DYNAMIC DOCX TEMPLATE

Hi,

Actually I am looking for:

• how we can add the if condition in word template. we have added like this «[#if doc.tech.showDate=="true"» but we are getting   doc.tech.showDate value as null....so throwing an error like cant compare null o string.....how to add condition in XML for that if condition
• how we can show the signature in word template...lets say for example we have 4 employees each employee will draw a sign using signature component in appian that eventually store as a document in appian. how we can put the signature document in WORD Template.

Can anyone help me on this.

Thanks in advance,

Gousii.
