:
<go>
<xsl:variable name="myHomeHrefValue">
<xsl:value-of select="//_REQUEST_NAME"/>
<xsl:text>?</xsl:text>
<xsl:value-of select="//_SESSION"/>
</xsl:variable>
<xsl:attribute name="href">
<xsl:value-of select="p2g:encodeURL(string
($myHomeHrefValue))"/>
I think you will have to change the "myHomeHrefValue" in another
value for back. I havn't found out which one you could use.
Perhaps you can try something yourself.
</xsl:attribute>
</go>
</do>
Please inform me if it works!
